1. Introduction[edit | edit source]
STMicroelectronics delivers also a script runing on Linux host PC to populate ONLY the microSD card device.
This script is located here : build-<DISTRO>-<MACHINE>/tmp-glibc/deploy/images/<MACHINE>/scripts/
(Refer to OpenSTLinux_distribution article for MACHINE / DISTRO available values)
This script is also located in the Starter Package/<VERSION>/ images/<MACHINE>/scripts.
This script, as STM32CubeProgrammer tool, is using Flashlayout.tsv file in input parameter
This script creates a raw file <FlashLayoutName>.raw and a txt file <FlashLayoutName>.how_to_update.txt
Then you can use this raw file to populate your microSD card inserted on your HOST PC
2. Usage[edit | edit source]
cd build-<DISTRO>-<MACHINE>/tmp-glibc/deploy/images/<MACHINE>/scripts
./create_sdcard_from_flashlayout.sh ../flashlayout_<built-image>/<FlashLayout file>
Example :
PC $> cd build-openstlinuxweston-stm32mp2/tmp-glibc/deploy/images/stm32mp2
PC $> ./scripts/create_sdcard_from_flashlayout.sh flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp257f-ev1-optee.tsv

WARNING: before to use the command dd, please umount all the partitions
associated to SDCARD.
sudo umount `lsblk --list | grep mmcblk0 | grep part | gawk '{ print $7 }' | tr '\n' ' '`
To put this raw image on sdcard:
sudo dd if=flashlayout_st-image-weston/optee/../../FlashLayout_sdcard_stm32mp257f-ev1-optee.raw of=/dev/mmcblk0 bs=8M conv=fdatasync status=progress

(where X can be a, b, c, d, e)
To mount bootfs partition:
udisksctl mount -b /dev/disk/by-partlabel/bootfs
After the dd command you can verify if copy are correctly done and partitions take into account
sgdisk /dev/mmcblk0 -p
sgdisk /dev/mmcblk0 -v
if '-v' command indicate a problem, please execute the following command:
sgdisk /dev/mmcblk0 -e

3. Populate the microSD card inserted on your linux host PC with the created raw file[edit | edit source]
You need first to retrieve the volume name of your drive (USB Key or MMC card)
To connect a USB device to the virtual machine manually, select VM > Removable Devices > Device Name > Connect (Disconnect from host)
More explanations for this specific case here
Insert your drive then use the following command :
- In this example, the volume name is sdd (microSD card is inserted with USB key)
PC $> cat /proc/partitions major minor #blocks name 8 0 488386584 sda 8 1 999424 sda1 8 2 1 sda2 8 5 487384064 sda5 11 0 1048575 sr0 252 0 487382016 dm-0 252 1 19996672 dm-1 252 2 8335360 dm-2 252 3 459046912 dm-3 8 48 1921024 sdd
- In this example, the volume name is mmcblk0 (microSD card is inserted directly with microSD card adapter)
PC $> cat /proc/partitions major minor #blocks name 8 0 488386584 sda 8 1 999424 sda1 8 2 1 sda2 8 5 487384064 sda5 11 0 1048575 sr0 252 0 487382016 dm-0 252 1 19996672 dm-1 252 2 8335360 dm-2 252 3 459046912 dm-3 8 48 1921024 mmcblk0
 Information
|
| mmcblk0 can be replaced by: sdX if it's a device dedicated to receive the raw image (where X can be a, b, c, d, e) |
- Before using the command dd, please umount all the partitions associated to microSD card
- Example:
sudo umount `lsblk --list | grep mmcblk0 | grep part | gawk '{ print $7 }' | tr '\n' ' '`
- Populate microSD card with dd command
- Example:
cd build-openstlinuxweston-stm32mp2/tmp-glibc/deploy/images/stm32mp2 sudo dd if=FlashLayout_sdcard_stm32mp257f-ev1-optee.raw of=/dev/mmcblk0 bs=8M conv=fdatasync status=progress
The dd command takes few minutes (depending mainly of your rootfs size)
4. Update manually some partitions with dd command[edit | edit source]
Once you have populated your microSD card with the raw file, it is possible to update manually some partitions as explained in txt file.
Example :
PC $> cat FlashLayout_sdcard_stm32mp257f-ev1-optee.how_to_update.txt
This file describe How to update manually the partition of SDCARD:
1. SDCARD schema of partition
2. How to populate each partition
3. How to update the kernel/devicetree

2. How to populate each partition
---------------------------------
- Populate partition fsbla1 (/dev/mmcblk0p1)
dd if=arm-trusted-firmware/tf-a-stm32mp257f-ev1-optee-sdcard.stm32 of=/dev/mmcblk0p1 bs=1M conv=fdatasync status=progress
- Populate partition fsbla2 (/dev/mmcblk0p2)
dd if=arm-trusted-firmware/tf-a-stm32mp257f-ev1-optee-sdcard.stm32 of=/dev/mmcblk0p2 bs=1M conv=fdatasync status=progress
- Populate partition metadata1 (/dev/mmcblk0p3)
dd if=arm-trusted-firmware/metadata.bin of=/dev/mmcblk0p3 bs=1M conv=fdatasync status=progress
- Populate partition metadata2 (/dev/mmcblk0p4)
dd if=arm-trusted-firmware/metadata.bin of=/dev/mmcblk0p4 bs=1M conv=fdatasync status=progress
- Populate partition fip-a (/dev/mmcblk0p5)
dd if=fip/fip-stm32mp257f-ev1-optee-sdcard.bin of=/dev/mmcblk0p5 bs=1M conv=fdatasync status=progress
- Populate partition fip-b (/dev/mmcblk0p6)
dd if=none of=/dev/mmcblk0p6 bs=1M conv=fdatasync status=progress
- Populate partition u-boot-env (/dev/mmcblk0p7)
dd if=none of=/dev/mmcblk0p7 bs=1M conv=fdatasync status=progress

dd if=st-image-userfs-openstlinux-weston-stm32mp2.userfs.ext4 of=/dev/mmcblk0p11 bs=1M conv=fdatasync status=progress
3. How to mount manually each partition
---------------------------------
- Mount manually partition bootfs (/dev/mmcblk0p8)
udiskctl mount -b /dev/disk/by-partlabel/bootfs
- Mount manually partition vendorfs (/dev/mmcblk0p9)
udiskctl mount -b /dev/disk/by-partlabel/vendorfs
- Mount manually partition rootfs (/dev/mmcblk0p10)
udiskctl mount -b /dev/disk/by-partlabel/rootfs
- Mount manually partition userfs (/dev/mmcblk0p11)
udiskctl mount -b /dev/disk/by-partlabel/userfs
4. How to update the kernel/devicetree
--------------------------------------
The kernel and devicetree are present on "boot" partition.
To change kernel and devicetree, you can copy the file on this partitions:
- plug SDCARD on your PC
- copy kernel uImage on SDCARD
sudo cp uImage /media/$USER/bootfs/
- copy devicetree uImage on SDCARD
sudo cp stm32mp1*.dtb /media/$USER/bootfs/
- umount partitions of SDCARD
sudo umount /media/$USER/bootfs/
(dont't forget to umount the other partitions of SDCARD:
sudo umount `lsblk --list | grep mmcblk0 | grep part | gawk '{ print $7 }' | tr '\n' ' '`
)
