Hi everyone, I am very new to Embedded Linux. I know that the MMU handles all of the address translations from Virtual to Physical. My question is that how does the MMU know which physical addresses actually have RAM? Is this information provided by the CPU? Kernel? Bootloader? For example, if I have a board with the first bank of 64MB DRAM mapped to 0xa0000000 and second bank of 64MB DRA...

I'm designing a device that can display high resolution (at least 1080i or 1280x1024) images to a LCD monitor. I don't think that much 2D/3D acceleration is needed for this purpose. Lower hardware cost is the first priority, although ease of development is important too. What is the best route? 1. Microprocessor only, to run embedded Linux and software-based display controller 2. Micr...
