Bug 10569

AFT (Automated Flasher Tester - https://github.com/skuusela/AFT) is a tool for deploying and verifying a SW image on an appropriate target HW device. On the other hand, DevAuto is a library package with the purpose to facilitate the control of hardware devices required for creating a fully automated testing service for CI.

In its current form, AFT makes use of a pre-configured Debian image on an USB stick per DUT to allow to boot the device to a known state. From that point onward, the host is able to submit commands to the DUT through SSH in order to copy and flash the target test image to a SD Card on it, to boot from it and finally leave the device ready for testing.

With the objective to be able to flash the target image to the USB stick and install it to the SD Card directly, without requiring the Debian support image, a change on the AFT classes and workflow is required. The modification consists in integrating the DevAuto library and allowing the use of a USB multiplexer to handle the switching of the USB stick between the AFT host and the DUT. This will also provide the benefit of testing the flashing process with an approach that is much more similar to the one final users employ to interact with the device by connecting and disconnecting the USB stick.

Finally, the goal is to implement the described enhancement in addition to the current method AFT uses for flashing in existing setups.
