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

[giampietroghizz]

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

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.

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]

Hi @Zhiming_Liu 

yes same error getting. again check repo sync and update you.

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
