It seems, openocd currently not disables watchdog timer?

Iit is leads to panic condition after debug seesion stop on the breakpoint if user tries to execute next step manually

Temporary fix: just add CONFIG_INT_WDT=n into the project config

Expected behavior

Step by step debugging should work without CONFIG_INT_WDT=n

@denizzzka we do disable the watchdogs in every halt with this function. https://github.com/espressif/openocd-esp32/blob/master/tcl/target/esp32c3.cfg#L26

From OpenOCD's perspective, reason of the halt doesn't matter. WDTs will be disabled after step, breakpoint or manual halt command.

Perhaps you could share your application log output to see what happens during the step. You should have seen the reset reason during the next boot. Additionally, you can monitor the OpenOCD output by running it with the -d3 option.

openocd -c "telnet_port 5449" -c "gdb_port 3117" -f board/esp32c3-builtin.cfg -d3
