Hi Artem!!!

Err, sorry, I confused you because in my reply I used UBI _volume_ nodes, not UBI device nodes.

/dev/ubiX are UBI device nodes.
/dev/ubiX_Y are UBI volume nodes - volume Y on device X.

So I think when you successfully create the volume, you'll get the volume device.

But you got it right, judging from your response.

It should be character device, not block device, i.e. use

mknod /dev/ubi0 c 253 0

Just pushed a fix which makes ubi utilities to be more verbose about errors.
