Reverse Polarity 5V Connection

[AndyS]

Hi All,

I just powered my BBB with the 5V power jack wired reversed.....Would this have killed the Sitara or are there some likely components I should try swapping out?  

The 3V3 rail appears fine.

No activity on the USER -LEDS.

Also is there any way of recovering data I have stored on the eMMC?

Thanks in advance.

Possibly could have killed it. Swapping processor I would think might be difficult not to mention of something else was blown, you could blow it again..

eMMC could be saved if the fix to repair it is successful and the eMMC is still working.

I suggest you request and RMA and let us see what we can do.

Thanks Gerald,  excuse my ignorance but what is a RMA and how do I request one?

Return Material Authorization. It is a process whereby broken hardware is repaired.

Thank you.  I have sent the form.

I have checked all the voltage rails and they appear correct.  I plan to check the crystal at lunchtime.

Maybe I have damaged the emmc.
