Hi Community,

I am building android image of STM32MP157C-EV1.

I have got incompatible error when I have built as following commands.

commans:

  $ repo init -u https://github.com/STMicroelectronics/android-manifest -b refs/tags/st-android-11.0.0-2021-08-31 -m stm32mp1droid.xml

  $ repo sync

  $ source ./build/envsetup.sh

  $ lunch aosp_eval-user

  $ make -j

error:

  checkvintf E 11-10 15:16:51  206  206 check_vintf.cpp:554] files are incompatible: Runtime info and framework compatibility matrix are incompatible: No compatible kernel requirement found (kernel FCM version = 5).

  checkvintf E 11-10 15:16:51  206  206 check_vintf.cpp:554] For kernel requirements at matrix level 5, For config CONFIG_DEBUG_FS, value = y but required n

  checkvintf E 11-10 15:16:51  206  206 check_vintf.cpp:554] : Success

Obviously these files are mismatch.

  out/target/product/eval/system/etc/vintf/compatibility_matrix.5.xml

    1557:     <config>

    1558:       <key>CONFIG_DEBUG_FS</key>

    1559:       <value type="tristate">n</value>

    1560:     </config>

  out/target/product/eval/obj/PACKAGING/check_vintf_all_intermediates/kernel_configs.txt

    5548: CONFIG_DEBUG_FS=y

Which file should I change to fix this issue?

Or, is it better to fix it in another way?

As a side note, I have built successfully by chaning kernel_configs.txt.

Thanks & Regards,

Hiromichi,

    Hi Hiromichi,

    As mentioned in the wiki page https://wiki.st.com/stm32mpu-ecosystem-v2/wiki/How_to_build_STM32MPU_distribution_for_Android#Generating_the_image, it's required in case of user build to re-build the kernel. For that purpose, you have to execute the following commands in your build environment (after the lunch aosp_eval-user, but beore the make -j) :

    $ load_kernel

    $ build_kernel -i

    Regards

    Nicolas

    I have finished to build successfully.

    I had to do the setup described on the following site for the kernel building.
