New ContributorHow to directly access linux's RAM with FPGA on de10-nano
Hello, I am using the de10-nano dev board and I have modify the DE10_NANO_SoC_FB demonstrations, which is used for LXDE desktop I want to know how to access the ram address on linux system with FPGA...

Frequent ContributorHello,
I would like to know what do you want to do with your design?
Is it sending data from FPGA to HPS? or reading HPS SDRAM via FPGA?
Thank you
PChi0We want to storage an huge array (around 20Mbit) by HPS into SDRAM and read it with FPGA once HPS finish the assignment.
durning the FPGA operation there's around 10M bit data we have to temporally storage, and we want to storage it in SDRAM.
the c program will never operate the these memory when FPGA is operating
we are using the PIO to use specify address to serial input each data, now but we think the program could be accelerated when FPGA can read SDRAM directly.
Thank you for replying
