I come back with a topic I've tried to solve a while back. So, to start:

And this is what I keep getting.

I have a windows 7 x64, everything else is as per topic.

I've soldered (about 3 times already) a connector to the board. The connections are correct and working (checked for impendance from each atmega pin to the connector pin).

I've tried:

• powering the board through the programmer (5V) and through a lipo.
• -B 100
• testing the programmer on other IC (attiny25-20PU, seemed to read the signature fine (empty, at the moment))
• desoldering the capacitor above the RST solder point
• reading with different switches on (ail d/r, thr cut) - some success here earlier. Since then I've resoldered the connectors and been so far unable to replicate this 'success'. Right now, when I try to repeat it, I get the 0xc9 and after that a switch error on t9xv2. Anyway, to be specific, this "success" looked like this: ================================================== =============================== Started AVRDUDE C:/Program Files/eePe/avrdude.exe -c stk500v2 -p m64 -B 200 -P com1 -U eeprom:r:C:/Users/ONEIRO~1/AppData/Local/Temp/temp.hex:i ================================================== =============================== avrdude.exe: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.08s avrdude.exe: Device signature = 0x000000 avrdude.exe: Yikes!

So far, I've been unable to pinpoint the problem. I'm starting a separate thread, because the conversation around here died. If You've got any ideas, please share them. Thanks!

just a bump. Anybody?
