I have followed the instructions for using openocd to debug an program, but the output I get from openocd is:

Info : Hardware thread awareness created
Info : Hardware thread awareness created
Info : RP2040 Flash Bank Command
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Info : BCM2835 GPIO JTAG/SWD bitbang driver
Info : clock speed 1001 kHz

Note that

Info : Listening on port 3333 for gdb connections

is missing.

The command line I have used is:

openocd -f interface/raspberrypi-swd.cfg -f target/rp2040.cfg

Was wondering if the fact that I am using a PicoW effects the raspberrypi-swd config?

Any clues would be appreciated.

Seems like pin #25 was faulty use wiringPi gpio toggle 6 (#25) with an LED to confirm. Modified raspberrypi-swd.cfg, rebuild openocd and all works fine now.

  • Just a reminder that if you change the config file, you need to rebuild. From the openocd directory, use make clean, then make then make install. When that is complete, reboot the pi.
