[Rock 4 C Plus Power Button]

Hello,

 

I tried to use the power button on my Rock 4 C+ running Armbian 23.02.2 Bullseye with Linux 5.15.93-rockchip64. It is able to power off. But I can't boot up the controller.

When I use the debian based radxa image the button works like expected.

 

I found this at the rk3399-rock-4c-plus.dts of the radxa kernel.

 

&rockchip_suspend {
	status = "okay";
	rockchip,sleep-debug-en = <1>;
	rockchip,sleep-mode-config = <
		(0
		| RKPM_SLP_ARMPD
		| RKPM_SLP_PERILPPD
		| RKPM_SLP_DDR_RET
		| RKPM_SLP_PLLPD
		| RKPM_SLP_CENTER_PD
		)
	>;
	rockchip,wakeup-config = <
		(0
		| RKPM_GPIO_WKUP_EN
		| RKPM_PWM_WKUP_EN
		| RKPM_USB_WKUP_EN
		| RKPM_USB_LINESTATE_WKUP_EN
		)
	>;
	rockchip,pwm-regulator-config = <
		(0
		| PWM2_REGULATOR_EN
		)
	>;
	rockchip,power-ctrl =
		<&gpio1 17 GPIO_ACTIVE_HIGH>,
		<&gpio1 14 GPIO_ACTIVE_HIGH>,
		<&gpio0 3 GPIO_ACTIVE_HIGH>;
};

 

I would test the overlay with current armbian build, but I doesn't  know where to place it. Maybe someone can help me here?

Hi @Austin Dubes,

did you find any solution?

Thanks

[Radxa rock 4 can bus]

Hi,

I want to use a mcp2515 can controller over spi1 or 2.

 

I read about internal flash is blocking the spi1.
 

Can I use another Chipselect pin to use the spi1 with GPIO?

 

Can you please give some advice where to start my research about overlays?

 

What else do I need to activate? (core moduls, driver…)
