Hi.
I have some problems with the Arduino as ISP. I can program a Nano, pro mini and leonardo. However it its not possible to programm a mega. With the original sketch (not this) i can upload, it sais "upload finished" but the blink sketch is not running. Burning the bootloader works but i get an error.

So i tried this newer version. But it also seems to have problems with the mega. Here i also get errors. Any idea why this happens or maybe how to fix? I try to port this to the 16u2 as integrated arduino Bootloader, so i need to know if there is a fix possible and where the problem might be located.

I tried with and without capacitor and with slow rates (they dont work at all). I also tried to use a nano as icsp but this also fails.

I'd also recommend to set the SS pin OUTPUT so the user can change the ss pin.

Is there anyone who wants to help me with itegrating this to the 16u2 bootloader? I think its possible in general but maybe not worth it if the mega wont work :( Or someone i can ask for this, more resources pls.
