There have been multiple reports of the DMA failing to operate properly unless the target memory area lies in RAM2. The symptom is not visible during debugging but only when the controller is run standalone. So far NXP hasn't made a single attempt to explain why the DMA works reliably with RAM2 but not with the standard RAM area so the only conclusion left (for me) is that NXP is aware of a design bug doesn't want to admit.
