Unable to use AVR-ISP-MKII via avrdude or Atmel Studio 7
« on: August 31, 2017, 06:54:18 PM »
Hello everybody!
I read a lot of threads regarding the issue that many people (like me) find in using AVR-ISP-MKII.
So far I had no luck on getting it to work.
This is the situation, starting with avrdude:
- the firmware on AVR-ISP-MKII has been upgraded to the latest one
- the drivers are correctly reported as libusb
- I'm running Windows 7 64bit
- I tried both avrdude 6.3 and 5.1.1
- I'm trying to flash an atxmega128a1u-au

Latest test has been made with the following:
Code: [Select]
avrdude -p x128a1 -P usb -c avrispmkii -F -U flash:w:ensemble-CH-3044.hexand this is the result:
Code: [Select]
avrdude: stk500v2_command(): error in CMD_XPROG: Failed
avrdude: stk600_xprog_program_enable(): XPRG_CMD_ENTER_PROGMODE failed
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x000000
avrdude: Yikes!  Invalid device signature.
avrdude: Expected signature for ATXMEGA128A1 is 1E 97 4C
avrdude: NOTE: FLASH memory has been specified, an erase cycle will be performed

         To disable this feature, specify the -D option.

avrdude done.  Thank you.

Do you guys have a suggestion for me?
Thank you!

This is not an issue with the drivers since AVR-ISP-MK2 is properly recognized. It is probably improper hardware connection between AVR-ISP-MKII an atxmega128a1u or lack of power supply. It can be wrongfully set configuration bits, make sure to test with another x128a1 chip if possible (sometimes source of clock is wrongfully set).
