Hello,

 

I'm working on IMX 8M Mini EVK LPDDR4.

I'm trying to flash an 16 GB SD card with UUU according to this doc:

android_Q10.0.0_2.5.0_docs/Android_Quick_Start_Guide.pdf

 

After successfully flashed directly into the board eMMC before.

I would like to understand what could be the reason that it fail this process.

I installed UUU and exported it directory.

 

I tried several parameter combinations of this command with no result: 

sudo ./uuu_imx_android_flash.sh -f imx8mm -a -e -t sd

 

the output I get at this point:

This script is validated with uuu 1.3.124 version, it is recommended to align with this version.

dtbo is supported

dual slot is supported

dynamic parttition is supported

generate lines to flash u-boot-imx8mm.imx to the partition of bootloader0

generate lines to flash partition-table.img to the partition of gpt

generate lines to flash dtbo-imx8mm.img to the partition of dtbo_a

generate lines to flash boot.img to the partition of boot_a

generate lines to flash vbmeta-imx8mm.img to the partition of vbmeta_a

lpmake I 02-23 20:03:22  8014  8014 builder.cpp:937] [liblp]Partition system_a will resize from 0 bytes to 919138304 bytes

lpmake I 02-23 20:03:22  8014  8014 builder.cpp:937] [liblp]Partition vendor_a will resize from 0 bytes to 76460032 bytes

lpmake I 02-23 20:03:22  8014  8014 builder.cpp:937] [liblp]Partition product_a will resize from 0 bytes to 335372288 bytes

generate lines to flash super.img to the partition of super

uuu script generated, start to invoke uuu with the generated uuu script

./uuu_imx_android_flash.sh: line 758: uuu: command not found

 

What could cause this issue?

Thanks

Hi @ofir,

 

In this android version the controller connected to the SD card slot is set to work with Wi-Fi expansion card, in this case, if the dtbo image support Wi-Fi expansion card, then the board will not boot from SD card.

But if you still want to boot form the SD please to the dts which have this feature is the following:
