tool to automate the programming of microcontrollers

In order for this tool to work, the CBUS pins must be configured as GPIO. This configuration can be achieved by using the tool at ft232_cbus_config which configures all CBUS pins as GPIOs. This configuration, updates internal EEPROM and needs only be performed once on a given FTDI chip.

This application uses libftdi1 and libudev-dev, so these libraries must be installed (and, depending of the distribution, headers too)

apt-get install libftdi1-2 libftdi1-dev libudev-dev

and if not already done, install pkg-config, make and gcc.

To build the app:

$ make

By default, users have no access to converters. A rule file (99-ftdi_cpu_progr.rules) for udev is provided at the root directory of this repository. These rules set access right and group (plugdev) when a converter is plugged.

$ sudo cp 99-ftdi_cpu_prog.rules /etc/udev/rules.d/
$ sudo udevadm control --reload-rules && udevadm trigger # force udev to take new rule
$ sudo usermod -a YourUserName -G plugdev # add user to plugdev group

After that you need to unplug and replug your device.

./ftdi_cpu_prog -b [0-3] [-bd [0-1]] -r [0-3] [-rd [0-1]] -m [0-1] -d device
        -b pin connected to BOOT
        -bd default state for BOOT
        -r pin connected to reset
        -rd default state for reset
        -m mode 0: bootloader, 1: simple reset

For -b and -r args, value must match indexes for CBUSx connected to BOOT and RESET
