I am using CAN gateway functionality and the microcontrolller I am using is XMC4402.
My Source message object is CAN message object 1(on CAN node 1). Desination message obejct is CAN message object 0(on CAN node 0). The CANgateway is working fine.
I have also configured DMA channel 4 to copy data from CAN message object 0(destination message object) to a software buffer. The DMA part of implementation is not working. Also there are other DMAs configured in my application for other functionalities. Is there any care that has to be taken while configuring DMA Request Line?
I have configured DMA Line = 2 and RS2(DLR_SRSEL) = 10 which is not used by any other DMA channel.
