We have been informed there is a very simply way to upgrade your FTDI module firmware.
This process is currently undocumented in the FTDI manual. All you do is save a particular file onto your USB drive and insert it into the module! There is no need to open the module or change any jumper settings.
Step by Step:
1) Contact FTDI technical support (support2 AT ftdichip DOT com)
2) Politely request this file by email:
for VDRIVE2 - ftrfb_main_3_55VDPAB.ftd
for VMUSIC2 - ftrfb_main_3_55VMSC1B.ftd
Note these files are not the same as the ROM files on the FTDI website.
3) Rename the appropriate file to ftrfb.ftd and copy onto your thumb drive. The filename must be exactly as shown.
4) Optional - download the program below into the 28X1. This allows you to see the firmware upgrade procedure messages via SERTXD commands as they occur.
5) Power up the system/FTDI module
6) Insert the thumbdrive. The update is then automatically stated when the module finds the ftrfb.ftd file.
7) After update is over, remember to delete the ftrfb.ftd file from your thumb drive
This process will allow any user with one of the modules to easily upgrade without having to build any additional hardware.
