Open source ARM Debugger
I am getting this output when I am issuing this command:

$ sudo openocd -f board/MyBuspirate.cfg -f board/linksys-wrt54gl.cfg

where, board/MyBuspirate.cfg:
buspirate_port /dev/ttyUSB0
buspirate_vreg 0
buspirate_mode normal
buspirate_pullup 1
buspirate_speed normal
reset_config srst_only

and the board/linksys-wrt54gl.cfg:
# Linksys WRT54GL v1.1
source [find target/bcm5352e.cfg]
set partition_list {
CFE { Bootloader 0x1c000000 0x00040000 }

# External 4MB NOR Flash (Intel TE28F320C3BD90 or similar)
flash bank $_FLASHNAME cfi 0x1c000000 0x00400000 2 2 $_TARGETNAME

and the source, target/bcm5352e.cfg , it refers to:

set _CHIPNAME bcm5352e
set _CPUID 0x0535217f

jtag newtap $_CHIPNAME cpu -irlen 8 -ircapture 0x1 -irmask 0x1f -expected-id $_CPUID

target create $_TARGETNAME mips_m4k -endian little -chain-position $_TARGETNAME

gdb_memory_map disable
$_TARGETNAME configure -event gdb-attach {

I want to be able to Debug the JTAG tap: bcm5352e.cpu that i have defined using gdb. I am able to connect to the gdb server that openocd listens on, but looking at the registers, and instruction pointers etc. is saying garbage.
I am not sure, if the Bus Pirate is working as expected and it is in JTAG mode?? I assume yes, because in the output it says: Info : only one transport option; autoselect 'jtag'.
Do you have any ideas about why i am getting the errors, the unexpected ID codes? And greatly appreciated for generally other points, tips and tricks?
