[USRP-users] Compatibility number mismatch between a custom FPGA image and host code

The compat number exists to try to try to keep UHD and the FPGA(s) in lockstep when changes are made that both depend on.
In the case of B210 that number is defined in b200_core.v..search for COMPAT_MAJOR.
Likely you have just got your installed UHD and the FPGA version you are building from out of step. Rebase both from the same git commit and you should be fine.
