imx6sll evk sdio wakeup

prasanth — Mon, 15 Feb 2021 08:42:49 GMT

Hi,

We are using imx6sll evk for the host, We are interfacing sdio based external wifi to the host. We are using WOW(wake on wireless) feature to wake up the host from suspend state. Here GPIO90 is using as sdio wakeup pin. we are using command "echo mem > /sys/power/state" for suspend mode. But we are not able to wakeup the host. Please help me to wake up the host.

Thanks,

Prasanth.
