OK guys.....
Eventually, I got to run the JTAG dump with the Olimex ARM-USB-OCD, here are a couple of pointers....
1. When you run the Zadig utility, the drop down appears to be empty, you have to go into the menus and choose Options>List All Devices and the list will fill with the available items.
2. After the dumps, I could not find my files, they were not in the .exe directory of bfin. I went wandering through all the system directories and eventually found them in a SysWOW64 directory.
Now I ran rigup scan <filename> against them and I have the following...
RC5KEY1: XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
RC5KEY2: XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXTEAKEY: XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
PUBKEY: xxxxxxxxxxxxxxxxxx
PRIVKEY: XXXXXXXXXXXXX
SERIAL: DS2FXXXXXXXXX
I think I'm there, how do I know which one is which?
