It seems LPC845 DMA cannot write GPIO at 0xA0000000
I get DMA0 ->ERRINT=1 when trying to do the GPIO write.
As troublehooting step, I changed the dest address to RAM and do not get the ERRINTflag.
I have not been able to find a definitive source to say if this is truly impossible.
I did find a reference which is not definitive but hints that this might be the case:

Can someone please confirm?
