Failed compiling GPIO-example of Starterware / unresolved symbol Entry


I'm just doing some first steps in bare-metal programming of BeagleBone Black.

I downloaded Starterware and CCS vom TI, got the correct .gel file,
imported the GPIO-Example (LED-blinking) from Starterware into CCS,
adjusted the project settings to work with newer ARM compiler version
5.1.1 and tried to compile the whole thing.

Now CCS gives me an error

unresolved symbol Entry

This "Entry" thingy can be found in gpioLEDBlink.cmd:

.text:Entry : load > 0x80000000

But: why doesn't it compile? What do I have to change to compile the
whole thing successfully?
