openocd 0.11.0-arduino2 does not know target/rp2040.cfg

[josefwegner]

Hi,

Set up a spare Raspberry PI Pico as a Picoprobe (as described in https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf Chapter A) and tried to upload a sketch using a programmer instead of using picotool:

arduino-cli board attach -p /dev/ttyACM0 -b arduino:mbed_rp2040:pico 
arduino-cli compile
arduino-cli upload -P cmsis-dap -v

Sadly, it fails as openocd is trying to load a non-existing config:

"/home/pi/.arduino15/packages/arduino/tools/openocd/0.11.0-arduino2/bin/openocd" -d2 -s "/home/pi/.arduino15/packages/arduino/tools/openocd/0.11.0-arduino2/share/openocd/scripts/" -f interface/cmsis-dap.cfg  -f target/rp2040.cfg -c "telnet_port disabled; init; reset init; halt; adapter speed 10000; program {/tmp/arduino/sketches/CF5F9525C622B4069B93C96C38646A84/neopixel.ino.elf}; reset run; shutdown"

in procedure 'script'
at file "embedded:startup.tcl", line 26
Fehlgeschlagene Programmierung: Hochladefehler: exit status 1

boards.txt is using a wrong target:

pico.bootloader.tool=openocd
pico.bootloader.tool.default=openocd
pico.bootloader.config=-f target/rp2040.cfg
pico.bootloader.programmer=-f interface/cmsis-dap.cfg

The bundled openocd-0.11.0-arduino2 does only have the following target: ~/.arduino15/packages/arduino/tools/openocd/0.11.0-arduino2/share/openocd/scripts/target/rp2040-core0.cfg

Please either rename the file to rp2040.cfg, or update boards.txt to point to the correct file.

Using rp2040-core0.cfg also does not seem to work for me:

"/home/pi/.arduino15/packages/arduino/tools/openocd/0.11.0-arduino2/bin/openocd" -d2 -s "/home/pi/.arduino15/packages/arduino/tools/openocd/0.11.0-arduino2/share/openocd/scripts/" -f interfac

But using a stock openocd-0.12 would work fine with the given command line and target rp2040.cfg:
