require an update of docs in regards to

• update toolchain link downloads for the new version
• how to activate stack protector

require an update of the builder script in regards to

• correctly linking against -lstdc++ or -lstdc++-exc depending on whether exceptions are enabled (-fexceptions found in build flags)

(reminder for me later)

Argh, sorry for breaking your build. I need to do a Platform.IO job as part of CI. :(

[maxgerhardt]

Pretty sure it did not break the build (e.g., -lstdc++ is sitll linked against), we just need to expose the new features to PlatformIO projects too by expanding the builder script.

Hi @maxgerhardt and @earlephilhower,

We have received 35 packages for review in the PlatformIO registry. What is the further fate of these packages?

platformio/platform-raspberrypi#13 - Could you provide a PR with support for this core?

Thanks!

[maxgerhardt]

Ideally we'd want to have the pico-toolchain, Raspberrypi's tool-openocd version and framework-arduinopico in the registry, then I can reference stable versions in https://github.com/maxgerhardt/platform-raspberrypi and create the PR.

[ivankravets]

All packages are approved => https://registry.platformio.org/search?q=owner%3Aearlephilhower&t=tool

Please tell us which packages are not required, we will remove them to keep the registry clean.

Do we need a custom ARM toolchain and OpenOCD?

[maxgerhardt]

Hmm I think I had problems with the tool-openocd-raspberrypi version tha PlatformIO had (1 year old) when trying PicoProbe etc. support, so a newer build is needed, as provided by https://github.com/earlephilhower/pico-quick-toolchain/releases.

And as far as I understand it, this core builds on custom configuration + features of the ARM toolchain, e.g. with exception code etc. (linking against stdc++-exc if exceptions are enabled etc), see e.g. here.

All packages are approved

Great, I'll see if I can work with that. As detailed in this issue, we probably need a small builder script fixup and release 2.0.4 to get full / equal build options support with the Arduino IDE.

Thanks for the provided information. We would be thankful for the PR. I've just done a quick look at your fork and it looks good. The only note is to use env.Exit(1) in SCons scripts where you need to stop the building process.

@ivankravets PR created for platform-raspberrypi per above, PR for PlatformIO docs and here builder script + doc update here will follow.
