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. http://www.s.netic.de/tmohr/linux.html Best regards, Torsten. > On Tue, Jun 25, 2002 at 10:28:02PM +0200, Torsten Mohr wrote: > > Does anybody know of patches for GDB that enable ARM debugging > > via JTAG over the parallel port? > > I don't know of any that do JTAG directly on the parallel port. > > There are several ARM JTAG interfaces that are supported by gdb: > > ARM EmbeddedICE (uses rdi target via serial/parallel) > EPI Jeeni (uses rdi target via serial or Ethernet) > ARM MultiIce (via some server program run on Windows) > Macraigor/OCDemon (via remote target) > Abatron BDIxxx (via remote target)
