I am trying to port eCos to a QED RM 5231 with a custom evaluation board.
I think I have gdb_module.bin correctly running, as it gives the
string
++14$T0525:0c45c0bf00000000;1d:e81b0080ffffffff;#9e
When I try to load a program via gdb:
[root@lx39 examples]# mips64vr4300-elf-gdb -nw hello

(gdb) set remotebaud 19200
(gdb) set mips-force-32bit-saved-gpregs
No symbol "mips" in current context.
(gdb) target remote /dev/ttyS0
Remote debugging using /dev/ttyS0

(gdb) load

Ignoring packet error, continuing...
Loading section .text, size 0x9018 lma 0x801000dc
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Question:
1. What is causing the message: No symbol "mips" in current context.
I thought I included all the patches.
2. For the MIPS, what is the most stable version of egcs and gdb? Do I
still need to use the snapshots?
3. I appears that gdb is communicating with the target. Any ideas on
what is causing the packet errors? Could it be a byte ordering issue?
Thanks,
