Hi,
I got a brand new board and cant easily upload to it.
I tried a FTDI that worked on several other boards. Got error similar to this: avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x20
I tried Arduino as an ISP to see about loading any sketches or bootloaders to know avail.(similar errors)…
I tried the ATMEL AVR ISP programmer and it works!.. but I’d rather work within the Arduino IDE…
Any help? thank you, thomas
The AVRISP mkII works with the Arduino IDE. I use it to program my custom boards. You do need to do some modifications to the IDE. Google “AVRISP mkII arduino IDE.” I believe it’s just adding another option in the boards.txt file.
Like this one under [installdirectory]/hardware/arduino/boards.txt

Hey thanks codlink for the info. Yes, I’ve got my AVRISP mkii working with the Ateml Studio and AVRdude. But that was really hard. Too different drivers… and too many headaches…
I like to see that AVRisp mkii gathering dust as much as possible… but thanks anyways… - thoams
Chris with Sparkfun got back to me and gave me a hex file to program with my avrispmkii in avrdude.
It all worked. Everything works. one small victory.
I’ve attached the booloader hex file sparkfun provided. I’m not sure how it is any different than the one in the Arduino cores: “…\arduino-1.0.5-r2\hardware\arduino\bootloaders\atmega\ATmegaBOOT_168_atmega328_pro_8MHz.hex”
well sorry… they wont let me attach it…
Here’s what it looks like in Avrdude:
Here’s the tutorial I always go back to: http://www.ladyada.net/learn/avr/avrdude.html
