AM4378: ADC1 Linux driver support

Paul Reeves

Part Number: AM4378

Hi,

We are working on an AM4378-based product which uses ADC1. Is there official TI Linux driver support for ADC1? We were unable to find it in the current TI SDK 6.03.

Thank you

Hello Paul,

Looks like we need to add to the documentation. AM335x and AM437x use the same Linux ADC driver.

Regards,

Nick

Hi, Thank you. It looks like the referenced Linux ADC driver that you provided above only supports ADC0.

Can you confirm that it supports ADC1? It is our understanding that it does not.

Nick, just pinging this thread to see if you've been able to further research ADC1 support in SDK6.03.

Hello Paul,

Apologies for the delayed response. You are correct, AM437x ADC1 is not supported by the TI Linux driver as of SDK 6.3.

It looks like there is a patch to get ADC1 working on SDK 3.2, but post ADC1 support for am437x-gp-evm indicates that there were too many driver changes to get the patch working on SDK 4.0. So I am not sure how useful that old patch would be.

Regards,

Nick
