# W5500-EVB-Pico2 doesn't reboot after flashing MicroPython

## Question

Asked by Juergen on 2024-10-27 in MCU & Boards.

Hi all,
My brandnew W5500-EVB-Pico2 doesn't reboot after flashing MicroPython.
I can enter the flash mode and copy the W5500_EVB_PICO-20241025-v1.24.0.uf2 file to the W5500-EVB-Pico2. But it doesn't reboot.
I've tested the same W5500_EVB_PICO-20241025-v1.24.0.uf2 file with a RPi Pico W and the RPi Pico W reboots. I can also connect to the board with Thonny. So the W5500_EVB_PICO-20241025-v1.24.0.uf2 file must be ok.

Does anybody has the same issue or can provide a solution?
Thank you very much in advance.
Best regards,

Juergen

I'''ve performed all the steps described. The issue still exists.
Another brandnew board shows the same issue. The board revison Rev 1.0

Flashing flash_nuke.uf2 lets the W5500-EVB-Pico2 reboot.

Solved:
Currently there is no MicryPython version available for the W5500-EVB-Pico2.
W5500_EVB_PICO-20241025-v1.24.0.uf2 works only with the W5500-EVB-Pico board.
See <https://maker.wiznet.io/forum/15339> for details

There’s a pull request on MicroPython’s GitHub to add support for the W5500-EVB-Pico2 and W5100S-EVB-Pico2. Check it out here: https://github.com/micropython/micropython/pull/16280

I've made a firmware, see thread: <https://maker.wiznet.io/forum/15529>

The .uf2 file W5500_EVB_PICO-20241025-v1.24.0.uf2 was built for the PICO (RP2040) and is likely not compatible with the PICO2 (RP2350).

Expected Issue: Differences between RP2040 and RP2350 The PICO2 uses the RP2350, but the current MicroPython firmware was likely built targeting RP2040.
Since the RP2350 has some hardware differences from the RP2040, a .uf2 file built for the RP2040 may not run properly on the RP2350.

Therefore, I recommend testing the firmware on an RP2040 board first to confirm that it boots properly. If it does, then this firmware is not compatible with the PICO2.

Regards.
