RP2040 stops working when hardware SPI in use

[piotrva]

The problem

After the latest update to 2023.6.4 (incorporating #4478) with usage of:

• display/waveshare_epaper/2.90inv2
• spi-bus

The module with configuration as included, after the update did not connect again. The same result was when forcing Pico into UF2 bootloader and uploading the same firmware.

Finally forcing the SPI to software by using force_sw: true provided a workaround and device started working normally.

I'm surprised that works at all. Your on_boot priority is higher than the display, so it won't be initialized yet.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

Well, this was working without any issues with software SPI. So only point of change is hardware SPI.
