Cannot see I/O Registers in Debug mode
Thank you.
If possible, make an option in the Debug menu to disable the hardware reset line and add additional options to the OpenOCD configuration file.
Changing the target file / stm32f1x.cfg file in the mcu.debug plugin does not work.
Now I configured this:
I'm using ChibiOS.
Debug Configuration -> Debuger:
1) OpenOCD Options: -c "reset_config none" -c "$_TARGETNAME configure -rtos ChibiOS"
2) Script: manual script and specifying a device and debug interface
Log OpenOCD:

Under these conditions, debugging will work without connecting a reset pin
