I've tried to burn the boot loader into a new chip but couldn't get it to work. I tried all of the possible changes and fixes mentioned in this thread but nothing worked.
In the end I uploaded the Yocto boot loader via Arduino as per instructions on the Yocto software thread. This worked and have now been able to upload the latest firmware.

This week, I got new chip and installed nava 1.020 and boot loader via ICSP. its success.woking fine.
its curious case of yours

For some reason, despite changing the com port the cmd would not find a pathway.
However I need to revisit this. My encoder is not working with v.020 so I need to try and reinstall. Works fine with v.018

hi all,
i'm having trouble with my Nava build (
viewtopic.php?f=24&t=1093&start=20). I'm getting voltages all correct but I suspect something up with Atmega at this point.
I've tried flashing using the steps outlined earlier in this thread; every avrdude command line results in this:

Double check connections and try again, or use -F to override

avrdude.exe done. Thank you.
Is my chip at fault here? I've tried with both Arduino Uno directly (ensured pins matched) and also tried using Nava's own power source to no avail.
Any help appreciated!

Okay so I am having issues understanding how to reflash my ATMEGA128 chip that came with 1.024 NAVA OS with the latest update.
I have an arduino UNO, as well as an AVR ISP MKII.
Is it as simple as popping out the atmega chip on the uno, and swapping it with the NAVA atmega, connecting the AVR to the arduino board, and then uploading the appropriate software to the chip via an arduino sketch?
a little confused by all of this.

I am really eager for a fix for this as well.
One of my two Nava's updated successfully but the other would not after dozens of attempts of all different settings and software.
I have an Arduino Uno R3 which I believe can be used as an I(C)SP.
I attempted to follow online directions to use Arduino Uno to burn a new bootloader to the Nava ATMEGA chip on a breadboard,
but I couldn't get it to work.
I could access the chip but couldn't successfully write anything to it,
how to set the fuse bits and accomplish this is not very clear.

The NAVA has an ICSP header next to the 1284p chip. You should connect your avrispmkII to this header but something to note; MISO and MOSI pins are swapped so ensure you flip these. Also, the avrispmkII does NOT provide 5v power to the NAVA so you'll need to still power the device for programming.
