I'm working on a custom MPC5200 board based heavily on the IceCube design
from Motorola/Freescale. We plan to use the u-boot bootloader.
I'm looking for a tool to allow us to burn u-boot into the flash memory on
new board (with all flash devices unprogrammed). Ideally, I'd like
something like the Jflash-linux tool used with StrongARM linux, or a
stand-along linux tool that lets us burn the memory.
Both the "MPCBDM" and "bdm4gdb" projects haven't been updated for
years. The BDM-Tools project is more active, but only seems to support
68k/Coldfire processors.
The 5200lite "IceCube" demo board came with a Metrowerks "Wiretap" BDM
interface, and a Green Hills "Slingshot" BDM module, but these seems to
require a large (and expensive) windows based "Development environment"
which is far more than we need. Are there linux based drivers for either
of these?
We may have to write our own JTAG based pin-wiggler, but this solution
tends to be extremely slow.
Thanks
Eric

I'm doing the same.

The BDI2000 from abatron, which in the US you probably want to get
from www.ultsol.com (send my commision to...). The difference between
the BDI product and others that my have similar spec sheets is that it
actually works, including the flash burning portions.
Once you have u-boot and/or the kernel up you can use them to update
flash.

As I understand it, Freescale has not publicly released the OCD interface
so that's why it's not supported in the open source community.

You could also look at magraigor.com. I had problems with their 5200 device
but they've probably got them worked out by now.

P.S. Love the way you play the guitar!

That is http://macraigor.com/ of course ;-).

P.S. The BDI2000 gets my endorsement (disclaimer: my experience is with
the 82xx family, not the 5200). You can pay more, but why settle for less?
