Information

[upgradable] means that the component is already installed but a newer version exists. Libcamera is already installed with the OpenSTLinux started package but does not include all ISP image quality feature. An upgrade is needed.

Important

To have all ISP image quality functionalities available, the stm32_dcmipp Linux kernel module need to be upgraded.

That why, when for the first time you request to update libcamera or any othe X-LINUX-ISP package, you have a message saying that the stm32_dcmipp Linux kernel module need to be reloaded:

Kernel module stm32_dcmipp need to be reloaded: reload on going... 

Weston is restarting... 

Kernel module stm32_dcmipp reload successfully done.

As a consequence, weston is restarted.
