I’d like to use a physical memory sapce in my software during its running time without any other program can also use this memory sapce.This means I need a safe and sapce large enough memory and I konw its starting address.
Please see if contiguous memory allocator of linux is what you’re looking for.
I mean this physical memory can be used directly.
unsigned int MEMBASE = 0xf5000000;
After above defination,I will give this address directly to FPGA configure register.
So,do you mean CAM can offer me this?
Please see if below topics help.
I have browsed all the links you give me.But I didn’t get a helpful answer.
I’d like to know a physical memory starting address then I will give the address to FPGA.So this memory must big enough and during my program executing other program can not use this memory.
