How configure a pin as Open Drain for i.MX7D using the config tool

HOTA — Fri, 25 Aug 2023 08:46:38 GMT

Hi,

How can I configure a pin as Open Drain for i.MX7D using the config tool?

I was unable to find the option to configure it.
Also, please tell me how to configure it as an interrupt PIN in the same way.

I use Ver 13.1.

Thanks,

HOTA

I hope you are doing well.

i.mx7D pins cannot be configured in Open Drain IO mode.

One can refer to the below-mentioned link for more details:

How should I configure the interrupt PIN?
I now understand about open-drain. Thank you!

One cannot configure interrupt for a pin from i.MX Config tool.

One has to make changes in the device tree. Please refer to imx7d-sdb.dts, specifically to the tsc2046 node.
