hi,
I want build an application that requires the exact memory address
(for LCD display). I use ioremap to achieve that. However, when i
try to compile the file, i get the following error.
implicit declaration of ioremap
and hence
unreferenced ioremap
I assume that this is becuase I can use ioremap only in kernel
mode. I have tried using ioperm and iopl, but these work only on
intel architecure and my platform does not support this. Nor do i
have the device file /dev/port for my platform.
Is there are any way, I can access and set the memory directly in
the user(application) mode ? I do want to avoid building a driver
and recompiling with the kernel.
The source code is as simple as
#include<asm/io.h>
void main()
{
ioremap(0x10000,100);
}
Thanks and regards,
Rahul Patil
