Flashing the FTDI EEPROM under linux

The very first batch of boards (5) have an FTDI EEPROM that doesn't seem to work under linux properly.

I discovered that libftdi comes with a couple utilities that can read and write the FTDI EEPROM.

I cloned this repository and followed the build instructions here.

When I did the make, it failed part way through, but it was after it had built the ftdi_eeprom utility, so I never bothered to investigate the build failure.

You should find build/ftdi_eeprom/ftdi_eeprom.

You can read the EEPROM by doing (assumes you're in the build directory):

cd ftdi_eeprom
wget wget https://raw.githubusercontent.com/mozilla-sensorweb/sensorweb-wiki/master/jtag-eeprom.conf
sudo modprobe -r ftdi_sio
./ftdi_eeprom --read-eeprom jtag-eeprom.conf

and then you can update the EEPROM by doing:

./ftdi_eeprom --flash-eeprom jtag-eeprom.conf

After updating the EEPROM, you should unplug and replug the board.
