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.conf looks the same as Marcell's instructions. <1Ohm from Dsub to AVR pins, everythings matches) avrdude: safemode: Fuses OK avrdude done. Thank you. C:\WinAVR>

this is what I use with linux mknod /dev/parport0 c 99 0 chmod a+rw /dev/parport0 avrdude -p t13 -c bsd -E noreset -e -U flash:w:test.hex AVR db25 reset to pin#7 SCK to pin#8 MOSI to pin#9 MISO to pin#10 gnd to pin#18
- Currently I'm trying this with my relatively new Dell laptop (D600 in docking station). I read somewhere that sometimgs the parallel port pins don't match up to what they need to be (D0, busy, etc). Am I better off with an ancient motherboard and running Linux??
What I've checked:
- Installed giveio.sys, service started
- ISP pins to pins on AVR
- Had a bad solder on the VCC pin of the ISP header. Does this matter?
- VCC/GND to AVR
- check all GND and VCC, there are many. Document your measurements here (include AVR pin number everywhere).
- AVCC (pin 64) - +5V
- VCC (pin 52) - +5V
- VCC (pin 21) - +5V
- < 1 Ohm from each ground pin to ground plane
- 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 ?
- Yes, didnt have a crystal, using a standalone oscillator feeding 16MHz TTL level pulses to XTAL1
- 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...
