Tim,

it looks like you're doing everything correctly. What's the filename of the
cal file (you can blank out the serial)?

Are you building from source? If so, can you please recompile with

cmake -DUHD_LOG_MIN_LEVEL=trace

and set the environment variables

UHD_LOG_LEVEL=trace
UHD_LOG_CONSOLE_LEVEL=trace

? This will tell you where it's trying to look for the cal file.
