Hi Simba7,
How good are you with electronics? I believe there’s a uart port on the board but I’m more of a software guy so I can’t confirm…
I have a similar thread but it’s getting nowhere

- /dev/sdb is a “hidden” partition on the disk. It’s using sectors at the end of the drive. Even if you hookup the disk to your computer and repartition it to use the whole disk, you will find that the drive has less sectors and /dev/sdb will show up with no partition.
2 & 4. I’m thinking it uses uboot and the 4 pins on the top side of the board (what I’m calling the side that faces away from hard disk) is a uart/serial.
- I haven’t tried it yet. I will try it later with an SD card… I do know that it supports ext3 (/dev/sdb1 filesystem) but the only formating tools on the device are
mkfs.bfs
mkfs.minix
