Installation

Install to SD card through the standard procedure:

$ pmbootstrap install --sdcard=/dev/mmcblkX

replacing mmcblkX with your target card

OS porting

Some user-space services are currently needed for proper power manager, unless you want to physically shut it down *after* shutting it down in software. These include a cutoff script, and a MCU proxy, which are not currently in the postmarketOS port. See OS porting guide for more information

CutiePi Shell

An add-on to environments like Pixel, adds an UI overlay for mobile-friendliness and a software keyboard. This needs to be packaged as an interface separately.

MCU reflashing

It is recommended to keep the MCU firmware up to date for better power management. This needs to be done via a STlink v2, after disassembling the back panel.
