Hi zwiebum,
can you please decribe what steps (i.e commands) do you performed to flash primer with openocd? i'm also new to openocd - i was able to connect but do not kown how to flash primer.

thanks in advance.

Ok, let's assume you have a compiled program - probably Circle.hex - in your working folder. primer1 is connected, openocd is runnung. telnet to openocd with

Code:

telnet localhost 4444

Get som info about primer flash (optional, but nice too see)

Code:

flash probe 0

stm32x is locked after boot, so unock it:

Code:

stm32x unlock 0

Now you can flash your hex file:

Code:

flash write_image erase /<adsolute_path>/Circle.hex

If command sometimes fails, just retry both lines. Now you can start gdb to debug the program:

Code:

> arm-elf-gdb Circle.elf
(gdb) target remote localhost:3333
(gdb) monitor reset
(gdb) step
...

gdb sends commands with "monitor" prefix directly to openocd, so the "monitor reset" will be "reset".

Here's a console dump from the beginning of a gdb session:

Debugging with DDD and gdb: same setup as in last posting. just start ddd instead of gdb with these commands:

Code:

ddd --eval-command="target remote localhost:3333" --debugger arm-elf-gdb Circle.elf

pramode has put documentation on his site http://wiki.fosstronics.com/arm_cortex- … -c-program ( see this post for more text: http://www.stm32circle.com/forum/viewtopic.php?id=554 ) - so I suggest you go there. I'll put my stuff on his site, too :-)

I have built CircleOS 3.7 for Primer 2 under linux.

I have makefiles etc if you would like a copy.

Still no way to burn to Primer2 - have to use windows machine for the flash bit....

zwieblum · 2009-07-16 15:40:02

Well done :-)

Can you post the Makefile(s) and linker scripts?

AFAIK there is nobody working on SDW now, so there will probably be no way to use Primer2 under Linux for the next months (more likley years). I've already donated mine to a interested person. Maybe Primer3 will have JTAG again, but I do not think so.

Hey. Unfortunately, i can't provide any solution but i want to make you aware of more useful links. I guess that a bright person can add an ad-hoc support for SWD over rlink in a matter of one day of hacking:

Here's an ad-hoc patch that makes SWD work over ft2232:
https://lists.berlios.de/pipermail/open … 03742.html

Here's some information about rlink reversing history (not really useful but interesting): http://lists.berlios.de/pipermail/openo … 04082.html

Now all it takes one to ad ad-hoc support is to port SWD patch to rlink support already present in OpenOCD (the code is quite understandable). It'll not be accepted by mainline of course because it'll lack abstraction but at least it will give a way to flash primer2's without hardware mods.

Well thanks but this seems to be based on a pre 0.1.0 version of openocd which is no longer available, there is to way to get it. Or maybe over git form this not very sympathetic berlios site? (sf ripoff imo)
The problem with swd is quite frankly it's an ARM solution for ARM Architectures and nobody else uses it while JTAG rules it all. Strange world...

Oh btw, I had a quick into the the SWD Specification, and there are several ways the protocol can be used. There are several sub interfaces, ``Debug and Access Ports" in the whole SWD Protocol, among them a Common, a JTAG and native SWD variant. So until we know how SWD is done in the Primer2 I think this might be a futile attempt
Besides implementing everything in the specification from scratch and trying every Method possible.
