hi,
I am trying to do the same thing.
I am following the directions given in this document:
https://www.nxp.com/docs/en/user-guide/Android_Auto_User's_Guide.pdf

however i see that the “build” folder is not created with the envsetup.sh file

could you give me some pointers?

thanks

[GixKi]

i solved the problem: it was a misconfiguration of the enterprise network architecture

How did you solve it?

thanks

The problem was in the download phase of the android source code. The corporate IT department had applied restrictions, so the source code had not been downloaded correctly. Once these restrictions were removed from the firewall by the IT department, I was able to do the build correctly. I hope I was of some help.

OK. Thanks!

HI @Zhiming_Liu 

1. source build/envsetup.sh

export CLANG_PATH=/opt/prebuilt-android-clang

export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-

2. lunch evk_8mp-userdebug

3. ./imx-make.sh bootloader -j24

steps i have checked is up to date. but it will throw same error.

../iMX8M/mkimage_imx8.c: In function ‘copy_file.constprop’:

Do you still have this issue?

Maybe your repo sync is not complete and miss this firmware.

Hi @Zhiming_Liu 

error: bootable/libbootloader/: platform/bootable/libbootloader checkout 3dccc2dc55b1982668c268cefc1f648e489519a4
error: Cannot checkout platform/bootable/libbootloader

error: Unable to fully sync the tree.
error: Checking out local projects failed.
Failing repos:
bootable/libbootloader
Try re-running with "-j1 --fail-fast" to exit at the first error.

repo sync fialure in bootloader part. I have tried 4 to 5 times repo sync -j1 --fail-fast but same error is throwing.

what is the solution for that?

@Adi99 

Try to delete the repo workspace and repo init again.

[Adi99]

Thanks.

@Adi99 

Please share your detailed steps. It seems that the product name you input is not correct.The correct command should be lunch evk8_mp-userdebug
