imx8-mini-evk-sdk-build-doesnt-boot-kernel

[Flora1]

Hello,
I am working on imx8 mini. evk board. I have tried to generate image by android build with the help of following document:
https://www.nxp.com/docs/en/user-guide/ANDROID_USERS_GUIDE.pdf

After following the above given steps for generating image, I have tried to flash. But after flashing kernel is getting stuck. Followed the steps for customise kernel as mention in document and tried to flash .

For cross check I have tried default image and it was flashed and boot successfully.
Attaching error logs in which my kernel is getting stuck:

Please share your build steps and log. Your build may be incomplete.

[Flora1]

source ~/imx-android-13.0.0_2.2.0/imx_android_setup.sh 

export MY_ANDROID=`pwd`

cd ${MY_ANDROID}

 source build/envsetup.sh

lunch evk_8mm-userdebug

  ./imx-make.sh -j4 2>&1 | tee build-log.txt

cross compiler : gcc-arm-9.2-2019.12-x86_64-aarch64-none-elf/bin/aarch64-none-elf-

this are the steps followed from the documents .

Attaching error logs

[Zhiming_Liu]

log.txt is boot log, not aosp build log.

[Zhiming_Liu]

Checked the bulid log, no issue.

How did you flash your build image?

[Flora1]

1. Download the UUU binary file from GitHub as described before. Install UUU into a directory contained by the system environment variable of "PATH".
2. Make the board enter serial download mode.
For Rev. C2 boards, change the first four bits of board's sw1101 to 1000 (from 1-4 bit) to enter serial
download mode.
3. Power on the board. Use the USB cable on the board OTG port to connect your PC with the board.
4. Decompress release_package/android-13.0.0_2.2.0_image_8mnevk.tar.gz. The package
contains the image files

cd ~/android_build/out/target/product/evk_8mm 

After entering to this directory run this command for flash

./uuu_imx_android_flash.sh -f imx8mm -a -e

I compiled same version, it can work.

can you please share your build steps 

[Zhiming_Liu]

Same to you, you can try to clean out/ folder and rebuild it.

[Flora1]

which Ubuntu version have you used?

We are using Ubuntu  20.04.6 LTS so will it work on this host os version?
