[linuxsh-dev] problem with GDB

[Studencki P. <Paw...@er...>]

Hello,

I try to debug linux on my development board(EBX7709) with GDB. It's a
SH7709. I had problems to adapt sh-stub to my board, so I've used a part of
WinCE bootloader in function "init_bsc" and modified config.h, config.mk,
Makefile and machine/ebx.mem (for my board) The problem is, sh-stub doesn't
start alone, direct from flash memory...So I start winCe bootloader, which
starts gdb-stub, it's temporary solution probably, but it works.
I can see initial messages from GDB and when I press 'g' he replayes with a
correct string. Problems are coming, when I break kermit and start GDB
client. GDB loads only two sections and that's all. had somebody a similar
problem? Is it problem with memory configuration of sh-stub?

file: machine/ebx.mem looks like:
MEMORY
{
        ROM (rx):   ORIGIN = 0x80800000, LENGTH = 16M
        RAM (rw):   ORIGIN = 0x8c000000, l = 16M
        STACK (rw): ORIGIN = 0x8c010000, LENGTH =  4096
}   

Flash memory start 0x80800000(second part, where sh-stub has been burned),
length 16M (all flash mem)
RAM 16M



and here are GDB messages (baud and line settings are in .gdbinit):
