| shivm28[m] | Here, GDBserver asks for the specific core register list: http://repo.or.cz/openocd.git/blob/HEAD:/src/server/gdb_server.c#l1194 | 12:45 |
|---|---|---|
| shivm28[m] | I have followed a similar approach but without providing any register map: https://github.com/shivmgg/osd-sw/blob/86cef0fd98be352f7f34443b54ada3fd23c6432c/src/libosd/gdbserver.c#L391 | 12:48 |
| shorne | shivm28[m]: yeah, I think you just need to undertsand the server working on the gdbserver to target interface | 18:01 |
|---|
| shivm28[m] | I went through the gdbserver in both qemu and openocd. IN QEMU, connection between gdb and gdbserver are implemented as: https://git.qemu.org/?p=qemu.git;a=blob;f=gdbstub.c#l1823 | 13:53 |
|---|---|---|
| shivm28[m] | 2. Regarding connections, gdbserver should first connect with GDB followed by the host controller in OSD or vice-versa. | 15:08 |
| shivm28[m] | 3. For gdbserver implementation, I am trying to cover all the API to connect it with GDB, followed by read/write registers and memory and then complete RSP implementation. | 15:16 |
| shivm28[m] | shorne: Hi, I tried using qemu from distro. But, I have qemu-system-or32 instead of qemu-system-or1k. So, couldn't follow the instructions. Finally, I went up building qemu from source following a bunch of links and resources. I was able to connect qemu gdbserver with gdb and also tried some commands. | 15:16 |
|---|---|---|
| shivm28[m] | Also, went through the implementation of gdbserver in qemu. | 15:23 |
| shorne | I hope that gives you an idea of how the gdb->gdbserver connection is done | 19:48 |
| shivm28[m] | shorne: Hi, I went through the implementation of gdbserver in openOCD. In openOCD, we can use GDB to program the board as well but that feature will be missing from the osd-gdb server, right? | 02:56 |
