AVR Commands

The AVR controls the hardware of the Kurobox, such as the power button and LEDs. It is connected to /dev/ttyS1. To control the hardware, send commands to it.

When you push the power button or initialize button, a corresponding command is send to the AVR by the ppc_uartd daemon.

See here for a description on how to run the kurobox without ppc_uartd

Sending commands to the AVR

To send commands to the AVR,

linkstation # echo -n "commands" > /dev/ttyS1
