Jan Niehusmann	d4743061fa	Use generic boot loader for rp2040-hal examples ... Those examples should be independent of a specific board. The generic boot loader increases their compatibility.	2022-08-11 11:56:41 +00:00
Jan Niehusmann	44019781e2	Use wfi in otherwise empty infinite loops in examples ... - Clippy warns about empty loops, https://github.com/rust-lang/rust-clippy/issues/6161 - wfi allows to CPU to save some power WFI was avoided in examples for fear of ill interactions with debuggers. However the rp2040 debug port does continue to work, as long as the relevant clocks are not disabled in SLEEP_EN0/SLEEP_EN1. (By default, all clocks stay enabled in sleep mode.) This patch replaces several different workarounds with just calling wfi.	2022-08-01 14:54:03 +00:00
