altera_fpga_manager ff706000.fpgamgr:timeout

Hello,

I am currently working with an Altera DE1-SoC FPGA board on OpenCL with MSEL set to 01010.
So, I was trying out a project from github with link

https://github.com/Er1cZ/Deploying_CNN_on_FPGA_using_OpenCL ;

This project is about deploying CNN on FPGA using OpenCL on an Altera DE10-Nano. I tried out the steps provided in the project and I got stuck at the aocl command.

I run aocl program /dev/acl0 squeezenet.aocx

The result shown is
aocl program: Running reprogram from /home/root/opencl_arm32_rte/board/c5soc/arm32/bin
altera_fpga_manager ff706000.fpgamgr: timeout

I do not know why this happen, because i tried other OpenCL examples and it work perfectly.
My question is what is the usual root cause of this and how can I solve it? Could it be due to a difference in the board and if so, any other way than changing the board?

Any feedback/pointers to potential solutions are very welcome.

Thanks
