HI,

I just tried to update my datalogger using file ftrfb.fdt which i got from http://www.ftdichip.com/Firmware/Precompiled.htm but i dont think it worked.
now nothing seems to work, no lights come on. cant communicate with it :S
is there some way to fix this????

thanks
si

PS any quick reply will be very appreciated and will earn many good karma points!

Did you get the correct file and follow the instructions here?http://www.ftdichip.com/Firmware/Precompiled/UM_VinculumFirmware_V205.pdf

I believe so, I downloaded vdap disc and peripheral v3.68, reflash (ftd).
i renamed it then put out on usb. Plugged it in, switched it on then...nothing!
Have I somehow fried it? How would I go about the other method mentioned in the pdf?

Thanks again

OK, so its not working

Could someone do me a great big favour and test this code (or help me where it has gone wrong)
It is based on code talked about in these forums:

Hi, was the data logger working before the firmware upgrade, what was the reason for the upgrade.

An upgrade can be done, as you probably know, by copying a file to a memory module and placing it in the drive or alternatively making a hardware connection and using a PC utility to upgrade the firmware. If the firmware was not right and your datalogger will not read from a memory module then you may have to go the PC utility route to recover. Most memory modules have an led to indicate read and write activity, if you plug in a memory module do you see any activity on the led. Try powering up the logger with a module inserted and look for led activity.

Hi,
Yes the Data logger was working, i upgraded to get the latest firmware as suggested in previous forums.
Nothing seems to work, none of the LED light up. I tried to downgrade the firmware via USB but to no avail!

I'm afraid if you can't load a different firmware version using a USB memory module then the only feasible alternative would be to upgrade via UART as described in this ap note http://www.ftdichip.com/Support/Documents/AppNotes/AN_159%20Vinculum-II%20Firmware%20Flash%20Programming.pdf

Section 4 describes the procedure and at minimum you would need the TTL 3.3v UART cable.

You may or may not think it is worth the trouble to buy a cable, and even then you don't know for sure whether that will fix the problem.

If it were me I would buy the cable ( I actually have one ), they run around the $20 mark. If you fix your datalogger you will feel it was worthwhile and you will have learnt by it. If you don't fix the datalogger the cable is still a good tool to own ( USB to 3.3v serial ) and again you will learn by it although the feeling might not be the same as fixing it, but I would bet there is nobody on this forum that hasn't accidently rendered some piece of electronic device useless.
