Audiotron Firmware Update fails checksum

I've got an audiotron that will fail to boot.  I hooked up a serial port to see what was going on and got the bsquare boot loader screen.  I did an xmodem flash file update and then when trying to boot from the flash I get the checksum error message.

Calculated checksum D03ffb2b
read checksum 08a8f13c

Compressed check failure. is 065103bb should be 3d4b2bec

Here's what I've done.  I reloaded the bsquare boot image (First 64K of the flash file.)  I thought that there might be a bad firmware image of the bsquare loader.

I then tried the xmodem serial port update method and that always ends without any error messages.  When I then try to boot the firmware, I get the checksum error messages.

Does this mean that there might be some faulty flash ram chips on this box?

Thanks for any help!
