Trouble Building Yocto Image for STM32MP157 – Missing Packages

[AriannaSmith-1]

Hi all,
I'm working with the STM32MP157-DK2 board and trying to build a custom Yocto image using the OpenSTLinux distribution. I’ve followed the official ST wiki and successfully set up the environment. However, during the build process, I’m getting errors about missing packages (e.g. qtbase, wayland), even though I included them in the local.conf and bblayers.conf.

Steps I’ve taken:

• Synced the layers using repo sync

• Checked for typos in the conf files

• Used the correct branch for my board (kirkstone)

Still no luck.

Has anyone encountered similar issues with Yocto builds on STM32MP1? Any tips for getting Qt and Wayland integrated properly? I’d also be happy to hear how others are setting up OP-TEE alongside Qt if you’ve done secure UI work.

Thanks in advance!

Hi @AriannaSmith-1,

Did you use the command 

$> bitbake-layers add-layer <your_layer>

as shown on this wiki page ?
