Problems with ChibiStudio Preview 17 related to OpenOCD

[RoccoMarco]

Dear all,
I have noticed that there were some problems related to OpenOCD included in the latest version of ChibiStudio.

The main problem was that OpenOCD didn't work on Windows 32bit since I compiled it using mingw64 instead of mingw32 (definitely my bad ). Additionally at that time new STM32F7 MCUses wasn't supported.

These issues are now resolved and you can patch your ChibiStudio deleting the folder OpenOCD under C:/ChibiStudio/tools and adding the new one attached to this thread. Most likely this new version of OpenOCD will be included in ChibiStudio Preview 18.

Let me know if someone is still experimenting any problem.
Ciao,
RM

Hi,
i use the STm32F7 Discovery board with the STM32F769. The OpenOCD session starts correctly but when i try to start the debug session with gdb it fails.
The OpenOCD output is as follows:

The STM32F7 discovery with STM32F746 works correctly. What i am doing wrong?

Thanks a lot.

This because current version of open ocd doesn't support new STM32F7. I will keep you up to date.

Hey there,
I have just compiled again OpenOCD. The support for STM32F756 has been introduced. I have tested it on win7-64bit and win7-32bit succesfully.
I have successfully flashed the new STM32F7 discovery demo which is available on trunk.

This is the direct link for the download. I have uploaded it on playembedded:

Hi all,
I have compiled a new version of OpenOCD which supports STM32L432. I have tested it on win7-64bit and win7-32bit succesfully.
I have successfully flashed the new STM32 NUCLEO-L432 demo which will be available on trunk in the next hours.

This is the direct link for the download. I have uploaded it on playembedded:

You can download it now

Hello.

I have compiled a new version of OpenOCD which supports STM32L432.

I usually use black magic probe (which run the gdb server on the stm32F1 probe chip) for my F4 and F7 project.

I am now beginning to play with nucleo L432 where it's not possible to reflash the probe with black magic probe firmware,
so i have to use stlink-v2.1.

I am trying to debug my app using openocd under linux (without eclipse), without success (I use last openocd master from git, gdb from
launchpad 5.4.1 q3 2016)

openocd launch, gdb connect to it and i am able to load program, set breakpoint, bun when i run, openocd fail and gdb remains stuck.

The link you send in the previous post expands to a set of dll and exe for windows, did you apply any patch(s) to the openocd trunk ?, and if yes, can you send a pointer to the patch(s), so that i can apply them and build a linux version ?

Thanks
Alexandre

Hi,
right now the head of OpenOCD should completely support STM32L432 ( I don't remember if at that time I had to apply some patches). I will do some tests with the fresh compiled version (which is that currently available with ChibiStudio Preview 18) this evening maybe.
