Hello,

Thanks again for the reply.

I manage to compile and run successfully on the fpga. I compiled the matrix multiplication kernel and took 2 hours and 25 minutes for completion.

However, the problem was very odd. It was due to the network connection

SOLUTION:

I disconnect the machine from the network ( I took out the Ethernet cable ) and it worked in the first go.

Previously, I used only ssh connection to the machine (only through Tmux e.g byobu, screen etc).

Is anyone experienced something similar before???

Also, I discover that some of the pre-complied examples given by nallatech for my current board or not compilied for the current BSP that they claim.

As many of them failed to run with a CL_INVALID_BINARY, while the rest working out of the box.
