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
