Hi,
I would like to write driver for SSD drive, but I don't know how to start. I want to write my own driver for ARM11, I know C and Asembler.

I was searching google with phrases like:
"how to write ssd driver"
etc... etc... but I haven't find any good explanation for it.

Please some information how to start with it. I know it's dumb topic, but I don't know where else to find help. Thank you!

The processor is not the important thing. It is the SATA controller that the SSD is connected to that you need to understand. That probably depends upon which particular hardware platform you are programming for. Try Googling with that in mind.

You need to know which board/SoC you're targeting (ARM11 is an architecture family), and then you need to grab its reference manual.

The reference manual will let you know what the controller is and will either define the interface, or allow you to then find a specification that you can use to program the controller the SSD is connected to.

Also note that it is possible to attach SSD drive over USB.
You may need to narrow down the first supported setup, so to narrow down the complexity.

What kind of an answer do you expect to such a question? Hey, while you're at it, tell me how to write a novel and how to draw photorealistic landscapes. Do you understand what the problem is? I suspect you were looking for someone else's code to call your own, distributed in "tutorial" form. What did I win?
