STM32F746G problem to run Topic is solved

[Kubica]

Hi,
I get the error below, if I want to start debug. I read in the forum that other people also have had such an error but no solution helps.
I can flash the device and have no problem with TrueStudio or other IDEs with their toolchain.
I use:
Chibi Studio GCC 7.0
OpenOCD:stm327x6g_eval.cfg and also tried:stm32f7discovery.cfg

with the example
C:\ChibiStudio\chibios191\testhal\STM32\STM32F7xx\USB_RAW

----------------------------------------------------------------------------

Hi,

I need to test it but cannot do it now, you could try to use an older OpenOCD version, it is possible there is a problem with the latest one.

I get the following error with ChibiStudio Preview 21 for windows. Do you mean that the OpenOCD can also be the reason here?

Should I install an older version of ChibioStudio or how can this be done to downgrade OpenOCD?

Thanks
Manfred

Hi,
I have now replaced the OpenOCD folder in "tools\openocd" with an older version and it runs now.
The version which runs is:
Open On-Chip Debugger 0.10.0+dev-00226-g1c2e3d41d (2017-12-23-10:15)

Best Regards

OK thanks, it is an OpenOCD issue then. I will plan for a version 22 as soon as possible.

The problem depends also on the hub with which I connect the board. I have two different hubs. Usb 2 and 3. Please take this into account if you fix the problem.

Hey there,
thanks for posting. We investigated more about this problem and we found out a regression in OpenOCD. I submitted the patch and I will build a new OpenOCD version as soon as the patch would be accepted.

Anyway you can easily fix your OpenOCD by replacing the script
C:\ChibiStudio\tools\openocd\scripts\target\stm32f7x.cfg with the one attached here

Is this the same problem that causes download and debug problems for the stm32f3 cdc demo?

I am using chibistudio 21 and get...

Code: Select all

Reading symbols from C:\ChibiStudio\workspace_user\Bubba_Drive_V1\build\ch.elf...done.

If so, any work on version 22?

P.S. I can download and run the demo with STM32CubeProgrammer
Replacing with openocd-0.10.0-dev-00040-gd52070c did not change anything...

Hi,

It will happen after next ChibiOS release. ChibiStudio usually follows.
