DMA Not Functioning

Hi,

I tried to program the DMA of the MCBSTR9 board but found out that it does not work. So far, Timer, ADC, VIC, & GPIO work for me.

The funny thing I see is that when I use simulation mode and run it in debugging mode, writing into the DMA registers like:

DMA->CCNF= 0xc000;

or

DMA_Channel3->SRC = &sourceAddress;

give "no write permission" warning message. The same thing goes for reading these registers.

I do not get this error for other on-chip peripherals I mentioned above. Can someone shed some light?
