Hi Gokul - Did you update UHD to the same version on both the host computer running OAI as well as the USRP (via the filesystem on the SDcard)? It looks from the GIT commands like you're trying to use UHD 4.0-beta on this new host & you note UHD 3.15 on the USRP ... which won't work. You have to have the same version on both devices. - MLD
