Lpc2000

Thank you Dave for your hint cause it helped me so much. When I tried to read the value at this address (454) directly in some different sectors, I found that my card content dumping mechanism doesn't display correctly one fourth of a sector (128 bytes), the last portion. When I got it working right, everything had become visible.
Regards,
   Max
