Hi,
has anyone got OpenOCD working with a Faraday FA526 processor (actually
a Raritan Kira100 which uses a FA526 processor)? It appears to be an
ARM926 variant but apparently not exactly. Does this require target
specific support or am I just missing some configuration?
I'm using an OpenOCD USB JTAG debugger from Embedded-Projects with the
following config:
#interface
interface ft2232
ft2232_vid_pid 0x0403 0x6010
ft2232_device_desc "Dual RS232"
ft2232_layout "oocdlink"
ft2232_latency 2
# 6/(1+n) Mhz TCLK
jtag_speed 1
I've used the same device successfully with a mips_m4k processor.
I've also tried speed 5 but it made no difference. My target config is:
# Target: Raritan Kira100 (Faraday FA526)
############################################
reset_config trst_and_srst
#jtag_device <IR length> <IR capture> <IR mask> <IDCODE instruction>

The halt command returns 'BUG: unknown debug reason: 0x0' but the
processor is halted. The reset command does reset.
When I try to read RAM or Flash I get no errors but the output looks the
same no matter where I read (i.e. I think it's just dumping an internal
uninitialized buffer rather than reading from the processor). A flash
probe fails.
The 'reg' command gives all the general registers as 0 which I'd think
is unlikely. ;-)
Any help at all would be greatly appreciated.
Thanks,
John McCarthy.
P.S. Here is the '-d 4' output from OpenOCD startup:
