Hi, all
I built an epics application, and I used two functions like this:
#include <devLib.h>
char *localaddrstart;
unsigned short int testvalue=INIT_TESTVALUE;
unsigned long baseaddr = 0x20200000;
if (devRegisterAddress("VME_mapping", atVMEA32, baseaddr, sizeof(struct
channel), (char *) &(localaddrstart))!=0)
{
printf("Out of Bus Mem Map!\n");
return -1;
}
if (devReadProbe(1, localaddrstart, &testvalue) < 0)
{
printf("No board at this address!\n");
return -1;
}
then, I past the compilation, but when I download the object file to the
target board, and there are the following errors:
ld("../bin/RTEMS-mvme5500/power_supply.obj")
Unresolved symbol: pdevLibVirtualOS
Unresolved symbol: pdevLibVirtualOS
Unresolved symbol: pdevLibVirtualOS
Unresolved symbol: pdevLibVirtualOS
Unresolved symbol: pdevLibVirtualOS
......
any help is appreciated, thanks a lot!
