How to enable DMA Capabilities for CAN Driver for IMX8MPlus EVK - based on Linux

radhak4x — Tue, 26 Nov 2024 13:55:20 GMT

How can I enable DMA capabilities for the CAN driver on the IMX8MPlus EVK board (Cortex-A53) running Linux? Could you please provide suggestions?

I am based on i.MX8QMPlus(i.MX8MPlus)- Target - EVK - based on Linux with CAN driver Enabled ( I am compiling the same with yocto build environment).

Now, i have to enable the DMA capabilities for CAN driver.

Could you please provide suggestions from where to start and what modifications are needed?

Thanks

Hello,

There is no DMA CAN for cortex M4. you can find the Flexcan code driver explanation in the Linux Reference manual.
