How to run HRTIM DMA to GPIO?

[TSchi.3]

Hey Community,

i am working on a parallel output interface. I want to realize it with GPIOE and all of the 16 Pins.

To Generate an output i used TIM2 to trigger DMA1 so far so good. The Output is working with memory to peripheral. The DMA is copying the databytes from the SRAM into the GPIOE->ODR Register (fmax=24MHz). Now i want to use HRTIM to generate the DMA request for more precise and faster Output.

I could not get it to run. Here my Code:

ALIGN_32BYTES(__attribute__((section (".sram1_s0"))) uint32_t msg2[]) =
{
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),

		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
		((uint16_t)0x0100),((uint16_t)0x0000),
