Flashing the firmware

Muca - Firmware

This code is a form from ft5x06-tool, largely inspired from the Focaltech GitHub driver.

Requirements

The source code itself isn't depending on any external library, so no build dependency.

As for runtime dependency, the kernel must have i2c-dev support enabled.

You need to have physical access to the i2c ports, like raspberry pi.

To enable i2c-dev:

sudo raspi-config
5 > Interfacing options
P5 I2C
<Enable>

Wiring

Build instructions

Very straight-forward:

$ git clone https://github.com/muca-board/muca-firmware.git
$ cd muca-firmware/
$ make

Usage

To upload the firmware to the Muca Board (FT5316DME)

$ ./muca-flash -b 1 -c 0x0A -i MuCaFirmware.bin 

On a raspberry pi, the i2c bus is set to 1. The chip id has to be forced because the firmware is empty.

The tool has an help output which lists all the different parameters.
