Hardfault error when writing to flash memory on Cortex-m3

done a bit more sleuthing.  Talk about convoluted!  I think I have managed to work out that the instruction is generating a ''precise data bus error''  Nowhere in all the manuals I have does it actually explain WHAT a ''precise'' error is.  Does anyone know what it means and how to fix it?

Cheers
