When I run make -C examples/blinky build flash monitor

It seems to fail at some point with a SHA-256 comparison failed error:

And the LED isn't blinking. Anything I could try?

You need to attach an external LED to pin LED1 which is pin 1, to see the blinking. In order to use a built-in RGB LED, please use another example, c3ws2812.

The SHA error you could just ignore.

Ah thanks!! Indeed example c3ws2812 works as expected!
