Hi guys,
I am working on a board's bootloader, since it was my first time to
do such a job, maybe
there are many naive mistakes. Anyway, I hope some one could guide me
in the right direction.
I use a JTAG simulator called BDI2000. From datasheet, it could
support gdb debugging. a binary file
called 'bootloader.bin' has been 'load 0x80000000 bootloader.bin BIN'
in BDI2000 telnet CLI, then I start
the cross-gdb and try to connect with simulator, here comes the errors:
(gdb) [root@rhl9 tftpboot]# mipsel-linux-gdb bootloader.elf

=====
I have referenced Embedding with GNU: the gdb Remote Serial
Protocol, 11/99, but I found no description
about rsp command 'p', and there even has no handler functions in
gdbserver: server.c: main().
Can anyone told me why my cross-gdb send a 'p' rsp command to the
BDI2000? Could I select a lower-version
gdb to avoid this problem?
