My board (AM335x EVM SK) does not work properly now. Seems to be an hardware issue.
If I:
1) power the board with 5V power supply
2) connect it to pc via micro usb, and sudo minicom -D /dev/ttyUSB0, it's OK
3) insert an microSD card with Android image and press the reset button
4) the first problem is: nothing is print out in minicom as usual. I get neither uboot nor kernel output.
5) adb shell, adb logcat works as usual, no problem, the android boot into GUI, nothing wrong. it works.
6) If I press anykey on keyboard in minicom, the board reboots (or reset) instantly.
Does this imply some parts on board had beed damaged? Say, usb-serial ic? Had anybody encountered the similar problem before? Any suggestion for quick fix or any workaround solution?
I will order another one but the shipment takes time. I hope I could debug some drivers this weekend and I need the kernel prints.
