Thanks, after reading the materials for initialization script. I think
the procedure for running a program when the board boot should be:
1) put the c program on the location like: /etc/a
2) Put a line at the top of /etc/init.d/rcS:
export TZ=`cat /etc/a`
I'm not sure what you are hoping to do with this.
3) Put the same line in /etc/profile
I don't think you mean /etc/profile. You might mean /etc/rc.local. All
you should need to do is to add a line calling your c program near the
end of the rc.local script, e.g.
/etc/a/c_program_to_read_dio
Then the program will run when the board power up? But my board fail
to run it, any mistakes?
thx
