    Hi Vladislav,

    Can you please check the EDMA3 API: ~/ti/edma3_lld_2_12_05_30C/packages/ti/sdo/edma3/drv/edma3_drv.h? There are apis that disable dma transfer:
    EDMA3_DRV_disableTransfer() -> Disable DMA transfer on the specified channel
    EDMA3_DRV_disableLogicalChannel() -> Disable the event driven DMA channel or QDMA channel

    Also check the resource management layer APIs: ~/ti/edma3_lld_2_12_05_30C/packages/ti/sdo/edma3/rm/edma3_rm.h.

    Best Regards,
    Yordan
