I have 2 issue.
1) UART0 : Character 'C' is abnoraml print.
I have new board it is really new board that no data inside emmc. first, i tried test uart boot test.
As you know. it have to display 'C' character continuous .
but, it was failed. beacause it was abnormal signal. it is different signal with BBB.
This picture is UART0_TX signla in TTL Leve. I have no idea what is it happend this delay. please advice for me.
