atmega 2560

Hi All
I have two Questions 1) I have a few 2560 chips lying around, I managed to upload the boot loader using Atmega chip programmer by Nick Gammon . I must it works realy well. The problem is I can not load any sketches using another Atmega board loaded with the isp program ? Does not even pick up the com port.

  1. Can any one tell me if the amtel Ice programmer will work with the Arduino Ide?

Thank nyou

Once an AVR chip is bootloaded you can program it through serial port 0.

I assume that your 2560 chips are mounted on boards?
The chips won't plug into breadboards, they're surface mount.

Hi thanks for the reply, Yes I have build a small pcb board for these,
The boot loader part went well, but the uploading is a problrm

I think the problem might be that the ATmega2560 requires the newer STK500V2 protocol to support the larger memory size and the ArduinoISP sketch only supports STK500. I'd invest in a USBasp or USBtinyISP from eBay. The USBasp is sold for as low as $2 but it usually only comes with a 10-pin cable so you might want to invest an additional $0.99 for a 10-pin to 6-pin adapter. The USBtinyISP is typically about $5 but often comes with the 6-pin cable. Order now because either will probably take two weeks or more to arrive from China or Hong Kong.
