Assert reset signal in HPS

Hi,

I am using an Arria 10 with the HPS running Linux. I want to be able to reset devices such as i2c-0 and uart from software. I tried read/write to the reset manager register, but I receive an unhandled fault error and Bus Error. Is it possible to access the reset register from user-land? I am using mmap() to access the registers.

Thank you

    Do you reveal the IPs you want to reset at the FPGA side? What I understood that you want to reset devices IPs in FPGA from the LINUX, correct?
