Hello Andrea,

I have tried to add the line to my machine config:

IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt"

But this didn't help, then I looked a bit further and also tried to set the following:

USE_DEVFS="0"

VIRTUAL_RUNTIME_dev_manager = "mdev"

Unfortunately this doesn't seem to change anything.

Cheers,

Gerard

Hello Gerard,

if your old kernel lacks devtmpfs you need a "device table".
You need to set at least
IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt"

This is a default set in image.bbclass before and after daisy...dunno
what's happened with this release.

Cheers
Andrea
