Open source ARM Debugger
By voytaschec

Hi,
I'm trying to run OpenOCD with Olimex ARM-USB-OCD and Broadcom bcm63168.
I have already installed Olimex and I thing it''s working properly (led is blinking).
In UrJTAG I have good signature and it can enter to Debug Mode.
But in OpenOCD I have still only:
Code: Select all
sudo openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg -f target/bcm63168.cfg -c
Open On-Chip Debugger 0.9.0 (2016-04-25-11:56)

For bug reports, read
	http://openocd.org/doc/doxygen/bugs.html
openocd: option requires an argument -- 'c'
adapter speed: 10 kHz
Info : auto-selecting first available session transport "jtag". To override use 'transport select <transport>'.
bcm63168.cpu
Info : clock speed 10 kHz
Error: JTAG scan chain interrogation failed: all zeroes
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: bcm63168.cpu: IR capture error; saw 0x00 not 0x01
Warn : Bypassing JTAG setup events due to errors
Or with reset_config:
Code: Select all
sudo openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg -f target/bcm63168.cfg -c "reset_config trst_and_srst"

Warn : Bypassing JTAG setup events due to errors
Of course I made bcm63168.cfg by myself based on bcm6348 and it looks like:
Code: Select all
set _CHIPNAME bcm63168
set _CPUID 0x08631617

adapter_khz 100

jtag newtap $_CHIPNAME cpu -irlen 5 -ircapture 0x1 -irmask 0x1f -expected-id $_CPUID

set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME mips_m4k -endian big -chain-position $_TARGETNAME
I'm working on Ubuntu 15.04.
When I run it with -d3 options the output is (short cut):
Code: Select all

I think that it is reading something but this something is wrong:
signature of bcm63168 is 0x00 86 31 61 7F and read is: 31 60 7f 61 31 0c 86

Have you any suggestions?
