Hello Bodhi,
I got Synology DS210j. Let's make it work with Debian.
Hooked up the serial console, and it's different than DS211.
Pins are upfront of the device and are horizontal with markings JMP2, and you need to use to lower three pins:
From the front side perspective lower row: RX(?), TX, GND
From the front side perspective upper row: ???, ???, VCC (3.3V)
I have determined GND and VCC (3.3V) using multimeter.
I can't get it to receive input from the serial console, I tried all pin combinations but to no luck. Any ideas what can be tried?
Interestingly it boots to a linux kernel, although there are no drives hooked up, and it reports only "Flash: 4 MB" (how is it possible to fit?):
