I’m having trouble with my Serial AVR-JTAG. I’m unable to connect with AVR Studio 4.12 SP3 Build 485. No LED with +5VDC connected to connector. Should I be able to use AVR Studio with an Atmel AVRISP programmer to do a firmware upgrade? I am able to comunicate with the ATMega16 inside the JTAG, read signature and fuses. I’m unsure of how to set the fuses. The fuse settings in Studio aren’t an exact match for the ones in the upgrade article. If I knew the HEX values I could use that to be sure that I had the fuses set correctly.
