Reset the fpga from Linux using /dev/mem/

Hello,

I'm building a project in Quartus II for my board DE1_SoC.

I created an IP and then connected it with HPS using Qsys via AXI4-lite interface, then, I launched Linux Yocto in HPS to program the FPGA.

I used dd or cat to the port /dev/fpga0 when programming the FPGA with my project.

Do I have to reset the FPGA part after programming using my method above?

In similar platform from Xilinx, I am able to reset the FPGA by sending a value to Register Reset.

Can I do that in Altera? For example by sending a certain value with /dev/mem in a program.

Anybody with similar experience is welcome to give his/her opinion.

Thanks a lot!
