README refers to INSTALL for building, but the file does not exist

I came here because the openocd that comes with Fedora 43 did not work with rp2350. But there are no clear instructions how to build the project.

Compilation

Just a note that I managed to compile openocd, but with some caveats:

1. Needed to pull and compile jimtcl
2. Needed to apply the following patch to the source tree:

diff --git a/src/Makefile.am b/src/Makefile.am
index 4dbe93fee..5e10aef5a 100644

3. The compilation then worked by:

./bootstrap.sh
./compile --prefix=/usr/local
make -j 20 install 

Uploading blink.elf to the rp2350 through the debug probe

With this new openocd I could then install blink.elf on my Raspberry Pico 2 through the debug probe with the following command:

openocd -f interface/cmsis-dap.cfg -f target/rp2350.cfg -c "adapter speed 5000" -c "program blink.elf verify reset exit"

It looks like this was recently fixed upstream 🙂 openocd-org/openocd@34d76b8

I came here because the openocd that comes with Fedora 43 did not work with rp2350.

Do the pre-compiled binaries in https://github.com/raspberrypi/pico-sdk-tools/releases (which are what https://github.com/raspberrypi/pico-vscode uses) work on Fedora 43 ?

But there are no clear instructions how to build the project.

Our "build instructions" are in https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf

Needed to apply the following patch to the source tree:

Sounds like these are things that you should report upstream. We won't be fixing them in this downstream repo.

OpenOCD doesn't use these libraries. They are jimtcl prerequisites and should be handled by pkgconfig/jimtcl.pc

+++ b/src/helper/command.c

Changes to build with jimtcl 0.84 are the upstream commit
openocd-org/openocd@fe00804

It applies cleanly so I recommend to cherry-pick it
