Unable to download img to imx8mm via uuu

 

I followed the steps to set the imx8mm to SDP mode. Then I connect type C and debug cable to my laptop.

After downloading the android_p.9.0.0 , I started to run uuu uuu-android-mx8mm-evk-emmc.lst

 

however, the windows command line froze at the following point.

The console output keeps repeating the output for a while and finally stops.

 

I used to successfully download img to emmc via uuu with one IMX8mm evk board.

However, I failed to do so with another two boards arrived later.

 

The windows CMD output

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.2.91-0-g3799f4d

Success 0 Failure 0

1:1 1/ 1 [============100%============] SDP: boot -f u-boot-imx8mm-evk-uuu.imx

 

The debug console output repeatly:
