[yocto] rootfs mounted read-only on Live USB (x86-64)

[Oleksandr Poznyak]

Hi,

Check if "read-only-rootfs" feature is added to any of these variables
either in your local.conf or your image bitbake recipe:

Something like that:

IMAGE_FEATURES = "read-only-rootfs"

EXTRA_IMAGE_FEATURES += "read-only-rootfs"

Thanks,
Oleksandr Poznyak!
