Hi all Does anyone know how one would go about creating an interface/back-end to gdb that use JTAG/ICE to debug a target board ? I know that there are commercial offerings (e.g raven,wiggler etc from Macraigor) but I want to use my own "JTAG hardware" (similar to altera byteblaster). At the moment I am using a small program by Simon Wood to control the target processor via JTAG. This implements a simple debugger (with the JTAG "protocol" in software, unlike the commercial offerings) and connects to the target via the abovementioned "byteblaster" type cable (on parallel port). However I wish to use the superior (no offence Mr Wood) capabilities of gdb (breakpoints, stepping etc.). My feeling is that I could use the base code that I have and somehow adapt it to present an interface that GDB needs (the fundamental question: what is this interface ????). I have had a decent (I think) look around mailing list archives and the web, but it appears that there is not much on this topic. My target is an ARM920T processor.
