Facing issue regarding data connection with "cm" tool

Legato Linux distribution (Yocto project)
1

Hi,

I have added wifi(RTL188EU) and webCamera driver in kernal image and flashed the mangOH Green board with this image.

Camera is working fine.
But, facing problem with “cm” tool commands
when I give normal command “cm radio”, It does not give reply and stuck in waiting stage.
after giving ctrl+c, it get out of that command.

Even avcService and dataConnectService in Developer studio is get error and stoped working.

When I flashed generic image which downloaded from seirra wireless site, It works fine and
I am able to connect to internet using “cm data connect”
and all sevices are running fine in developer studio.

Can any one tell what is wrong with my board.

Hi @rups,

which version do you originally have on the target (legato version + cat /etc/legato/version) ?

What about after? Is it the same Legato or did you replace it as well?

Hi @CoRfr

cm command problem is solved and internet connection is also running fine.

I dont know exact solution but I flashed image again and given DC power supply to mangOH board as previously I have given it by microUSB.

Thank you!
