Usage of DMA in IMX7 on cortex m4

Hello,

We are using imx7 in a project. I am developing the Cortex m4 software. I want to use DMA with UART, I2S and SPI peripheral’s in the project. Is there a document or example that explains how to use DMA on the Cortex m4 side? I searched on the forum page but couldn’t find it.

Thanks in advance for your answers

Hello @Eray 

I hope you are doing very well.

Unfortunately NXP does not provide DMA drivers for RTOS on Cortex M on i.MX7D (Just to i.MX7ULP of i.MX7 Family as you can see on MCUXpresso SDK page). You can contact our professional services to get help with it.

Also, this community thread can be helpful: https://community.nxp.com/t5/i-MX-Processors/DMA-Support-in-FreeRTOS-package-for-imx-7s/td-p/613690

Best regards,

Salas.
