Installation

After unlocking the bootloader (simply enable developer options and enable OEM unlocking), refer to Installation/Using a pre-built image or Installation/Using pmbootstrap and #Flashing.

Using Heimdall, flash boot.img onto KERNEL and the other image onto either SYSTEM or USER, though it's highly recommended to install to USER as it has much more space than SYSTEM (~5.2GB versus ~1.8GB).

Pre-built Sxmo images are available here: edge (recommended), v24.06.

If you wish to use the downstream port for whatever reason, you can do so by choosing coreprimevelte-downstream as the device.

Mainline

As of pmaports!4540 mainline is used by default when selecting the device in pmbootstrap. So far, there's only a DTS for rev02 (out of rev00 and rev01), but the rest seem to be identical with the difference that one pin is in a different pinctrl group.

An U-Boot port is planned.

Flashing

The device can be put in flashing mode by powering it on while pressing the POWER + HOME + VOLUME DOWN buttons simultaneously, and answering the appearing question by pressing VOLUME UP.

Flashing via recovery zip works.

UART

UART over the microUSB connector can be enabled by putting a 150k or 619k resistor between the ID and GND pins. The device TX will be on the D- pin, and RX will be on the D+ pin. A 619k will power on the device as soon as the UART cable is connected, while a 150K won't. Signal level is 1.8V.
