Hi All,

We want to use eDMA for ethernet in our project in IMIXRT1170. Is there any driver for ethernet eDMA for this Processor. If no, then how to use eDMA for ethernet.

We saw eDMA driver for various peripherals like LPUART, FlexIO etc. but this is not available for ethernet. Is there any specific reason behind that.

Tools Used:

IDE: MCUxpresso v11.4.1

SDK 2.10.1

Hello,

   i.MX RT1170 ENET has own unified DMA (uDMA), internal to the ENET module, which
optimizes data transfer between the ENET core and the SoC, and supports an enhanced
buffer descriptor programming model to support IEEE 1588 functionality.

  There is no need for eDMA.

Regards,
Yuri.
