The PR has been tested on SparkFun, ILabs, and Pico 2 RP2350 boards. Everything is working except for:

OTA (I need to understand the new boot setup much better)
FreeRTOS (An RPI port exists but is not part of the upstream tree we use and a manual merge will be needed)
HSTX not made into a library (TBD in future release)
RP2350 optimizations (SHA256, others. Will be added at some point in the future once other stuff working)

(Also, for some reason the one official Pico2 that I have tried OpenOCD on has failed, but the same config works fine on the iLabs RP2350 BConnect so it's either some HW lockout on my sample or a wiring issue on the Pico2 board rev 2624 6.17)

Looks like the MINGW on GitHub Actions is now producing applications which don't run outside of MinGW. Windows picotool builds. Will look into it later, but for now only Mac and Linux can build RP2040 and RP2350 w/the new toolchain.

I've got my hands on a couple of the RP2350 boards from Sparkfun (https://www.sparkfun.com/products/24870)
Happy to test if you have any specific requests while you're waiting for your own boards to come in.

Thanks, @zjwhitehead. No rush just yet.

At this stage, it's more proof of life than actual tests. If you have a Mac or run Linux and can use the git repo, you could try a very simple sketch that prints out out the serial port, like

void setup () {
Int I = 0;
while (1) { Serial.println(I++); delay(100); }
}
void loop () {}

There's a good chance it won't do anything, but maybe we'll be lucky. Worst case, you can reinstall MicroPython...

Things like the extra PIO or the flash access(filesystems, eeprom) aren't there yet and really need a board in hand to work on. There's a lot of infrastructure that needs to be there before that fine a refinement...

I tried a simple Hello World with and without the changes I suggested, it builds but after flashing it just puts me back in the bootloader, so there's probably more changes needed.
