BeMicro SDK - how to access SD card

I must be doing something wrong. I cannot seem to get the breakpoints to work. I see this in the Console:

Using cable "USB-Blaster [USB-1]", device 1, instance 0x00

Pausing target processor: OK

Reading System ID at address 0x080002A8:

ID value verified

Timestamp value was not verified: value was not specified

Listening on port 10249 for connection from GDB: 59saccepted <<< there 3 boxes between 59s and accepted

I pause the execution and see this in the stack:

Why can't I break at alt_main? Why don't the breakpoints work? There must be a switch I missed.
