What is the correct custom_defconfig and custom.conf for a 'custom' machine based on ccimx6ulsbc?


I included a custom machine named ‘custom’ according DIGI documentation.

I always get an error building u-boot. Some defines and structs failed during compilation.

I found out that the custom.conf and the custom_defconfig file is the key.

I tried:

  • custom_defconfig according meta-custom layer from DIGI github => failed
  • custom_defconfig according ccimx6ulsbc_defconfig from current yocto => failed
  • using ccimx6ulsbc_defconfig instead custom_defconfig in custom.conf => compiled

How does a correct custom.conf look like?
