ESP32C3 openocd fail -- Hart is not halted! (OCD-420) #183
Description
I have been trying to get openocd functioning on the C3 for a couple of weeks now without success. Sometimes it will work for a little while and then it fails and nothing I do can revive it. So I built openocd-esp32 from source as of 10/22 to ensure I have the very latest version.
I am running nothing besides openocd from source and riscv32-esp-elf-gdb. The 'target remote :3333" command fails to execute. That is because openocd is failing to work properly.....
