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
