Re: ARM debugging via JTAG?
Hi,
thanks for that hint, but it must be possible somehow to debug
an ARM chip with a parallel port (/dev/parport*).
Has anybody got some info about what's necessary to debug
an ARM? I took a look into gdb/rdi-share/ardi.c, hostchan.c
and devsw.c .
I still don't know exactly what's necessary to debug an ARM,
has anybody got a hint or some documentation for me what's
necessary to debug that chip?
I once wrote some very basic code to send some commands to
my ARMs JTAG state machine and could stop the core, but
couldn't yet send commands to the core.

Best regards,
Torsten.
