Dear list,
I get a strange error when trying to compile a GRC model:

RuntimeError: RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected protocol compatibility number [7 to 9], but got 10:
The firmware build is not compatible with the host code build.
The weird thing is that it was working perfectly, before I updated it.
Any suggestion on how to fix this? (except the obvious regression to the
previous images).
Thanks.
Vlad.
This indicates that your USRP-N2XX firmware is at level 10, while the
host side is expecting something else. Update your *host side*
UHD code to match the firmware side.
