Hello everyone,

I recently purchased the Retro Chip Tester (http://8bit-museum.de) which comes with a ATmega2560 chip that needs to be programmed. I bought the XSP Arduino Programmer and although at first I could not figure out the XSP. I couldn't figure out how to even get the XSP in to ISP mode, however, I did figure it out so first checkmark. I tried running the bat file supplied by the retro chip tester creator and was getting timeout errors. Found this site and it's description for the XSP. I was able to no longer get timeout errors but now I'm getting the follow:

avrdude.exe: stk500_program_enable(): protocol error, expect=0x14, resp=0x11

I contacted the RCT creator and he suggest that instead of using "-c stk500v1" to use "-c avrisp" but no change. Same protocol error. Here is the full command I'm trying to use from the RCT manual:

avrdude.exe -C "avrdude.conf" -v -p atmega2560 -c avrisp -P COM5 -U lfuse:r:-:i -U hfuse:r:-:i -U efuse:r:-:i

That command is suppose to check the fuses. I've tried Google search but the few protocol error results I get are all dated as far back as 2004. Anyway, since DFRobot is the only site I have found with actual details for the XSP, I figure this forum would be the best place in seeking help.

Thanks in advance and hope you all have a great day.

Andrew
