I have somewhat bricked the BeagleBone Black. When I boot it, when 
connected using the serial port, it does write the 'C' character 
continuously. Looking through the board I have seen the a post 
(https://groups.google.com/forum/#!topic/beagleboard/pDr_rLDYqy4) where it 
has a similar problem. I have tried reflashing the eMMC using several 
images but no luck at the moment.

Using the flasher images, this is the output using the serial port:

Looks like the flasher in the uSD isn't able even to boot. Is there any way 
to solve this problem ?

Thank you,
