简短一点就可以。THX
general 的.

如果有什么书比较好的也可以一并列出。

i think that book, 'let mips run', is a good book on mips. and arm cpu also have a similar book. i learnes embedded linux on arm cpu all from web. once i meet a problem, search from web. and read cpu reference from vendors. one register by one register, really painful. this week, i spend almost whole week on a small register overwriten problem. painful.

Thx, Dragonfly.
oh? Not too much guy care about embebed development here.  :-(

Dragonfly

people need a warm up period. and doing embdedded linux development, u need hardware support. not everybody have that. so a little painful.

dolephi9080

That's true. As u say the board is really expensive. It's hard to afford for a personal lover.

Dragonfly

yes, so it decides the population of embedded people. and people have different requirement on embedded systems. so it is impossible to buy boards in volume.

Hey, Dragonfly I still have a question. If I want to buy a board, what's point I need to consider?
surpose:

Do the os support that board and cpu?
What kind of port and module needed in the embeded device?
[/list:u]

These are surposes. I'm a newbie here. I'm curious how the thing control a electrical appliance for a long time. I want to understand it, so maybe I will purchase a second hand board for practice.  
like a fire alarm system.

Dragonfly

u need to know what functionality u want, a small nas may need a pci slot or ide controller, a netcam may only need a mac , usb.... u need to know what interface, expansion slot. u need.

then check web if linux support this kind of board, what is the extent it supports.
