I have just bought a Programmer v2.1, I have some ATmega328PBs to program with the bootloader within the Arduino IDE.
I have installed the Arduino IDE and driver support for A-Star but when I try to upload the bootloader I get an error;
avrdude: stk500v2_command(): command failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
Error while burning bootloader.
As a test I connected the V2.1 to a standard UNO using AVRdudess, selecting STK500 and the correct com port. The v2.1 programmer will not read the ATmega328 at all. A clone STK500 works as expected with the same UNO.
The programmer coinfiguration utility sees the v2.1 and you can set it up. The serial uploader works too.
Windows 7 64bit.
Any ideas what the problem might be ?
