yocto mickledore optee build for u-boot fails

[edwardmcl]

u-boot yocto build fails with this message

test -e arch/arm/dts/stm32mp157c-mydemo-mx.dtb || ( \
| echo >&2; \
| echo >&2 "Device Tree Source (arch/arm/dts/stm32mp157c-mydemo-mx.dtb) is not correctly specified."; \
| echo >&2 "Please define 'CONFIG_DEFAULT_DEVICE_TREE'"; \
| echo >&2 "or build with 'DEVICE_TREE=<device_tree>' argument"; \

arch/arm/dts/stm32mp157c-mydemo-mx.dts exists
arch/arm/dts/stm32mp157c-mydemo-mx-u-boot.dtsi exists

stm32mp157c-mydemo.dtb has been added to the Makefile

Any ideas?

Hi @edwardmcl ,

Sorry to come late in this thread. 

Are you still stuck ? If yes please provide more information about the way you configure and launch Yocto build + complete logs

Thanks

Hello,

I am facing the same issue as @edwardmcl  - are there any solutions?
I mainly followed instructions in https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package

 but it is not working.   When I build my image I get that u-boot-stm32mp fails as above . Below my log

make -f /home/luisa/dev/st/st_distro/stdistro/build-try-test1/tmp-glibc/work-shared/stm32mp151a-bitron-som/uboot-source/scripts/Makefile.build obj=arch/arm/dts dtbs
test -e arch/arm/dts/stm32mp151a-bitron-som-mx.dtb || ( \
echo >&2; \
echo >&2 "Device Tree Source (arch/arm/dts/stm32mp151a-bitron-som-mx.dtb) is not correctly specified."; \
echo >&2 "Please define 'CONFIG_DEFAULT_DEVICE_TREE'"; \
echo >&2 "or build with 'DEVICE_TREE=<device_tree>' argument"; \
echo >&2; \
/bin/false)

files

stm32mp151a-bitron-som-mx.dts 
stm32mp151a-bitron-som-mx-u-boot.dtsi

are below my building path  <builddir>/tmp-glibc/work-shared/stm32mp151a-bitron-som/uboot-source/arch/arm/dts and are as the one below my mx/bitron_som_20634519_06/CA7/DeviceTree/bitron-som/u-boot directory.

What is not clear to me is

1. are YOCTO recipes sufficient to to generate dtb files or should I do manually something additionally?

2. using OpenSTLinux distribution, should I also follow instructions at https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board ?  

Attached my mylayer/conf/machine/stm32mp151a-bitron-som.conf file (just extended to .txt for upload)

Looking forward to your answer.

Thank you.
