Hi, I am trying to get remote debugging with gdb to work and I'm presently stuck with 2 problems. Let ee first describe the development environment here: Target system: 68LC302 development board Host system: Linux Target and host connected via asynch serial interface. Cross development tools: binutils-2.10.2 gcc-2.95.3 newlib-1.9 gdb-5.0/5.1 (tried both) Built for m68k-coff. I use the modified gdb stub for 68k which is included in the newlib/libgloss source. The stub example in the gdb sources is basically the same. I connect gdb to the target with target async /dev/ttyS1 I have the stub basically running, I can examine variables, memory, program code on the target system, but I have the following problems: 1. Single step With all single step instructions (step, stepi etc.) gdb says: (gdb) stepi The program is running. Exit anyway? (y or n) If I say y, gdb quits, if I say n, the target executes the single step. Could this be a configuration problem? This is with both gdb-5.0 and gdb-5.1 2. Breakpoints don't work at all. gdb tries to set a breakpoint with $Z0,134f,2 which the stub does not support. In my gdb docs this command is mentioned, but optional. Can I tell gdb to set the trap instruction via a meory write? I think there must be a way not to use the Z command, because the gdbstubs project on sourceforge doesn't support it either. Of course it would be possible to expand the stub to support the Z command, but I have the strong feeling that I'm missing something simple. Any help, pointers to web sites, docs etc. are welcome. Thanks in advance, Wolfgang ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe? Send a note to crossgcc-unsubscribe@sources.redhat.com
