Issue: W55RP20-EVB-PICO Firmware Not Booting After Building

[howie1989]

Hi,

I'm encountering an issue when building and flashing the firmware for the W55RP20-EVB-PICO board using this repository. After running the command:

make BOARD=W55RP20_EVB_PICO -j 4

in the /WIZnet-ioNIC-micropython/ports/rp2/ directory, the firmware.uf2 file is successfully generated. However, after flashing the board with this file, the board fails to boot up.

Details:

The WIZnet-PICO-C repository has a patch (0001_pico_sdk_clocks.patch) that addresses similar issues but requires Pico-SDK 2.0.0. The version of Pico-SDK used in this repository is 1.5.0, which lacks the necessary files required by the patch.
This creates a challenge since the Pico-SDK 1.5.0 does not support the same clock initialization changes needed to make the board work correctly.

Potential Solutions:

Update this repository to use Pico-SDK 2.0.0 to be compatible with the existing patches.
Provide a new patch that works with Pico-SDK 1.5.0 to address the clock initialization issue.

Additional Information:

Flashing the official Raspberry Pi Pico MicroPython UF2 file allows the board to boot up properly, but it lacks the necessary modules (e.g., network) to support the intended use of the board.

I believe an update to either the SDK version or a new patch for SDK 1.5.0 could resolve this issue. Let me know if I can provide further information or help with testing.

Thank you!

@howie1989 Interesting observation, have you create the defect in the micropython port for w55rp20? I believe this repo is for the C examples using VS Code but maybe I am wrong.
Are you still not able to run the example using micropython?
