2. Known limitations

On Linux®, when a self-upgrade occurs, the STM32CubeMX V6.9.0 and the later releases do not restart automatically. The user must restart the STM32CubeMX manually to finalize the update.
For a project with both AES and mbedTLS activated, if the option “Generate peripheral initialization as a pair of '.c/.h' files per peripheral” is checked in the CodeGenerator tab, an issue occurs when compiling under IAR Embedded Workbench®. It is advised to uncheck this option.
After selecting “List Pinout Compatible MCUs”, the import process may not work properly (mainly for multicore or Arm® TrustZone®(a) enabled projects).
DMA handlers are not generated for the DCMI and PSSI peripherals.
In the case of file access issue during a compilation with some examples on partner IDEs (for instance with the “cannot open-source input file” error message), consider to move either the full package manually, or just the example. For the example, use the Example Selector from STM32CubeMX, closer to the root of the disk (long path issue).
The “CAD resources” feature may not be fully functional in the “Use System Proxy parameters” option of the [Updater Settings…]>[Connection Parameters] menu. If there is an issue, consider selecting the “Manual Configuration of Proxy Server” option instead (or “No Proxy” if the computer running STM32CubeMX has a direct connection to the Internet).
When unzipping a package on a macOS® system, use an official macOS® application such as the default graphical archive application, or the ditto tool in the command line:
$ditto -x -k setupArchive.zip
If a Linux®-like application is used (such as unzip), the expanded files lose the signature and are not recognized as signed.

2.1. When selecting microcontrollers in the STM32F4 series and STM32F7 series

IPv6 activation is not yet fully supported by the EWARM and MDK-ARM toolchains. Thus, it causes compilation errors with MDK-ARM and compilation warnings with EWARM.

2.2. When selecting microcontrollers in the STM32G0 series

Regarding the cohabitation between USB and USB Power Delivery, the VID and PID of USB Power Delivery and USB are not automatically aligned. VID/PID values must be aligned manually.
When both the USB Power Delivery and FreeRTOS™ CMSIS_V1 middleware are enabled at the same time, the FreeRTOS™ eTaskGetState parameter must be enabled in the include parameters tab.

2.3. When selecting microcontrollers in the STM32H5 series

When migrating projects with OEM-iROT boot path from STM32CubeMX V6.8.x to STM32CubeMX V6.9.2, the user might need to reconfigure ROT_Provisioning.
When the secure manager is selected, the RTC initial values must be added manually.
When the secure manager is selected, the TPC access is removed.
If the secure manager configuration is updated through the TPC used in standalone mode, the user must relaunch the provisioning.bat.
If the STM32CubeProgrammer (STM32CubeProg) installation path is updated manually in env.bat, it is later overwritten once the project is regenerated.
Using MDK-ARM without setting a boot path, when the user generates only a nonsecure project with TZEN=1 without having generated a secure project previously, a compilation error is generated. To avoid that compilation error, generate a secure project before any generation of a nonsecure project.
An issue occurs when the user:
a) Creates an STM32H573xx project with all the modes of the secure manager API enabled
b) Generates the project
c) Suspends one mode or more of the secure manager API
d) Regenerates the project
To recover from the issue, the user must remove manually before regeneration, depending on the IDE used:
- For EWARM: Middleware and secure manager API
- For MDK-ARM: Middlewares/Secure-manager-API and Application/user/non-secure/Secure-manager-API/App

2.4. When selecting microcontrollers in the STM32H5 series and STM32U5 series

In Microsoft® Azure NetX Duo, some configuration flags, which are not used in the STM32Cube firmware package examples, might be nonfunctional when combined.
In the flash memory and SRAM, the regions allocated to the applications are frozen by the boot path constraints. They cannot be modified further in the memory management tool interface. Nevertheless, external memories are still configurable and usable for user applications.

2.5. When selecting microcontrollers in the STM32H7 series

MDMA and HSEM are not supported in LL. Only HAL is supported.
When activating any mode under SPDIFRX:
- The alternate function configuration code is not generated in the HAL_SPDIFRX_MspInit function in the stm32h7xx_hal_msp.c file.
- Add the workaround code in the user section after “GPIO_InitStruct.Speed =GPIO_SPEED_FREQ_LOW;” as described in Table 2 depending on the channel and selected pin.

Table 2. Workaround for alternate function configuration code
Channel	Selected pin	Workaround code
IN0	PD7	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF; / USER CODE END alternate function configuration */
IN0	PG11	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF; / USER CODE END alternate function configuration */
IN1	PD8	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF; / USER CODE END alternate function configuration */
IN1	PG12	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF; / USER CODE END alternate function configuration */
IN2	PC4	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF; / USER CODE END alternate function configuration */
IN2	PG8	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF; / USER CODE END alternate function configuration */
IN3	PC5	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF; / USER CODE END alternate function configuration */
IN3	PG9	/* USER CODE BEGIN alternate function configuration / GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF; / USER CODE END alternate function configuration */

2.6. When selecting dual-core microcontrollers in the STM32H7 series

Only Boot 0 is supported: both cores boot at once.
Import from and to dual-core STM32H7 is not supported.
For memory-to-memory DMA or BDMA or MDMA configuration, the initialization code is generated for both cores.
OpenAMP issue when compiling under EWARM and MDK-ARM when OpenAMP is activated under STM32CubeMX:
- To avoid link errors in OpenAMP when compiling in EWARM IDE, add the next four lines of code in the linker files (.icf):
  /* Create region for OPENAMP */ define symbol __OPENAMP_region_start__ = 0x38000400; define symbol __OPENAMP_region_size__ = 0xFC00; export symbol __OPENAMP_region_start__; export symbol __OPENAMP_region_size__;
- To avoid link errors in OpenAMP when compiling in MDK-ARM IDE, add the next four lines of code in the linker files (.sct):
  ; ***** Create region for OPENAMP ***** .resource_table +0 ALIGN 4 { ; resource table *(.resource_table) } ; Shared memory area used by OpenAMP __OpenAMP_SHMEM__ 0x38000400 EMPTY 0xFC00 {}
OpenAMP under STM32CubeIDE needs linker file update:
- The following lines must be added under the .ld file:
  /* Specify the memory areas */ MEMORY { ... m_ipc_shm (RW) : ORIGIN = 0x38000400, LENGTH = 63K } /* Symbols needed for OpenAMP to enable rpmsg */ __OPENAMP_region_start__=ORIGIN(m_ipc_shm); __OPENAMP_region_end__=ORIGIN(m_ipc_shm)+LENGTH(m_ipc_shm);

2.7. When selecting microcontrollers in the STM32L5 series

Arm® TrustZone® support:
- Fixed default SAU is configured in the application partition_stm32l552xx.h and partition_stm32l562xx.h files.
- Import does not work for TrustZone® projects (TZEN=1).
To facilitate the peripheral privilege configuration, from STM32CubeMX V6.2.0, the GTZC peripheral is split into two domains: secure and nonsecure. The side effect is that, in the case of project migration from a release version before V6.2.0, if GTZC is configured in both the secure and nonsecure domains with previously configured privilege peripherals on a nonsecure peripheral, this configuration is lost during the migration. The GTZC_NS privileges must be configured again.
Regarding the cohabitation between USB and USB Power Delivery, the VID and PID of USB Power Delivery and USB are not automatically aligned. VID/PID values must be aligned manually.

2.8. When selecting microcontrollers in the STM32U5 series

Regarding the cohabitation between Azure RTOS USBX and USB Power Delivery, the VID and PID of USB Power Delivery and USBX are not automatically aligned. VID/PID values must be aligned manually.
To avoid linking issues with Keil® MDK-ARM when a USBX Core System is enabled, "Device CoreStack FS" or "Host CoreStack FS" must be enabled according to the USB_OTG_FS selected mode.
To avoid compilation issues when one DMA channel request is activated for one TIMx peripheral, replace htim_xx by htim_base. For example, replace:
__HAL_LINKDMA(htim_oc, hdma[TIM_DMA_ID_CC1], handle_GPDMA1_Channel11);
by
__HAL_LINKDMA(htim_base, hdma[TIM_DMA_ID_CC1], handle_GPDMA1_Channel11);

2.9. When selecting microcontrollers in the STM32WB series

THREAD is not supported in the power consumption calculator (PCC) for the STM32WB series.
The value of the CFG_BLE_MAX_CONN_EVENT_LENGTH parameter in the file app_conf.h is wrongly formatted: uint16_t is used instead of uint32_t. This impacts the Data Throughput of the application since the max value is 0xFFFF, while it should be 0xFFFF FFFF. The defined value must be changed manually in the generated code.

2.10. When selecting microcontrollers in the STM32WBA series

When the selected middleware is STM32WPAN for Bluetooth® Low Energy with the parameter CFG_BLE_NUM_LINK set above 8, use the Bluetooth® Low Energy link layer library LinkLayer_BLE_Basic_20_links_lib.a with the header file from the path \link_layer\ll_cmd_lib\config\ble_basic_20_links.

2.11. When selecting microcontrollers in the STM32WL series

If LoRaWAN®, SubGHZ_Phy or Sigfox middleware is used with the option Generate peripheral initialization as a pair of '.c/.h' files per peripheral disabled, it is advised to untick the visibility of the sub-GHz and IPCC peripherals in [Project Manager]>[Advanced Settings] Generated Function Calls panel to avoid an issue when compiling.
Import from and to dual-core is not working for the STM32WL series.
For dual-core products, IPCC LL + RF middleware (LoRaWAN®, Sigfox, and SubGHZ_Phy) are not supported.
If a Sigfox project is generated with MDK-ARM, the following option must be set in the project Options C/C++(AC6) panel: Misc Controls: -fshort-enums
The sub-GHz peripheral is forced on the Cortex®-M0+.
In the case of a project migration from a release version before V6.2.0, to facilitate the GTZC configuration, some previously default configuration ("enabled"/"disabled") has been moved to "default" configuration. This new state provides the default configuration of the MCU without any code generation. Users specifically needing this code generation must modify this state.
When compiling under IAR Embedded Workbench®, in case of dual-core products, the user must activate the share mode in both CM4 and CM0PLUS STLINK project options.
The "Time base: The system tick timer" value selected in the NVIC configuration panel is not used for the code generation. This value must be updated by the end user in the generated code.
KMS and STM32Cube Azure RTOS ThreadX cannot be enabled in the same core.

2.12. When selecting microprocessors in the STM32MP1 series

DMA nodes are generated in the device tree, but the DMA properties in the IP clients nodes are not generated.
Import from and to MPU projects does not work properly.
Dual-core project structure compatibility break : the action to import (migrate or continue) projects created with versions earlier than STM32CubeMX V5.3.0 is supported but requires the manual copy of USER SECTIONS for the device tree and Cortex®-M4 firmware from the former folder structure (DeviceTree/Inc/Src) to the new one (CA7/DeviceTree - CM4/Src - CM4/Inc).
Additional software is not supported.
RCC generation in Production mode is not supported on the coprocessor side. Only the Engineering mode is supported.
By default, the STM32CubeMX-generated code is compliant with the Engineering mode. Therefore, the call of the following clock functions must be removed in the Production mode since these clocks are then managed by Linux®: SystemClock_Config(), PeriphCommonClock_Config(), and HAL_RCCEx_PeriphCLKConfig():
- The system parts (SystemClock_Config() and PeriphCommonClock_Config()) can be removed in STM32CubeMX by selecting [Not Generate function call] for RCC in the Project Manager, then Advanced Settings tabs.
- HAL_RCCEx_PeriphCLKConfig() must be removed manually from file stm32mp1xx_hal_msp.c (STM32CubeMX-generated code).
- To make the user code compatible with both the engineering and production modes, the above RCC functions can be put under dynamic condition
  if(IS_ENGINEERING_BOOT_MODE()).
On macOS®, installation issues may result from the fact that the install is not signed. Use the following procedure:
- Download STM32CubeMX on a Window® OS personal computer.
- Copy the downloaded install into the macOS® personal computer.
- Launch the install.
OpenAMP warning when compiling under MDK-ARM if OpenAMP is not activated under STM32CubeMX:
- Remove the next four lines of code from the linker file (.sct) to avoid warning “No section matches pattern *(.resource_table)”:
  ; ***** Comment these four lines if OPENAMP is not used ***** .resource_table +0 ALIGN 4 { ; resource table *(.resource_table) } ; Shared memory area used by OpenAMP __OpenAMP_SHMEM__ 0x10040000 EMPTY 0x8000 {}
Device tree generation: the "pwr" user section name is changed to "pwr_regulators".
- Existing code in the "pwr" user section must be backed up and reported manually into the new "pwr_regulators" user section after code generation.
About the HRTIM peripheral: for the "Set Source Selection" & "Reset Source Selection" parameters, the "No source is selected" must be manually set for any unused source before decreasing the number of sources.
When using the STM32CubeMP13 bare-metal firmware, the secure mode of the peripheral RTC is not available for the STM32MP13xx microprocessors. It is only available when the STM32CubeMP1 MCU package is used.
When using the STM32CubeMP13 bare-metal firmware and activating Azure RTOS ThreadX, the STM32CubeIDE linker file must contain the following section to avoid compilation issues:

.stack:

{

_stack_bottom = ABSOLUTE(.) ;

/* Allocate room for stack. This must be large enough for the

IRQ, FIQ, and SYS stack if nested interrupts are

enabled.*/

. = ALIGN(8) ;

. += 32768 ;

_sp = . - 16 ;

_stack_top = ABSOLUTE(.) ;

} >RAM

_end = .;

2.13. When using the memory management tool

The options “ISR”, “BootInfo”, and “ThreadX” are not available in the linker file for the MDK-ARM toolchain.
When "ThreadHep section" is selected, the linker file is not updated accordingly.
When "isrvercor" is selected, the linker file is not updated accordingly.
When "Boot Info" is selected (available only in the STM32WB series), the linker file is not updated to reflect the change.

2.14. When using Start from Board

The functionality is fully available only for NUCLEO-C031C6.
With the NUCLEO-U5A5ZJ-Q and NUCLEO-H563ZI, the functionality is not available with TrustZone® activated.
With the FreeRTOS™ kernel, LwIP, and USB middleware, the functionality is not supported.
The functionality is not compatible with software packs implementing BSP drivers.

2.15. When using the Example Selector

When starting an example from the Example Selector and regenerating the code, some files can be duplicated. It can lead to potential compilation issues. In this case, remove the duplicated files.

2.16. When using additional software packs

If a software component refers to a specific peripheral, this peripheral must be initialized with HAL APIs (not with LL APIs).
When using dual-core devices, if a software component refers to a specific peripheral, this peripheral must be assigned only to the same core as the software component.
When a pack is disabled, the generated files are not removed from the project.
- Workaround: remove these files manually.
Possible issues with component dependencies in the Additional Software components selection window.
- Workaround: click on the refresh button from the Embedded Software Packages Manager.
When using the GNSS pack, users must not migrate their project from 3.x to 4.0.0.
Functionalities that are not supported:
- maxInstances, isDefaultVariant, generator attributes of the component element
- Dtz, Ddsp, Dsecure attributes of the condition element
- repository element
- tag and url attributes of a release element
- dominate element
- public attributes for the file element
- preIncludeLocal and preIncludeGlobal file category attributes
- Pre_Include_Local_h element
- Pre_Include_Global_h element
- Pack components where attribute values come with a "." character
Compilation issues when using both X-CUBE-AZRTOS-H7 v1.1.0 and OpenAMP middleware in the same project with minimum version MDK-ARM v5.32:
X-CUBE-AZRTOS-H7 v1.1.0 requires Arm C compiler version 6 while OpenAMP is not compatible with this version (only Arm C compiler version 5 is supported). The workaround consists in using X-CUBE-AZRTOS-H7 v1.0.0 instead. This one is compatible with Arm C compiler version 5.
In the case of an error message when downloading SEGGER I-CUBE-EMBOS:
- Download SEGGER.I-CUBE-embOS manually from the SEGGER download site at https://www.segger.com/downloads/embos.
- Open the STM32CubeMX embedded software packages manager.
- Use the option load from local and select the pack.

2.17. STM32CubeIDE toolchain

It is functional only with a Java 8 64-bit virtual machine with versions earlier than STM32CubeMX V5.6.1.

2.18. DDR test suite

STM32CubeProgrammer (STM32CubeProg) is not supported from v2.10.0 onwards.

2.19. User manual

Some chapters in the user manual STM32CubeMX for STM32 configuration and initialization C code generation (UM1718) are not fully up to date.

3. Recommendations

3.1. DDR binaries for the STM32MP1 boards

The DDR binaries needed to connect to the STM32MP1 boards are available from the GitHub website at https://github.com/ with the keyword STMicroelectronics/STM32DDRFWUTIL.

3.2. List pinout-compatible microcontrollers

The loading of microcontrollers can take a long time if all series and all packages are selected. If the loading takes too long, stop it, refine the microcontroller filters on a dedicated series or package, and restart the loading.

3.3. How to improve the wake-up from stop sequences without relying on the global SystemClock_Config()

The SystemClock_Config provided in the HAL examples is intended to be used to configure the system clock at startup. It is not recommended to use it to restore the clock settings after a Stop mode.
To keep the wake-up as quick as possible, it is highly recommended to restore only what has been changed by the hardware to enter the Low-power mode. This is typically the case for the oscillators and system clock sources. The RCC configuration registers are unchanged, and there is no need to restore them.
Typically, after a Stop mode, it is recommended to call a separate SystemClockConfig_STOP after the wake-up that enables the LSE and PLL, and selects PLL as system clock source (LSE and PLL are disabled in Stop mode). Find below an example of SystemClockConfig_STOP (provided in the HID_Standalone_LPM application):

static void SystemClockConfig_STOP(void)
{
#if defined (USB_USE_LSE_MSI_CLOCK)

/* Configures system clock after wake-up from STOP: enable LSE,

PLL and select PLL as system clock source (LSE and PLL are disabled in Stop mode) */

__HAL_RCC_LSE_CONFIG(RCC_LSE_ON);

/* Wait till HSE is ready */

while(__HAL_RCC_GET_FLAG(RCC_FLAG_LSERDY) == RESET)

{}

/* Enable the main PLL. */

__HAL_RCC_PLL_ENABLE();

/* Wait till PLL is ready */

while(__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY) == RESET)

{}

/* Select PLL as SYSCLK */

MODIFY_REG(RCC->CFGR, RCC_CFGR_SW, RCC_SYSCLKSOURCE_PLLCLK);

/* Wait till system clock switch to PLL */

while (__HAL_RCC_GET_SYSCLK_SOURCE() != RCC_CFGR_SWS_PLL)

{}

#elif defined (USB_USE_HSE_CLOCK)

/* Configures system clock after wake-up from STOP: enable HSE,

PLL and select PLL as system clock source (HSE and PLL are disabled in Stop mode) */

__HAL_RCC_HSE_CONFIG(RCC_HSE_ON);
