Bricked Nano after failed firmware upgrade with 5v FTDI?

[stewlovi...@gmail.com]

I tried updating firmware to the latest, but I confess I used a 5v FTDI cable.

Xloader started the upload, failed. Nano now powers on, but the display is blank. Blue LED still lights, clicks sound, SD card interface blinks blue periodically, GPS blinks. No data is being logged to the card.

Since the 5v mistake I bought a 3.3v only FTDI from Sparkfun, and reattempted the upload. It flashes the red & green lights for a bit, then fails.

Have I fried the FIO? Suggestions?

Try to upload blink or hello world example from Arduino IDE  and see if that works..

a "Hello World" program uploaded from the Arduino IDE works. I can see output on the serial line. So perhaps not all is lost.

In the Arduino IDE I used the following settings:

Board: "Arduino Pro or Pro Mini (3.3v, 8MHz) w/ ATmega328"
Programmer: "AVRISP mkii"

Xloader still fails for me using either of the ATmega328 selectable options, the upload goes for a bit then fails. I am running under Windows; perhaps this is an uncommon environment for Geigie development - are you guys all Mac?

Do I need to go all the way and make a dev environment in the Arduino IDE, or is there another way to upload the .hex file?

Did a bit more of my homework and got an avrdude command line for the upload going. Here's the result:

All help appreciated.

I may not have been clear with my last post -- I still cannot get the upload to work. The verification step is failing in avrdude.

Maybe you Hex file is corrupt.

Download again.

seems to indicate can not upload the file.

I just went and tried the whole process on my wife's Mac with the Mac uploader. Worked just fine on the first try, using the same cable.

Then I went back to my PC and had a second look at my .hex file. And you were right Rob - I had the HTML result of the view for the .hex file saved, not the actual .hex file. I don't know why github makes it so damned difficult to download a single file from their web interface.

Once I downloaded the proper .hex file I could repeat a successful flash using my avrdude command line on the PC. (I had to download the entire project to get to it, I'm not finding any link here https://github.com/Safecast/bGeigieNanoKit/blob/master/bGeigieNano.hex to download it directly). I'm sure Xloader would work too.

Anyhow, Nano #2172 is back online, with 1.3.5.

Thanks for the help!
