FPGA to HPS Bridge access

Hello everyone, I've been trying to send data from FPGA to HPS. I have a few soft IP cores in the FPGA and I want the HPS to read signal data from one of these cores (2 signals of 16 bit width...

Sorry for# 2, I thought you wrote F2H as a typo. F2H is for the FPGA to access the memory space of the HPS. For the HPS to access the memory space of the FPGA you have to access the H2F or lightweight H2F bridges (which need to be remapped like you said in the first post).

So the calculation for the physical address would be: h2f_base_address + peripheral_address.
