Other Parts Discussed in Thread: AM69A, AM69
Bought SK-AM69. The first thing I tried is to follow the Processor SDK's document, and try to boot with the default image found at
https://www.ti.com/tool/PROCESSOR-SDK-AM69?keyMatch=PROCESSOR-SDK-LINUX-AM69#downloads
I've tried the images from different versions, AM69 or AM69A; latest or previous versions. None of them works.
1. I've made sure that the switches are configured as "boot from SD card", although there are 4 switches, only 3 are documented.
2. Connected HDMI and DP displays, no display
3. Connected USB debug, used tio to monitor the outputs, only ttyUSB2 has outputs
4. The output of ttyUSB2 looks like the CPU is stuck in a restart loop, as show in the log snippet
