Programming the NBX in C

So you want to run your own code on the NBX 100? Its not that hard.

First make sure you have the right Development Tools

Here is my test.c

extern myOwnFunction() {
        int i;
        for(i=0;i<2;i++)        // do it 2 times...
                memShow();      // Just call something else for now
        return 0;
}

memShow() {
        asm ( "call *__memShow" );
}
int __memShow=0x00959570;       // only for 4.1.4a

Now goto the console:

nbx100-> cd "/htfs0/tmp"
nbx100-> ld 1,1,"a.out"
value = 52192268 = 0x31c640c = a.out_bss + 0x8
nbx100->lkup "myOwn"
myOwnFunction             0x031c63d0 text     (a.out)
value = 0 = 0x0
nbx100->myOwnFunction
