Pine64 RockPro64

Tow-Boot

We highly suggest installing Tow-Boot to the SPI Flash.

• https://github.com/Tow-Boot/Tow-Boot

Having the firmware installed to SPI makes the device act basically like a normal computer. No need for weird incantations to setup the platform boot firmware.

Alternatively, starting from the Tow-Boot disk image on eMMC is easier to deal with and understand than having to deal with U-Boot manually.
