Installing usbboot on macOS

We’ve had issues with the official instructions at https://github.com/raspberrypi/usbboot

Alternative instructions worked for @napowderly: https://www.jeffgeerling.com/blog/2020/how-flash-raspberry-pi-os-compute-module-4-emmc-usbboot

Device Tree Configuration

Docs: https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README

Configurations are applied in config.txt:

sudo nano /boot/firmware/config.txt

To configure i2c, do something like: dtoverlay=i2c1-pi5,baudrate=400000,pins_10_11 This depends on your hardware and there are separate device tree overlays for different Raspberry Pi models and each peripheral.

NOTE: the flag “pins_10_11” must be placed after the baudrate param. Dunno why, but do it otherwise it’ll not boot.
