I tried to toggle a pin with the a DMA triggered by a timer. With DMA0 it works properly but if I try to do the same with DMA1 it doesn’t work. DMA0 and 1 have the equal settings. I work with the A5 processor of TWR-VF65GS10 development tower debugged by DS-5 tool. I used the Processor Expert tool to generate the DMA init code.
