@Slappy_g: Thanks. I've ordered the scope and it will be here Wednesday. I'm like a kid on (the day before) Christmas eve.

Well I followed  the instructions in post #2433, downloaded  blackfin-toolchain-2013R1_45-RC1.x86_64.tar.bz2 and unpacked it into the /opt directory on my ubuntu powered laptop, plugged in the Olimex ARM-USB-OCD adaptor and ran
sudo ./bfin-gdbproxy  --debug bfin --frequency=5000000  while in the appropriate bin directory

the result:  ./bfin-gdbproxy: 3: ./bfin-gdbproxy: Syntax error: Unterminated quoted string
I see the same error message with no arguments.

excuse me while I  |O

You are probably using 32 bit Linux with the 64bit version of the toolchain. Try the 32bit version of the toolchain blackfin-toolchain-2013R1_45-RC1.i386.tar.

That was it, Thanks.
Now its found the USB cable and has connected to the libftdi  driver
I don't have it connected to the DSO yet so it's telling me that TDO seems to be stuck at 0. That's the same message I had with the win 7 setup and the ARM-USB-OCD connected to the DSO.

I'll plug it into the DSO tomorrow and see how far I get.

As much as I understood the private key of the Ds1k has been read out of the firmware. Now it seems that the MSO behaves not the the same.  Will the JTAG method work in the same way as it does for the DS2000? or do I simply have to use other option keys? thank you for your support.

If you manage to do this and get the private key, you will have a lot of grateful people here!
