Failed to initialize user clock?

Hi @davidwigley,

Thank you for posting in Intel community forum and hope all is well.
I have tried the instruction in the similar nodes mention and are able to program successfully. (i.e. complete steps 3.6)

Hence suspecting there might be some missing steps, would suggest to to check on the following:
1) Selecting the correct development stack source which is 1.2.1.
2) Recompile the program by running make clean followed by make command.
3) Are you able to compile the opencl code into the FPGA executable successfully?
Please do try and let us know if that helps.

Best Wishes
BB
