MK24FN1M UART1 7Mbit/s with DMA

Hi All,
I'm trying to configure UART via DMA in MCUxpresso using SDK on MK24FN1M0VLQ12. I need a UART run 7Mbit/s without interruption with minimal core load.
I want UART in FreeRun mode with circular buffer 8192Bytes. Received data without any intervention by the service SW. I do not know in advance the length of the frame RX.
The SW will only look at the position pointer to write the DMA to the ring buffer. I tried to edit project MK24FN1M0xxx12 .zip\boards\twrk64f120m\driver_examples\uart\edma_transfer\.   Without success :-(  . Can I find a project example with this configuration somewhere? With SDK, without SDK or with PEx?
