Can't seem to get openocd to work on a Mac M1 Max Pro

$ ./openocd -s ../tcl -f ./interface/picoprobe.cfg -f ./target/rp2040.cfg -c "program /Users/robert/src/pico/pico-examples/build/blink/blink.elf verify reset exit"

I see the serial device /dev/tty.usbmodem101 from flashing picoprobe, but can't get openocd to play nice! any ideas? Here's a longer version with debugging for openocd:

$ ./openocd -d -s ../tcl -f ./interface/picoprobe.cfg -f ./target/rp2040.cfg -c "program /Users/robert/src/pico/pico-examples/build/blink/blink.elf verify reset exit"

  That's great! Not sure I could have helped on that. :)
  
  OpenOCD is a bit flakey on an M1...that said, the 2 Pico solution for a hardware debugger is awesome. I'm working on some AVR material and there isn't anything remotely comparable.
  
  Thanks for letting me know and GOOD LUCK!

  Thanks Lief - appreciate the feedback - next i want to try out the gdb CLL command and see if I can get that working as well - just a point of clarification - the serial device that you're connecting to is via the USB - does the target RP2040 need the UART connected to the picoprobe RP2040 in order for that serial device to work?
  
  UPDATE: So CLL works great! and you do need the UART of the target connected to the picoprobe UART to access it via the host through the USB connection - great stuff! Thanks again for the writeup!

  Great for you!
  
  As you found out, you’ll need to connect the target 2040 through the probe in order to have serial communications from the target. And CLL is extremely helpful on shortening the compilation/link/load cycle!
  
  You might check out the gab resources page, it’s full of links to gdb debugging. https://wellys.com/posts/gdb_resources/

I tried following this route for my M1 Max install. I've been struggling for a while to nail up this toolchain (Clion for RP2040) and there seem to be more gotchas than seems completely fair....
I got to the

"brew install libtool automake libusb wget pkg-config gcc texinfo"

step above and I see that brew installed everything with the warning that everything was being installed pre-fixed with a "g".
This is new to me. I think it related to a conflict with my Xcode installation.

I wasn't too keen to carry on just in case I really started to make a mess of things.

Am I worrying about nothing? Is this the way to go or has a more up to date guide on this appeared in the meantime?

Thanks in advance to any and all for any guidance and/or pointers that might help.

Hi all - I'm unable to find arm-none-eabi-gdb using Homebrew. It seems from the notes above it should be possible to get this installed. Any pointers to the correct installation method? I'm on an M1 Mac running Monterey. Thanks!

  UPDATED
  
  There is a bug in the ARM GCC compiler on M1 Macs, see UPDATED April 7th, 2022 above.
  
  The rest of this is the journey that got me there...ignore it.
  
  I just did a brew list and it shows gcc-arm-embedded as a Cask. I also did a search on brew.sh and, it didn't show anything for arm-none-eabi-gcc, it does show gcc-arm-embedded.
  
  I also went to the GNU Arm Embedded Toolchain Downloads site and found it was deprecated. When you click on the Arm GNU Toolchain button, it takes you to a new site GNU Toolchain for the Arm Architecture which describes the compiler as gcc...which is probably gcc-arm-embedded.
  
  All of this to say (or confirm) that you need to install gcc-arm-embedded.
  
  Update:
  I removed the old arm-none-eabi-gcc and performed a brew update and brew upgrade, which installed a new version of gcc-arm-embedded. Then I ran cmake .. as described in the entry:
  
  PICO_SDK_PATH is /Users/lkoepsel/Documents/pico/pico-sdk PICO platform is rp2040. -- The C compiler identification is GNU 11.2.1 -- The CXX compiler identification is GNU 11.2.1 -- The ASM compiler identification is GNU -- Found assembler: /opt/homebrew/bin/arm-none-eabi-gcc Using regular optimized debug build (set PICO_DEOPTIMIZED_DEBUG=1 to de-optimize) PICO target board is pico.

  [ 0%] Building C object blink/CMakeFiles/blink.dir/Users/lkoepsel/Documents/pico/pico-sdk/src/rp2_common/pico_platform/platform.c.obj
  
  Killed it and deleted the entire build folder then reran:
  
  mkdir build cd build cmake .. cd blink make -j4
  
  And it appeared to freeze again. My next step is to delete everything and start all over with my instructions. The examples, sdk etc are all over a year old...
  
  Last update: Failure
  
  I was using a new terminal program, switched back to iTerm and re-did all the steps. I am getting the following errors:

  Haven't found a working solution.
  
  Sigh, it appears one of the working solutions is to use an Intel Mac. Just attempted the above instructions on an 2018 MBP and it ran fine.

  Thanks for the updated process - I've got it working with VS Code on my M1 Mac mini. After using your steps above, I just needed to update the paths in the launch.json (from the "Getting Started" manual) for picoprobe.cfg and rp2040.cfg. The relative paths didn't work, so I used the full paths. Then just needed to add the line "cortex-debug.openocdPath" to the settings.json with the path to openocd. From there I'm able to use VS Code's built-in debug tool.
