Hi Community,

     We got a IMX53-START-R board this morning, but the board can not work at all now (make us very sad because we do need this board to do verification).  When the board was power on, only FLT(red) and 5V(green) is lighted, but both of them are blinking and none of them are stay on stable status. The blink frequency is about 2 times per seconds. The DB9 serial port doesn't output any message when board power on. So can anybody tell me what's happening? the SD card (with ubuntu image) is broken or the power manager unit is bad now? Any suggest is appreciated!
