AVR Commands
The AVR controls the hardware such as power button and LED of the Kurobox. 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 with by the ppc_uartd.
Sending commands to the AVR
To send commands to the AVR,
linkstation # echo -n "commands" > /dev/ttyS1
| Command | Resp | Comments |
| \30\30\30\30 | ? | Send by /www/script/melsub_diskcheck.sh |
| [[[[ | OK | POWER LED blinks slowly. |
| ]]]] | OK | A cooling fan begins high-speed rotation. |
| \\\\ | OK | A cooling fan begins low-speed rotation. |
| >>>> | ? | ppc_uartd sends them on boot. |
| AAAA | ? | ppc_uartd sends them on boot. |
| CCCC | OK | reboot send them before shutdown -r now / reboot. |
| EEEE | OK | shutdown send them before shutdown -h now. |
| FFFF | ? | ppc_uartd sends them on boot. |
