accessing reserved ram for storing files.
On an embedded system, I have a predefined RAM space that is outside of the kernel memory. I want to access this area almost like a ramdisk, so that I can store some files. I don't mind writing my own kmod. But I was wondering if there is a better solution.
The preferred way is to access the space as a ramdisk, install a file system, and mount it as a part of the file system. But I don't know of way tools to create a ramdisk at a specific address and fixed size on a memory outside the kernel space.
Any thoughts or suggestions?
