Use latest Pico-SDK in raspberrypi platform

[jhmaloney]

After a clean install of the raspberrypi platform, the "pico-sdk" subrepository is in a detached head state at commit b1676c1.

Is it possible for the raspberrypi platform to use a later release of pico-sdk? There was a recent change in the SDK support for the RP2350-B board a few months ago. They removed the PICO_RP2350B #define and now use PICO_RP2350A=0 to indicate RP2350.

Those #defines are used to enable the extra GPIO pins on the PICO_RP2350B. I am porting MicroBlocks to the Sparkfun XRP controller board (an educational robotics board).

As a workaround, would it be safe for me to fast-forward the pico-sdk to the current head? Or might that break something?

Thank you!

Hi @jhmaloney, you're probably reporting a wrong repository as this dev-platform doesn't support Pico SDK.

I'm using Earle Philhower's "arduino pico" framework. I think PlatformIO does support that framework, no? I'm using:

platform = raspberrypi

In any case, that framework include a folder called "pico-sdk". Here is a file list of ".platformio/packages/framework-arduinopico":

ArduinoCore-API cores keywords.txt LICENSE package.json programmers.txt tests
boards.txt docs lib ota pico-sdk README.md tools
boot2 include libraries package platform.txt system variants

The pico-sdk folder is a git subrespository.

You're probably using a fork, not the official PlatformIO development platform for RP2040. The name of the platform in your configuration file will still be the same platform = raspberrypi, but it will point to a different implementation.

In any case, that framework include a folder called "pico-sdk". Here is a file list of ".platformio/packages/framework-arduinopico"

There are two Arduino cores for RP2040, the official one from the Arduino team and a thirdy-party alternative port. This dev-platform only supports the official Arduino core. As I mentioned above, you've previously installed a fork of this dev-platform that has support for alternative frameworks (probably this one from @maxgerhardt). I'm not sure how framework package updates are handled in that fork, but you can ask directly in that repository.

Yes, I'm using the alternative Arduino core maintained by @maxgerhardt. I will ask about this on his repository.

Thanks for pointing me in the right direction.
