The firmware generated by Yocto cannot be downloaded.

[Dunliang]

Hi,

The bootfs firmware compiled from the Yocto environment I am using is a symbolic link. Every time the STM32CubeProgrammer software downloads this firmware, it exits directly.

I am certain that the firmware itself is fine. If I directly modify the bootfs firmware to the file pointed to by the symlink, it can be downloaded.

I don't know if the behavior of generating symlinks is controlled by ST or Yocto.

How can I avoid this problem?

 

Environment info:

  Ubuntu 24.04.2 LTS on WSL2:

•   Yocto, branch: scarthgap, commit 792d18b4cb2451b00280641403e6eaf37bd6e53f
•   meta-st-stm32mp, tag: openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11
•   meta-st-openstlinux, tag: openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11

  Windows 11:

•   STM32CubeProgrammer v2.20.0

 

Thanks

Hi @Dunliang,

 

I got information that indeed such symlink from WSL2 is not working well with CubeProg.

Manual copy is used as workaround.
