Hi,

I want to compile linux kernel for stm32mp157c-dk2, i followed guide in README.HOW_TO.txt and when i run command "make ARCH=arm O="$PWD/../build" multi_v7_defconfig fragment*.config" in point 5. I get following errors:

/opt/st/stm32mp1/stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9/scripts/kconfig/Makefile:109: *** No configuration exists for this target on this architecture. Stop.

/opt/st/stm32mp1/stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9/Makefile:539: recipe for target 'fragment*.config' failed

make[2]: *** [fragment*.config] Error 2

/opt/st/stm32mp1/stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9/Makefile:286: recipe for target '__build_one_by_one' failed

make[1]: *** [__build_one_by_one] Error 2

make[1]: Opuszczenie katalogu '/opt/st/stm32mp1/stm32mp1-openstlinux-4.19-thud-mp1-19-02-20/sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/build'

Makefile:146: recipe for target 'sub-make' failed

make: *** [sub-make] Error 2

I did everything before without point 4 (cuz i think it is optional) and without applying patches in point 3. because i don't know where to find this patches.

Besides this errors, some files are generated in ../build directory. Including .config and i am able to compile kernel, but when i deploy it on board, system crashes. And i think thats because of this previous errors.

Please tell me what I am doing wrong and how can i make it work

    Hi @La​ 

    README.HOW_TO.txt procedure has been carefully validated/tested and works.

    If you have properly source the SDK environnement step 2, I guess problem come from the fact you drop step 3.

    Patches are present in folder sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0

    So command to apply from sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9 is :

    for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

    Hope it help

    Hello I got the same issue but when I go to the patch directory and I do

    for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

    cannot access '../*.patch': No such file or directory

    You need to be in sources/arm-openstlinux_weston-linux-gnueabi/linux-stm32mp-4.19-r0/linux-4.19.9 directory, not in patch directory.
