Using latest AVR Studio 4.11.

I cannot program the fuses in parallel mode! I had to hook it up serially to set my OSC selection fuses. I can however program lock bits, verify signature, program flash/eeprom, etc.. I just can't set the fuses!

Any ideas? I tried lower voltages, higher voltage. Once I set my FUSEs serially, I could use the device in parallel to program the flash, erase, etc..

Regards

yesterday i have sent a post under the title 'i can erase but...'. i can't even do isp for m128 and at90s8515. the default settings on the board are as they should be.
well i today i tried to do high voltage parallel programming. somehow i am able to program the chip both m12 and at90s8515.(:? does this mean something wrong with isp?)
so i thought of reprogramming the fuse by this way in case i have accidentally disturb the fuse setting before the problem started. but i can't program the fuse. do you think we are in the same boat? i am using the avr studio 4.11 also.
because basically i don't know what is the matter the stk. i'm running out of time!

Initially I also had a problem reading flash,eeprom from devices using the newest AVR Studio in Parallel mode. The problem I figured out was their default selection of the "ISP Freq". This option is found in the "Board" menu of the STK500 programming software.

Set this frequency to a low setting, then slowly increase it if this fixes your problem.

really! thank you a lot! so far so good. however i didn't increase the isp freq just yet. i just lower the freq. once and it worked. i can do isp. after this i will slowly increase the freq. just to confirm if this the prob. thank you again! :D

Glad I could help you! I think Atmel is the only one who can help me though. This is a bug on their end.

Atmel or anyone who knows the insides of the STK500.

What's the problem here?
