How to customize the rootfs on STM32MP1?

[THuan.2]

From my preliminary survey, ST provides bootloader source code, kernel source code, and Yocto/Linux for SW developers to customize the file system (rootfs) to add/remove the open source tools and framework. Is my understanding correct?

Hi @THuan.2​ 

Guess page https://wiki.st.com/stm32mpu/wiki/Which_STM32MPU_Embedded_Software_Package_better_suits_your_needs is the right starting point for such question

Thanks @Community member​.

yes, starting from this page "https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package", I can confirm that we can use Yocto/Linux to customize our rootfs.

After doing "repo init" to fetch projects

"repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-20-02-19"

I can see

• trusted-firmware-a
• u-boot
• linux kernel 4.19.94
• other open source tools, framework, etc.
