I'm trying to use STK600 with STK600-RCUC3C2-40, STK600TQFP64-2 and a AT32UC3C2512C-A2UT processor, all parts new. I can program the processor with STK600, no debug function in STK600. But when I connect my JTAGICE mkII to processor JTAG port the AVR sturio 5 can not program the processor and the debug do not work, no "contact". The enclosed STK600-ATMEGA2560 from STK600 kit works perfect with the JTAGICE mkII. I can not find any info regarding this problem. Is there some settings that I have missed. anyone ho knows how to solve this or is the parts defect?
