BDM LINUX-Patch for GDB with OCD-Wiggler

[Erwin Rol]

I am using the patch for GDB with a small
PCB that cleans up the LPT port signals and am
using it daily with a 860 on Linux.

Info can be found on:

http://www.vas-gmbh.de/software/mpcbdm/

And even Sergey's "simple" version worked ok , but only with 
a very short cable ( < 15 cm). The cable from the LPT port to
the PCB is about 30 cm and from the PCB to the 860 about 50 cm.
One can fine tune the time that is used to generate the pulses 
from inside GDB , this depends very much on the host CPU speed
and the cable type/length. 

I must say i haven't had an problems yet, it is as if yer debugging
a linux programm on a linux host. 


One disadvantage, it doesn't run on Windows. I could imagine someone 
writting a remote GDB server for it on 95/98 but under NT /(2000?) 
one needs a device driver to access the LTP port in "raw" mode.
