Hi Lim,

1. You have to figure out whether your board is I.MX8MM or I.MX8MQ

Your command: .\uuu_imx_android_flash.bat -f imx8mm -a -e -u trusty

But in your screenshout, iMX8MQ is used.

2. the link is for hardware connections.

When the imx8mmevk enter ino the download mode ,it report the error 

3. the link is for i.MX8MQ , and for i.MX8MM, you can also refer to it.

Hope above information is helpful to you.

Have a nice day!
