Hi all,

I am trying to boot from sd card by holding S2 button. All I can see on gtkterm is CCCCCCCCC… printing. Is it trying take images from SD to get flashed in emmc?

That means that it can not see or read the uSD card, and is trying to boot from the serial port.

So, bad uSD card, or uSD card programmed wrong, or bad uSD card socket.
