ChibiOS Free Embedded RTOS

Hi,
we want to implement some low level things in USB. For this reason we need access to the ULPI TX CMD Byte. How can I access this byte in chibios? I work with the board stm32f746G.
Is the function "lld_serve_interrupt" in port STM32 the right place to look at the ULPI TX CMDs?

Thanks for help ...

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.

Regards
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
Manfred

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

Chibi Studio GCC 7.0
OpenOCD:stm327x6g_eval.cfg and also ...
