Disable bootsel #2

Closed tadtruex closed 1 year ago

tadtruex commented 1 year ago

Need to disable the Bootsel button so the kids don't accidentally reset the firmware.

Turns out - this isn't going to happen. The circuit uses this button to override SPI_CS for the Flash. There is an example program that jumps through hoops to reclaim the SPI_CS output pin and use it as an input, but only after copying everything to RAM... Seems like a poor choice.

There is a testpoint, so maybe under a scope we can hijack the button, but it will be more expedient to add a new one.

Decided to add a separate reset button.
