I'm trying to set a Raspberry Pi Zero up as a mobile dev tool.
After a few false starts I have everything set up and I can program an ATTiny85 via SPI and the GPIO pins.
Once - it will flash the program once, and then fail with the error:
avrdude: verification error, first mismatch at byte 0x0000<br /> 0xff != 0x0e<br /> avrdude: verification error; content mismatch
If I reboot the Pi, it will work again, but still only once until another reboot.
All of my avrdude config files are default, I have a 1uF capacitor between GND & VCC, and 10k resistor between VCC and RESET on the ATTiny, calling avrdude with this:
<br /> $ sudo avrdude -P /dev/spidev0.0 -c linuxspi -p t85 -U flash:w:blinky.hex<br />
