I can't bind the /dev/ttyACM0, because my system doesn't have such a device. Is it necessary to mount this device?

It's only necessary if you want to bind it. However, opensesame seems to be a bit useless without it.

Everything except of the air-quality sensors works without it (the other devices/sensors use i2c).
| You need to have the [A20 Debian image](http://images.olimex.com/release/a20/) extracted somewhere in your filesystem. | ||
| This means you either extracted it from the image file, you mounted the image file, or you have already written it onto a microSD card and mounted that on your system. | ||
| As an example, we have extracted the whole image into `/tmp/olimex`. | ||

Maybe you could include some basic information on, how to mount from an Image. For example, extracting the offset of the partition which should be mounted (``fdisk -l .img) and how to setup the loop-device (losetup -o -f .img).

Well I can't because I don't know. But feel free to add suggestions via the comments on how you set up that.

First you need to get the offset of the olimex.img for that you need to execute fdisk -l olimex.img, now you need to get the starting sector of the image partition, you like to mount. Now you have to multiple the starting sector with the sector-size and this results in the offset. In the next step you have to setup the loop-device with losetup -o <offset> -f olimex.img. You can list all you loop-devices with losetup -l, to see on which loop-device your image is connected. The last step is to mount the loop-device with mount /dev/loop0 <mount-dir>.

@fel115 probably easier if you directly write it.

With my image it doesn't worked. I get this error message No suitable root partition found in image 'A20-OLinuXino-bullseye-minimal-20220928-143706.img'.. It think that's because the image doesn't contain a MBR- or GUID-table.
