OpenOCD cfg problem with LPC2148

Although I normally use CrossWorks I’d like to get OpenOCD and Insight working with a parallel port JTAG I/F for the EA LPC2148 system. When I run OpenOCD-pp I get the following errors:

C:\Program Files\openocd-2007re204\bin>openocd-pp

Info: openocd.c:93 main(): Open On-Chip Debugger (2007-09-05 09:00 CEST)

Error: arm_jtag.c:38 arm_jtag_set_instr_error_handler(): setting the new JTAG

I’m using this cfg file that is supposed to be for the LPC2148:

For more information about the configuration files, take a look at:

Hi Leon,

the syntax has changed, your line:

flash bank lpc2000 0x0 0x7D000 0 0 lpc2000_v2 0 12000 calc_checksum

must be changed to:

flash bank lpc2000 0x0 0x7D000 0 0 0 lpc2000_v2 12000 calc_checksum

Take a look here too:

http://openfacts.berlios.de/index-en.ph … figuration

AS OF R189, the order of arguments will be switched to: flash bank lpc2000 0 0 <target#>

Perhaps this will help you?

Best regards,

Michael

Hi,

as Michael already mentioned the LPC2000 flash bank command changed, but that’s only a small problem.

The real issue is the

“Error: arm_jtag.c:38 arm_jtag_set_instr_error_handler(): setting the new JTAG instruction failed, debugging is likely to be broken”

You could try the

jtag_ntrst_delay and jtag_nsrst_delay options (n in miliseconds) to give your target more time after the reset. It looks like the OpenOCD tried to select a new JTAG instruction too soon after releasing the reset.

Regards,

Dominic

Thanks. I tried both those suggestions but get this now, with really long delays (5000):

I seem to be getting closer, though.

Did you get it all to work? I'm back to tinkering with my LPC2148 boards now. Do you have a good reset script for it?
