Raidsonic IB-4220-B.
A gemini-based NAS from Raidsonic.
UART Access
UART location inside the IB-4220-B.
The device comes with a pin header on the board where you can simply connect the UART pins.
See the picture for pin layout.
I have noticed that connecting the PWR pin to the UART converter is not optional input (TX) to the device will not work or the device will not even power on unless you connect the power.
The device uses 19200N8 serial settings.

Kernel TODO
- TBD
OpenWrt TODO
- Fix installation procedure and flash layout.
- Create a ugly kernel module to handle the SSP PWM fan. This just cannot be upstreamed.
