I don’t think these are supported, so how would I go about adding support ?
Can someone give me some quick pointers about what I need to do, obviously reading the existing code is a good place to start.
many thanks
Ben
I am currently adding support for this, so should not be to long a wait.

STM32 support has now been added to the svn trunk (rev 177).
This device has two jtag taps, so note the two two jtag devices defined below.
important parts of config are:
jtag_device 4 0x1 0xf 0xe
jtag_device 5 0x1 0x1 0x1e
target cortex_m3 little run_and_init 0
working_area 0 0x20000000 16384 nobackup
flash bank stm32x 0x08000000 0x00010000 0 0 0
see wiki for full details.

Maybe this is a bit offtopic for OpenOCD but
does anyone have info about devboards:
suppliers, price avaliability and comments,
for the STM32 chips ?
Regards,
Magnus
we have 3 STM32 development boards with prices in range $33-$80
the information will be uploaded this week on our web.
STM32 devices will be in range of $3-$4 for 1K order
ST will start shipping them in September this year
Hi,
I try to compile the latest SVN 189 and connect to my STM32 but fail. The error message shows wrong IR setting. My cfg file:

Can somebody please direct me where should I modify?
Thanks and Regards,

you should not need the srst_pulls_trst option for the cortex.
Try slowing the jtag clock down while you are testing.

Thanks! I remove the srst_pulls_trst and function works.
