Change pins Drive strength runtime

nirmalluhana — Wed, 18 Sep 2019 08:50:13 GMT

Hello,

Release: Yocto-Sumo (4.14.78_1.0.0_GA)

Board: i.MX8MQ based custom board

I want to change pins drive strength runtime without board reboot.

Is it possible to do it? If yes, then what utility or steps I have to follow?

Best regards,

Nirmal

Hi Nirmal

I am afraid it is not supported in nxp linux bsps, one can try to write to iomux

registers directly from application.

Hi Nirmal

there is no special application for it. One can use for example

memtool for adding codes to custom application :

memtool\test - imx-test - i.MX Driver Test Application Software
