Can't get my Genboard v2.2 working...
Using Marcell's programming instructions from: http://www.x-dsl.hu/genboard/programmer.txt
Currently my cable is wired as an STK200:\nÿ1ÿ
AVRDude reports:
\n
C:\WinAVR>avrdude -c stk200 -p m128 -F avrdude: AVR device not responding avrdude: initialization failed, rc=-1 avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.00s avrdude: Device signature = 0xffffff avrdude: Yikes! Invalid device signature. Check stk200 entry in avrdude.conf and measure from end-to-end (parallel DSUB25 to AVR pin), and extend the table above with AVR pin number. avrdude: safemode: Fuses OK avrdude done. Thank you. C:\WinAVR>
What I've checked:
- Installed giveio.sys, service started
- ISP pins to pins on AVR
- VCC/GND to AVR
- check all GND and VCC, there are many. Document your measurements here (include AVR pin number everywhere).
- Clock signal on XTAL pins
- what does it mean ? The clock is oscillating with 16 MHz ?
What's next? I can scope it if necessary, just don't know what I'm looking for...
