If so, and if all SD card work in the other boards, then we can assume a hardware failure this one board; open a support ticket.
Before you do that; check the board over with a glass, or scope (eye piece), to determine if any solder balls are left on the board from mfg; this does occur unfortunately ( I actually had one board with this problem ). Carefully check all spaces, pins, around all chips, in every connector; also look for solder bridges.
Thank you for reply.
I tried samsung,toshiba,and sillicon power Micro SD card.
But it is not changed.
I saw using ocula glass,I look for solder bridge around surface mount resister.
But I dont know this is cause of this problem or not.
can you post a close-in pic ?
