Thy for the answers! This gives me a better impression.
I am using the Arduino IDE for everything. I select the mega, Arduino as ISP and burn bootloader or upload via Programmer.
I am still a bit confused. If the v1 cannot burn the bootloader to the right place, why does it still work?
Or maybe the sketch is actually v2 compatible?
Here is the AVR Dude error (with IDE up to 1.5.6):
avrdude: verification error, first mismatch at byte 0x1e000
0xff != 0x0d
avrdude: verification error; content mismatch
With IDE 1.5.7 i can burn the Bootloader sucessfull and very fast!!! Thx for this hint!
The normal uploading is still successfull but the sketch doesnt start!
So how can we fix normal sketch uploading? Still confused about v1 and v2 and why burning still works.
The 100nF capacitor isnt needed i think. I know the 16u2 bootloader source and it seems the uploading doesnt trigger the DTR line. Maybe thats new and the documentation is old?
