inga_tool is a utility to reset the INGA and update the FTDI EEPROM

Building

To build it, you need libudev and lipopt; and either libftdi 0.19 (or later) with libusb 0.1, or libftdi 1.0 (or later) with libusb 1.0. Just typing

$ make

should build the binary. I might add autotools support eventually.

Use it like this to reset an INGA node:

./inga_tool -d /path/to/usb/serial/device -r

The following will flash the EEPROM (WARNING, not extensively tested):

./inga_tool -d /path/to/usb/serial/device -f -v

You can also read out the EEPROM:

./inga_tool -d /path/to/usb/serial/device -s

It is also possible to choose a device based on the USB serial ID:

./inga_tool -u <serial> -r

Reset

This is used to go into the bootloader without the need to reset the device manually. You'll need an up-to-date bootloader for this to work. In addition, flashing the EEPROM of INGA is required before using the reset functionality.

Flashing

Right now no options are supported for flashing, that will be something for the future. The following changes will be made:

• manufacturer -> "IBR"
• product -> "INGA"
• cbus functions are set to

CBUS0 TXLED
CBUS1 RXLED
CBUS2 TXDEN
CBUS3 IOMODE
CBUS4 SLEEP

Unchanged are VID/PID and the serial.

OS X

inga_tool works partly also with OS X. Selecting a device ist only possible with option -u (serial number). It is not possible to unload the FTDI driver for a specific USB-device. Also you need to be a superuser to unload the FTDI driver (Warning: this disconnects all FTDI devices).

But if you need so you can use

sudo kextunload -bundle com.apple.driver.AppleUSBFTDI

to unload the driver and

sudo kextload -bundle com.apple.driver.AppleUSBFTDI

to reactivate the driver after using inga_tool. These changes are only permanent until next reboot.
