[Skyeye-developer] testsuite blackfin

[Howard Fan]

thanks. Is the gdb remote debug supported for blackfin? Can u show us
a sample debug session?

I tried this:

~/bfin/bfin-binary-05r4-2/bfin-uclinux/bin/bfin-uclinux-gdb linux
GNU gdb 6.3.50_2004-11-25-cvs
... (skipped)
(gdb) target remote:12345
Remote debugging using :12345
Ignoring packet error, continuing...
Reply contains invalid hex digit 116
putpkt: write failed: Broken pipe.

---- another session ----
/skyeye -d -e linux
debugmode= 1, filename = (null), server TCP port is 12345
arch: blackfin
begin init emulator()
exec file "linux"'s format is elf32-little.
... (skipped)
start addr is set to 0x00001000 by exec file.
Remote debugging using host:12345

bf533_io_read_byte io error!!!addr=0xfffffffc,pc=0x1000
Illegal instruction
