Created December 16, 2020 19:30
Update RPi boot SSD after kernel update
#!/bin/bash
# (This isn't really a shell script - you can't run 'sudo' in a script, I don't think.)
#
# Boot/kernel problems 19/Oct/2020
# (On pi3, which boots from SD card, but then mounts the SSD to /boot,
# resulting in the wrong partition gettting updated.)

getLine for RPi Pico, in C (based on https://github.com/ambotaku/pico-getLine)
// Adapted from https://github.com/ambotaku/pico-getLine
// Trivial code change to allow compiling with plain C on Pico.
//
const uint startLineLength = 8; // the linebuffer will automatically grow for longer lines
const char eof = 255; // EOF in stdio.h -is -1, but getchar returns int 255 to avoid blocking
/*
* read a line of any length from stdio (grows)
*
* @param fullDuplex input will echo on entry (terminal mode) when false
* @param linebreak "\r" may be needed for terminals
