PROCESSOR-SDK-AM62X: PROCESSOR-SDK-AM62X: Fail to boot from Android

Part Number: PROCESSOR-SDK-AM62X


Hello team,

We are using SDK AM62X. We want to boot from SD card, but fail. According to https://software-dl.ti.com/processor-sdk-android/esd/AM62X/08_04_00/docs/android/Overview_Flashing.html#, we do flash eMMC step by step.

Then we had stuck at "Stop at u-boot console" section, saw as below

1.3.2.1. Flashing instructions

5. Stop at u-boot console (interrupt the autoboot countdown) and do below commands to setup Android partition table

env default -f -a
run set_android_boot

We did not received any data from console, any advice?

Note all we got images is prebuilt image provided from https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-8cVNlmT7Aa/08.04.00/AM62x_08.04.00_emmc.tgz
