i.MX8QM Android Automotive 14 Flash the Build to an SD Card

Hello,

I built Android Automotive OS 14.0.0_1.1.0 for my i.MX8QM MEK board.

I want to flash the resulting build into an SD card and boot from it.

I found in the past releases (AAOS 12, 13) barely mentions flashing of an SD card, but it no longer appears in the manual/guide for i.MX8's AAOS 14.

I found two posts from the same user, but the solutions aren't confirmed by the poster and do not make sense to me.

• https://community.nxp.com/t5/i-MX-Processors/iMX8QM-Android-Automotive-OS-Prepare-SD-Card-Image/m-p/...
• https://community.nxp.com/t5/i-MX-Processors/iMX8QM-Android-Automotive-Bootloader-Image-Issue/m-p/15...

Where can I find the information about how the android partitions should be arranged on an SD card?

How about reading the eMMC content and creating an SD card image literally same as the eMMC?

Hi @ycheng 

The reason for not providing SD Card boot image for Android Auto images might be like,

For consideration of security, Android auto image supports security by default.

In addition, from the perspective of practical application, normally auto applications are generally in eMMC, not SD card.

Hi Harvey,
Is there a reason that you know of? I try to port the build to an SD card flash. Maybe it could save some of my wasted effort if I can be notified about known issues with SD card boot.

Thanks,
Yanghao

Hi @ycheng 

Android auto image doesn't support for SD Card boot.
