68300

In my day job I use DIAB DCC and SDS with either a Macraigor wiggler or a 
P&E ICD. They work. We tried CodeWarrior but (2 years ago) it wouldn't do 
things like change the VBR, promising but a non-starter.

In my hobby life I tried to put together the pieces for a low low price. 
Cheap is good. Free is better.

I didn't have much luck porting GCC and GDB for 68k to Cygwin. The problem 
stemmed from the patches needed not matching the release available. Even if 
I went back to the release that (supposedly) matched the patches...it 
didn't. The various people that maintained the patches did not have the 
associated base releases as well.

If I remember correctly, the problem was especially bad with GDB for BDM. I 
managed to get a standalone program written with the BDM libraries to 
exercise my target board with my wiggler (and managed to find that my SRAM 
would go offline if the board was turned upside down) but I was not able to 
make gdb talk bdm.

BD32 under '95 with the EFI332 PD BDM works but there is no source level 
debugging. On the other hand it does do op-code disassembly, which is more 
helpful than Macraigors OCD (Macraigor said that they do not have a 
disassembly section for CPU32 and they would not release anything that 
would allow me to make one).

Eventually I downloaded Ashware GCC, which worked straight out of the box 
and am still looking for a debugger. Perhaps the BD32 for NT will pan out 
this time.

I sent a message to Metrowerks asking if they had educational prices on 
CodeWarrior for hobbiests and they flatly refused. DIAB wanted US$5K (erk) 
for a license. Jean Labrosse suggested that I call MicroCross. Perhaps when 
I get back to the project I shall.
