Need information about programming embedded Linux devices in C

Hi all

I am confused .

When one tries to write code for an LINUX based embedded board.

That code is aimed to control some leds .

How that code is wrien in C and then compiled
and installed as a program in the board memory ?

Or does LINUX offer regular C like commands like

Please clarify it for me .

Typically embedded single board computers do not contain enough memory to hold all of the headers and libraries necessary to compile a program. So you would set up a development system on a regular PC that includes the aforementioned stuff plus a cross compiler as necessary. The cross compiler is c and all the regular syntax is the same.

Take for example an ARM based embedded board like the Pandaboard. When the embedded board already has a running linux system it might include a serial port that can be used as a console terminal. A terminal program such as minicom, cutecom, kermit etc is used to communicate with the SBC. You could upload your program via a terminal transfer program or maybe via a flash drive if capable.

Do I include LINUX header files at design time ?

The C programming language is largely the same regardless of the build or target host architecture. Target-specific code would be determined by the presence or lack of an OS or by addressing (literally and figuratively) the target hardware. A good deal of code targeting Linux generically will build and run equally well on any Linux OS host.
