The IMX219 sensor driver does not control the GPIO

[videodev]

Hi there!

with “manual” supply of a high level to the EN input of the video sensor module IMX219, the driver works fine and the sensor is available in the system, also the Argus-Camera connects without any problems and broadcasts the image from the sensor.

But at the same time, CAM0_RST_L TEGRA234_MAIN_GPIO(H, 3) is not controlled from the driver.

but in “manual” mode GPIO(H, 3) can be controlled.
log shows system registration and GPIO(H, 3) control.

hello videodev,

it doesn’t looks correct.
why you have two cameras that’s were sharing same GPIO pin.
for example,

	i2c@31e0000 {				
		imx219_cam0: rbpcv2_imx219_a@10 {
			pwdn-gpios = <&tegra_main_gpio CAM0_RST_L GPIO_ACTIVE_HIGH>;

	i2c@c240000 {					
		imx219_cam1: rbpcv2_imx219_g@10 {
			pwdn-gpios = <&tegra_main_gpio CAM0_RST_L GPIO_ACTIVE_HIGH>;

Hello JerryChang,

physically, the pin is connected to one camera connector and one camera is connected,
made changes.

Kernel dtb to dts.

still CAM0_RST_L TEGRA234_MAIN_GPIO(H, 3) is not controlled from the driver.

Thanks!

hello videodev,

may I know which JetPack release you’re working with?
I saw some issues while using GPIO marco, could you please try using GPIO number directly,
you may using $ sudo cat /sys/kernel/debug/gpio | grep PH.03 to check the GPIO number.

Hello JerryChang,

Jetpack 5.0.2 ,

nv_orin@nv:~$ sudo cat /sys/kernel/debug/gpio | grep PH.03
gpio-394 (PH.03               |camera-control-outpu) out lo 

log shows system registration and GPIO(H, 3) control.

@videodev

Jetpack 5.0.2 ,

hello videodev,

I did see some issues related to GPIO marco on JP-5.0.2,
you may either upgrade to later Jetpack release version, or trying below to control the pin, i.e. pwdn-gpios = <&tegra_main_gpio 394 GPIO_ACTIVE_HIGH>;
