I have an update after trying some more today.  I've gotten the Altera USB-Blaster JTAG adapter to work with the blackfin tool chain.  It seems to work fine on a 32-bit Linux box.

I now have a working gdb interface after starting bfin-gdbproxy and connecting to it.  I can freely access memory and registers at this point.

If anyone else is looking for a JTAG interface for this, the knock-off Altera one (called "mini") is < $10 on eBay (US).  Working on memory dump now.

Is this the JTAG that would work? I just got my 2072A and would just love to open it and play

I have uploaded the files to...

.tar.xz ?. I have seen .tar.gz, but nothing on windows seems to recognize .xz. I tried renaming it to .tar and .tar.gz. What format is the archive please?. A search on google found linux people asking the same question :)

...

Later - 7z opens and extracts it. Should ds2k_00_sdram.bin have length of 128MB ?

@Git: xz might be more common in the Linux world --> http://en.wikipedia.org/wiki/Xz

So 7zip should do the job for windows.

Yes, that's the one.  In the JTAG connection diagram posted a little while back I used the second setup (pull-ups on TRST and SRST lines -- don't connect these to the programmer at all), but either way should work for you.

Good luck!

and that one is fairly fast?
I guess it's better then to buy this, since I dont know how to use my ft2232h card..
