Memory corrupt?



After using the Devboard LX for a full day with great results (after writng a working kernel driver for a shift register at par1 I almost started to love the board) it stopped working. The yellow LED is flashing very fast except if the board is in boot state.
 
Uploading a (previously working) image to the board takes about 40 seconds and shows the following via debug rs232:
 
---------------------------------
SET_REGISTER
0xB0000038
0x00001EF3
PACKET_INFO
0xC0004000
0x001E4000
Checksum of file is 0x00000000
JUMP
0xC0004000
---------------------------------
 
A different image had also checksum 0, so I tried a memory test:
 
etrax100boot --setreg b0000000 000095f8 --setreg b0000004 00000104 --setreg b000000c 1a200040 --setreg b0000008 00005611 --setreg b0000030 00001df0 --setreg b0000038 00001ef3 --bootfile DBG2 --memtest 0xc0000000 0xc2000000
Result:

Waiting for load info.
---------------------------------
 
Factory default didn't change anything...
 
Can I do something or is it a hardware failure?
 
Thanks for any ideas
