i.MX8mm Android 10 build error

avijitnsec — Thu, 21 Jan 2021 01:26:26 GMT

Hi,

I am trying to build Android 10 for i.MX8mm board. Here are the steps I am following.

1. Download the source from link.

https://www.nxp.com/webapp/sps/download/preDownload.jsp

2.Follow the steps in README

Download and Setup Source:
-----------------------------------------
Run setup script to download Android open source and copy proprietary to source folders
Run from above the folder for setup script to work properly

$: source ./imx-android-10.0.0_2.6.0/imx_android_setup.sh

Setup build environment:
-------------------------
- Set up the environment for building. This only configures the current terminal.
$ source build/envsetup.sh

- Execute the Android lunch command.
lunch command can be issued with an argument or can be issued without the argument presenting a menu of selection.
$ lunch mek_8q-userdebug

Check Android User's Guide for more details

- Execute the "imx-make.sh" script to generate the image.
$ ./imx-make.sh -j4 2>&1 | tee build-log.txt
The output of preceding command will be written to standard output and build-log.txt.

If there is any errors when building the image, error log can be found in the build-log.txt file for checking.
