I am migrating a code from Linux to ghs Integrity Real Time OS. The code requires opening physical/main memory and then map the physical to virtual memory using mmap.

In Linux, main memory is accessed by,
fd = open(“/dev/mem”, O_RDONLY);
void * virt_addr = mmap(NULL, 0x20000, PROT_READ | PROT_WRITE, MAP_SHARED, physical_addr);

int32_t register_access = ((UINT8 *)virt_addr + 0x2000);

Note: physical_addr is a physical address of base address register(BAR) in PCI.

Can you please let me know how this can be accomplished in Integrity.

Thanks in advance
