ioremap: How to

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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
void main()

Thanks and regards,
Rahul Patil
