Complier Error, Quartus Prime Fitter was unsuccessful

I am using Speed-clouds hardware acceleration platform with arria10. According to the manual, I have to replace a10gx\hardware folder with another folder that Speed-Clouds provided, or the .aocx do not fit my board.

But the errors occured again:

1. Sometimes the diagnosis passed, and sometimes failed with the mismatch of writing and readback.

2. I try to ignore diagnosis and program with host code, There is still a mmd error: can't load the windriver library. and the procedure still executed with the error. Sometimes it fails to create program with binary, it shows "error: cl_invalid_binary". But sometimes the board works well with the mmd error.

The result of diagnosis and jobs is random, reboot seems do not solve any problems.

I am wondering if there are some hardware fault occured?

Thanks for ur help !

DSP or BSP? It seems you are using Altera's Arria 10 devkit; the BSP for that board is updated with every version of Quartus and is included in the package itself. There should be no need to use an older version of Quartus/AOC.
