How to create FlexiView FV-1 OSK Firmware updates

---

Thanks to work done by Angus Gratton in discovering how to read and write the proprietary .OSK update file format, it's now possible to create your own FV-1 firmware images. The tools for doing this are on GitHub at https://github.com/projectgus/mboot-tools

He has also made great progress with running Debian Linux on this computer. Background and installation info available from the ProjectGus blog at http://projectgus.com/2012/01/mesada-flexiview-fv-1-androidtv-technical-review/ and http://projectgus.com/2012/02/debian-on-flexiview-fv-1/

 

Serial Port Pinout for debugging

---

The FV-1 Android TV debug serial port speed is 115200 and the pin order that is GND, RX, TX, 3.3V - from the point of view of the FV-1 the data goes in on RX and gets sent out by TX.

An STK-500 AVR development board was used to connect to the port as it has a spare RS-232 to TTL level shifter on it.  Pictures of the setup are below.

Here is the serial output from the FV-1 boot sequence:
