What type of Flash is it? Nor or Nand?

Since Flash is a Non Volatile memory, you cannot perform any test specific for the address lines of the Flash.
You will need to check on the Flash datasheet.  There is a command sequence to be followed to get the Manufacturer Id and Device Id of the flash. You can do this using a JTAG tool.
If you get the correct MAN Id and Dev Id, you can be sure that the Flash address lines and Datalines are fine.
