Very much is different with git. Please take the time to listen to

Hi,
the first patch fixes a segfault that happens at each run of
"dump_image" command.
The bug has been introduced a couple of weeks ago in commit
3931b99d142d337ea6558fd09aad2e0812c04507
The same function "handle_dump_image_command()" does not correctly
propagate errors to the caller.
The second
Merged.
Thanks!

Hi,
This might be a silly question, but i was wondering what exactly the role of
OpenOCD is in debugging. I mean the internal functioning. I am assuming it

That does not work for me anymore since the "Cortex-M3 reset handling"
patch is in. Have you tried
"reset_config srst_only"?

You could file a bug at https://bugzilla.kernel.org/ with references
to the below discussion. That's the tracker where it should go to be

Hi Jorg,
Thanks for the reply.
I tried what you suggested, and that has helped .. However, I still have some
un-reliability related to the jtag speed setting.
If I set to 500khz, I get to the reset vector ok, but do not get to the
breakpoint at main, and the debugger goes off to the weeds.

I have found that the JTAG clock needs to be *really* low
when the system is running off an RC oscillator. Once on a
PLL, you can crank up the speed. This was observed on an
LPC1768, but also one other system I fail to recall which...
RCLK
Ok, thanks, although I still don't understand why the example LPC1768.cfg
script has the OSC startup at 4Mhz, and states you then can use 4Mhz/6
Which is roughly 500Khz ... But this doesn't work.
Do you, or anyone else, have a reset-init sequence (for the LPC1766/68) that
sets the PLL and cranks

You're not using the latest master b
Yes, you are correct, I was looking at an old script that had it set to 500khz.
I can put up with 10khz for debugging, but loading the image is too slow at
that speed. I can download the image at 500 khz ok.
Is there any way to download the imake at 500khz, then switch to 10khz for the
debugging

Look at board/mcb1700.cfg
Debugging is probably stable at higher clock rates once the PLL is running.

Hi,
Ok I have tried this. I get a fast image download, but I have slow debugging as
the clock seems to get reset back to 10khz again ..
(The JTAG clock gets limited to 6Mhz by the Turlelizer2 hardware ..)
This is the dump from gdb output ..

> mon reset halt
Resetting turns the RC oscillator back on, and you're not running
the init script to set up the PLL again...

Hi Øyvind,
Awesome! Well you have really helped me fix this, it all works great now
very reliable debugging ...
Many Thanks,

This work for me _reliable_ on a custom lpc1768 board:
adapter_khz 500
#delays on reset lines
adapter_nsrst_delay 30
adapter_nsrst_assert_width 100
jtag_ntrst_d
Hi Jorg,
Thanks but after following Øyvind's advice and setting up the PLL , I can now
run at the maximum speed of my jtag adapter (6Mhz) ..
Cheers,
Bernie

Depends on what you need to do. Scenario:
reset init
# loads app into flash
load
reset halt
# Now we're slow again
# debug slow startup w/slow clock
