Trying to flash i.mx 8M plus with android demo binaries using uuu tool but getting a continuous error with the flashing script. (using Linux 20)

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.138-0-g051a8fe

Success 0 Failure 1
1:14 1/ 2 [HID(W):LIBUSB_ERROR_IO ] SDPS: boot -f "uuu_imx_android_flash.sh"

Hello,

I don’t know which command you have used for your test, but please try with the following:

sudo ./uuu_imx_android_flash.sh -f imx8mp -a -e

This will flash the slot a to the eMMC with default features enabled (uboot and vbmeta)

Best regards,
Aldo.

Hi,

Please make sure that you have UUU tool in the environment variable PATH. For Linux the executable will be uuu, you may download it here:

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.4.165/uuu

Even for a quick test you may place this file in the same folder as the android script.

Best regards,
Aldo.

little modification in the script and that worked

echo "uuu script generated, start to invoke uuu with the generated uuu script" if [ ${daemon_mode} -eq 1 ]; then ./uuu -d /tmp/uuu.lst else ./uuu /tmp/uuu.lst fi
