I was lucky enough to get my hands on a second-hand Chameleon v2 sometime last year. I fiddled around with it a few times, only using the C64-Core in standalone mode. Then I stuck it in the closet for far too long.
Last weekend I decided it was time for a little nostalgia.
I flashed the newest firmware (Beta-9p) using Chaco on Windows 10 and finally tried to flash some additional cores to it. I went for the Vic20 Core that was linked in the wiki, flashed it in slot1, inserted a freshly formated SD-Card afterwards, lanched the core aaaaaaand....nothing!
The Monitor went black, the green and red leds on the chameleon stayed on, that was it. I restarted the device a few times. NOTHING, the monitor stayed dark!
I instantly tried to reflash the core but then discovered that no version of Chaco (I tried several) could connect to the Chameleon anymore. Chacocmd says "USB initialization failed" and the Chaco-GUI-Version just gives me "ERROR: No Chameleon found on Bus".
I think by now I tried the most obvious fixed mentioned in the manual.
- disconected everything that was not necessary
- restarted countless times (also with all mentioned buttons pressed - individually of course - on the keyboard and chameleon itself)
- Chaco and Chacocmd in different versions 3 diffent machines (Windows and Linux)
- tried different monitors, cables and power supply....
Nothing,....and I'm ready to throw in the towel. The last thing I stumbled upon in the manual was the section about reflashing the microcontroller on the board, which I haven't tried because it mentions something about a necessary hex-file. Could that be the solution?
I would highly appreciate if someone could share some advice. I really don't know where I went wrong and would absolutely hate to throw my chameleon out.
