gdb-h8-stub... please help.

[Alexei Minayev <aminayev@yahoo.com>]

Dear GDB gurus,

I'm new to this list, and I'd appreciate your expertise.
I'm developing a gdb-stub for a Hitachi platform. I'm done with the hardware
part, but my stub and the gdb have problem understanding each other.
I compile my test program and fire up the gdb...


(gdb) set remotedebug 1
(gdb) load
...
Start address 0x200144 , load size 352
Sending packet: $P9=00200144#51...Ack
Packet received: OK

(gdb) b main

<Looks OK so far, but then>

(gdb) step

<very confusing, and then some>

(gdb) cont
Continuing.

I would appreciate any light that you can shine on this. Do I need to patch
GDB? Do I need to process binary downloading (I don't do it now)? Add extra
cases to my command switch?

Thanks a lot!

Regards -- Alexei
