Part Number: AM3359


Tool/software: Linux

Hi,

I am using am3359 processor in my application development.So far the board worked fine without having any issue ,but suddenly the Board not booting from eMMC and SD card.

AM335x EVM board:

while eMMC booting not received any data in the console.

while SD card booting received ''>'' symbol in the console.

I also saw the same issue in BBB board as well.

BeagleBoneBlack:

while eMMC booting not received any data in the console (without pressing any switch).

while SD card booting received ''>'' symbol in the console (pressed the S2 switch & later powered up).

What could be the problem ? any HW issue ?

Kindly help me to resolve the issue.

Thank you.
