Hi TI,
I configure wkup_gpio0_7 as the wakeup source from “mem” power state, but it always fail, could you please help? I'm using SDK8.0, thanks
dts:
gpio_keys: gpio-keys { compatible = "gpio-keys"; autorepeat; pinctrl-names = "default"; pinctrl-0 = <&sw11_button_pins_default>; sw11: sw11 { label = "GPIO Key USER2"; linux,code = <KEY_WAKEUP>; gpios = <&wkup_gpio0 7 GPIO_ACTIVE_LOW>; interrupt-parent = <&wkup_gpio0>; interrupts = <7 IRQ_TYPE_EDGE_BOTH>; debounce-interval = <10>; wakeup-source; }; }; &wkup_pmx0 { sw11_button_pins_default: sw11-button-pins-default { pinctrl-single,pins = < J721E_WKUP_IOPAD(0xcc, PIN_INPUT, 7) /* (G28) WKUP_GPIO0_7 */ >; }; };
fail log:

Hi,
Suspend to RAM is NOT supported in the SDK. So this will fail.

Hi Keerthy,
Could you please explain to me more details about why SDK not support this issue? Is it because SDK not make PMIC to response to the suspend action? thanks

Yes. There is no low power mode support for TDA4. No interactions with PMIC or even PMIC driver support is present. So this feature may be supported
in future but we do not have a definite date.
