If you consider the fact that besides fash burning you may also  want
to  have  a  working hardware debugger, you should go for a BDI2000 -
especially for Linux, when MMU support is needed.

Both the "MPCBDM" and "bdm4gdb" projects haven't been updated for 
years.  The BDM-Tools project is more active, but only seems to support 

Tha't mostly because they are just working  fine  for  the  class  of
devices  they  have  been  designed  for.  The  MPC5200  has  no  BDM
interface,  but  a  JTAG  based  debug  interface  for  which  it  is
impossible  to  get  the necessary specifications without an NDA - an
NDA which  prevents  any  implementation  under  GPL.  Complain  with
Freescale.

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" 

And they have no idea how do deal with virtual addresses.

We may have to write our own JTAG based pin-wiggler, but this solution 
tends to be extremely slow.

It may be difficult to get the required documentation from Freescale,
and then you will probably spend more money (in terms of  your  time)
than you have to pay for a working tool (BDI2000).

Get the BDI2000. I'm very glad Wolfgang talked me into it!

Use the Slingshot and Wiretap as paperweights.
