ad9361, digital tuning error on linux

Category: Hardware
Product Number: ad9361

A riddle from Jacques Fresco.
This error occurs. When I use NO-OS, there is no such error.

  • Please do not use arbitrary branches or mix and match them. If you are using forks of the ADI repos from someone else, we cannot provide support for them.

    Please use the latest release branches, hdl_2021_r2 for HDL and 2021_r2 for Linux.

    Can you also tell us specifically what hardware you are using? Are you using an FMComms3 card, a custom board, or a SOM?
