For logging purposes it should create files with names of the form "XXXX-YYYYYYYY.log" where X and Y are hexadecimal digits. So can you list the files on the CF card after the experiment? You can do it by typing "dir > output.txt" in the Windows command line (when the current directory is the root of the CF card) and posting the output.txt contents here.
Also I tried to write string "HELLO NOEMAN" to gupdate.gcd starting at offset 5. Can you check if it's present?
