I am currently on Ubuntu and I am trying to install the latest firmware on this Chameleon Tiny I have.
The error occurring keeps happening and each time the % changes. I have tried different cables and also different ports yet the same error occurs. I am pretty sure that I am putting it into bootloader mode each time I plug it in (I have it unplugged, hold "B" button, plug it in and then let go off "B". The CHG light glows and then un-glows (I think it used to stay glowing until I ran the command but I don't know if it did)). Using python3 ./chamtool.py in the Software folder doesnt seem to recognize that there is any Chameleon plugged in:

finnley@finnley-laptop:~/ChameleonMini/Software$ python3 ./chamtool.py
Use -p COMPORT to specify the communication port (see help).

I have even tried reinstalling avrdude as well but still nothing works. I tried using the "RFID Hacking By Iceman" "chameleon-mini" channel but I did not get many responses so I thought I should ask here

It looks like you tried everything already.

From my experience, different ports/cables are an easy fix (obviously not the case here)
I always use make program to flash it - depending on how I set up my machine this might be neccesary to be run as root

Regarding the communication to the chameleon itself: I look at ls /dev/ttyA* before I connect the Chameleon and again after I connected it to find the tty device (usually ttyACM0 or ttyACM1, depending on how many other devices might be attached) and then use minicom -d /dev/ttyACM0 or whatever devicename you found out to connect.

From there at least version? should give you an answer - which would suggest, that the chameleon is indeed working and connected properly.
