iMX93 ADC

BaselHn — Thu, 24 Jul 2025 11:26:23 GMT

Hi,

I want to enhance the iMX93 ADC driver to support DMA and an iio buffer, so it can sample several samples and put them into a buffer.

Attached is my modified code. And I get the following error:

[ 1.436577] imx93-adc 44530000.adc: error -EINVAL: Failed to register this iio device.
[ 1.444518] imx93-adc: probe of 44530000.adc failed with error -22

Any help?

Hello @BaselHn

I hope you are doing very well.

Have you tried changing the line:

indio_dev->modes = INDIO_DIRECT_MODE; //| INDIO_BUFFER_TRIGGERED;

To:

indio_dev->modes = INDIO_DIRECT_MODE | INDIO_BUFFER_TRIGGERED;

Best regards,

Salas.

Hi @Manuel_Salas

Sorry for the late response I was OOO.

Yes and I managed at last to make the ADC to work with the DMA.

The ADC now working with DMA.

Hey, did you ever get this working with continuous mode?
