Using uuu to load imx8mq eMMC

[tuban]

I am working with a custom board using an imx8mq Variscite SOM with eMMC only (no SD) and have successfully used uuu to load linux images using uuu, but am having difficulty loading android 10. I see posts for both 'uuu android.zip' and 'uuu-android-mx8mm-evk-emmc.lst', but I do not know how to create android.zip and cannot find the .lst script which I may be able to modify for my situation.

Any help would be appreciated.

My Arrow field engineer helped me discover the uuu_imx_android_flash.sh script in the android build output directory.

I've been messing with it and have made some progress, but now it appears that the eMMC load hangs. I made a couple of changes to the script to accept var-dart et al in order to align it with my build output. I also added -v -V to the uuu args.

Here is the generated uuu.lst file:

uuu_version 1.3.102
SDP: boot -f u-boot-imx8mq-var-dart-uuu.imx
SDPU: delay 1000
SDPU: write -f u-boot-imx8mq-var-dart-uuu.imx -offset 0x57c00

FB[-t 600000]: erase fbmisc
FB: set_active a

FB: done

Here is my script call and output:

Thanks for helping on this Igor. Let me explain more of the details. I am able to build the android image set successfully. I have even been able to load built images onto the variscite demo board, which has SD. My problem is loading our custom board which only has eMMC. I am running under Ubuntu, not windows. I have successfully used the uuu tool under Ubuntu to load the linux build onto eMMC (via USB). I see references to being able to either use 'uuu android.zip' to load eMMC via USB and 'uuu uuu-android-mx8mm-evk-emmc.lst'. I believe that if I can find a .lst file example, I can tailor it to our system. Or, if I knew what files to zip together, that may work too. I just don't see instructions for either of these in the documentation or other forum questions. Do I really have to run Windows to do this?
