Overview

sunxi-armbian-flasher-osx is an example application wrapper around sunxi-fel and https://github.com/zador-blood-stained/fel-mass-storage. Important: You always have to ensure that your device enters FEL mode correctly, on some eMMC equipped devices like Orange Pi PC Plus or NanoPi Air this requires flashing the fel-sdboot.img image first and booting the device from it (right/control click on the application bundle, choose 'show package contents' and navigate to Contents/Resources/fel-mass-storage).

It has been made using Platypus and the main parts are contained inside the Resources directory and can also be updated there in place.

The purpose is to FEL boot a sunxi device and then expose either SD card or eMMC as USB Mass Storage device to the host so the sunxi device itself acts as an card/eMMC reader and allows access to either SD card or eMMC. This way you can backup the eMMC contents or flash images directly to SD card or eMMC.

Updating contents:

In case you want to update the fel-mass-storage stuff (eg. a new SoC has been added) simply chdir into the application bundle, then

cd Contents/Resources
rm -rf fel-mass-storage
git clone https://github.com/zador-blood-stained/fel-mass-storage

If a new SoC should be supported you also have to adjust the case construct in the StartFlashing function inside Contents/Resources/script.

In case a newer sunxi-fel binary should be integrated you need to clone https://github.com/linux-sunxi/sunxi-tools and follow the instructions (requires a brew install libusb before). You need to move the new sunxi-fel binary and libusb-1.0.0.dylib into the Resources directory since the app expects it there. Also library paths have to be adjusted if you plan to distribute the application bundle later. Please see here for details how to use XCode's install_name_tool to do this.
