As many others I have a cheap USBasp programmer bought coming from CN. It's a Fischl clone. But when programming I get the error cannot set sck period. check for usbasp update
I'm using a 2560, means 256Kb flash memory Programms like IDE and Atmel studio are using the programm AVRdude. As mentioned in the documetation of AVRdude. There is an extra note on the 2560. That there is a limited flash programm size of 128Kb. Thus the USBasp programmer won't work with the 2560. Right?
Now my questions:
1) Am i right my USBasp programmer is not for programming the 2560? 2) Who has a USBasp programmer working to programming a 2560? 3) What programmer I need to programming a 2560?
