I have a system design that FPGA will generate data, and update to DDR3 of HPS. then notify (interrupts ) HPS. and HPS start to transmit data into PC via Ethernet.
I have few questions of software design in this architecture, please help me to find the solution.
- How to reserve DDR3 memory region in Linux OS ? (Linux OS will not use this segment of memory).
- How to access reserved DDR3 memory region in Linux Application or Linux kernel ?
Thanks in advance.
