What is Tow-Boot you ask?
And does it have features I want?
Well according to the Tow-Boot homepage:
Tow-Boot a user-friendly, opinionated distribution of U-Boot, where there is as few differences in features possible between boards, and a “familiar” user interface for an early boot process tool.
The goal of Tow-Boot is to make booting boring.
Features
With regard to features there is one notable feature.
It supports holding the volume buttons during boot to change the boot device!
- Volume UP: Mount/export the eMMC as a mass storage device over USB
- Volume DOWN: Boot from the uSD card instead of the eMMC
The mass storage seems a bit slow (I only got a read speed of 8MB/s) but it is still a handy feature non the less.
Installation
There are currently no pre-build binary on the release pages, but this pull request has installer images.
