how to mount the UBI image in Ubuntu. plz

Question

How are you?

I'm writing to ask you about how to mount the UBI image in Ubuntu.

First, the image was dumped in the chip-off method.

And I tried to mount the image by extracting only the UBI area from it, but the following error message was output. enter image description here

enter image description here On the other hand, when the image was dumped in the UART method, the UBI.bin area was mounted in Ubuntu, and the result was good.

By any chance, is the chip-off method wrong with mounting the image?

When I mounted the chip-off method, I chose two options. ('include sapre area', skip blank')

Was I doing it right?

Thanks!
