# Flash RCX 6A with SimonK firmware

## Steps

  $ avrdude -c usbtiny -p m8
  avrdude: AVR device initialized and ready to accept instructions

  Reading | ################################################## | 100% 0.01s

  avrdude: Device signature = 0x1e9307

  avrdude: safemode: Fuses OK (E:FF, H:DF, L:A4)

  avrdude done.  Thank you.

Then, flash firmware

  $ avrdude -c usbtiny -p m8 -U flash:w:./tgy.hex:i
