I am using Yocto Sumo version.

The kernel boots up on yocto setup but there is no /dev/utp device node in the rootfs.

1. what kernel configuration need to be done inorder to create "/dev/utp" at boot up?

2. Also what is the major minor numbers of /dev/utp device node.

i am trying "uuc /dev/utp" which is not working.

3. Also the MFG tool on windows gets disconnected on kernel boot up on the yocto setup.

Is this expected behavior before launching uuc /dev/utp?


Thank you,
