Disassembly
The device can be easily disassembled by removing the four rubber feet and by unscrewing the four screws underneath them. The board is held in place by additional two black screws. Note: The board is connected to the main body with a cable.
UART
A serial console can be connected to the RockBox to retrieve the UART boot logs. A device such as a USB to TTL converter can be used to connect the RockBox. Simply set the USB device to 3.3 volts and connect GND to the GND connector on the mainboard, RTX to TX and TXD to RX. The fourth unlabelled contact on the mainboard should not be connected. Note: Unlike the ROCKPro64, connecting TXD does not prevent the device from booting up.
Connect the USB device to the PC and use a tool such as screen to display the serial output:
screen /dev/ttyUSB0 1500000
Then power up the RockBox and enjoy the serial output on the PC.
