Hi guys,


I'm trying to use DMA for one of the UART's on TWRK65F180M using MQX 4.1


I have already implemented the UART driver using interrupt and it works fine. Now I want to use DMA for that UART for obvious reasons.


I can see a file in the BSP project with the name serl_dma_kuart.c which contains function related to DMA. But I don't see those functions being referenced anywhere else.


Does MQX support DMA for UART's?


Your help is much appreciated. Thank you.
