2.8v power on AGX camera connector

I am using LI-JXAV-MIPI-ADPT 4CAM with AGX XAVIER, but I get no power 2.8 at pin 5 on the 20525 connector (on all 4 connectors). I wonder if there is a switch in the AGX XAVIER which enables the 2.8v power or there is something wrong with the camera interposer / Jetson. How can I debug?

No 2.8V output on Xavier. You should check with vendor of camera board for that.

How about pins 81 82 83 on the camera connector (J509)? It says 2.8V Camera Power Supply in the datasheet.

Yes, those pins are the 2.8V to camera connector. But isn’t your question about the 2.8V on camera board? The 2.8V on Xavier is controlled by GPIO36 as you can see in the P2822 schematic in DLC.

Thanks @Trumany .

I am adding the link for completeness and future reference
NVIDIA Jetson AGX Xavier Developer Kit Carrier Board Specification

I get no output on:
sudo cat /sys/kernel/debug/tegra_pinctrl_reg | grep gpio36
so I suppose GPIO36 is not enabled.

Could you advise how I can enable it?

Also, I fail to find the document where the TEGRA194_MAIN_GPIO was defined (or was it a header file?) Could you remind me where to find that information please?

Thanks!

Hello,

Please check the Xavier adaptation guide to change the pinmux spreadsheet and enable this pin as gpio.

There is something I don’t quite understand. In the device tree I have (GPIO36 is TEGRA194_MAIN_GPIO(N, 0) ) :

gpio@2200000 {
	camera-control-output-low {
		gpio-hog;
		output-low;
		gpios = <CAM0_RST_L 0 CAM0_PWDN_L 0 TEGRA194_MAIN_GPIO(N, 0) GPIO_ACTIVE_HIGH>;
		label = "cam0-rst", "cam0-pwdn", "cam0-pw";
	};
};

Then in /sys/kernel/debug/gpio I can see avdd-cam-2v8 is set to lo :

gpiochip0: GPIOs 288-511, parent: platform/2200000.gpio, tegra-gpio:

gpio-392 ( |avdd-cam-2v8 ) out lo

as well as here
$ dmesg | grep GPIO
[ 0.828390] GPIO line 490 (pcie-reg-enable) hogged as output/high
[ 0.828426] GPIO line 289 (pcie-reg-enable) hogged as output/high
[ 0.828483] GPIO line 339 (wifi-enable) hogged as output/high

[ 0.828605] GPIO line 392 (camera-control-output-low) hogged as output/low

However at some point later, it is disabled:
$ dmesg | grep avdd-cam-2v8
[ 0.848106] avdd-cam-2v8: 2800 mV
[ 5.825028] avdd-cam-2v8: disabling

Is there a way that I can figure out which snippet is disabling the avdd-cam-2v8?

HI,

I think there are 2 places in your dtb using the same GPIO pin. To make it more easier to understand, you didn’t define a name “avdd-cam-2v8” in gpio@2200000 controller…
Thus, there must be a regulator with this name. Please disable it and only keep the one under gpio controller.

Okay, can you advise how to do it properly?

I have vana-supply = <&p2822_avdd_cam_2v8>;

in my device tree. I get 1v2 1v8 3v3 on my camera board, but no 2v8. What am I missing?

/ {

gpio@2200000 {
	camera-control-output-low {
		gpio-hog;
		output-low;
		gpios = <CAM0_RST_L 0 CAM0_PWDN_L 0>;
		label = "cam0-rst", "cam0-pwdn";
	};
};

i2c@3180000 {
	tca9546@70 {
		compatible = "nxp,pca9546";
		reg = <0x70>;
		#address-cells = <1>;
		#size-cells = <0>;
		skip_mux_detect = "yes";
		vcc-supply = <&p2822_vdd_1v8_cvb>;
		vcc_lp = "vcc";
		force_bus_start = <CAMERA_I2C_MUX_BUS(0)>;

		i2c@0 {
			reg = <0>;
			i2c-mux,deselect-on-exit;
			#address-cells = <1>;
			#size-cells = <0>;
			imx334_a@34 {
				clocks = <&bpmp_clks TEGRA194_CLK_EXTPERIPH1>,
						 <&bpmp_clks TEGRA194_CLK_EXTPERIPH1>;
				clock-names = "extperiph1", "pllp_grtba";
				mclk = "extperiph1";
				reset-gpios = <&tegra_main_gpio CAM0_RST_L GPIO_ACTIVE_HIGH>;
				vana-supply = <&p2822_avdd_cam_2v8>;
				vif-supply = <&p2822_vdd_1v8_cvb>;
			};
		};
	};
};

};

Do I need to add avdd-reg = “vana”; to register in the regulator consumer list? I am not really sure I understand the details of < xxx >-supply and < xxx >-reg. Can you please clarify?

You may need to understand what is regulator. A regulator may contain a GPIO. Take your case as example, avdd-cam-2v8 may contain TEGRA194_MAIN_GPIO(N, 0).

A regulator could be deliver to other driver to control. For example, “vana-supply”, “vif-supply” take regulators as input.
After it is delivered to a driver, it will be controlled by that software driver. If that driver is not in use, you may see that regulator is being “disabled” as the log shows.

This would cause an extra problem that, if you already assign a regulator/gpio to a specific driver, then you should not put and hog it in gpio controller anymore. For example, if you assign a gpio to usb controller, the usb driver may need to toggle it through the regulator framework. However, you force that gpio to be either low or high in the gpio controller too. This would cause contradiction. Of course, the system would only pick one side to prevent such error. Thus, the setting in gpio controller may not take effect.

As for the file to define regulators, you could open your directory that includes all the dtsi files. Use grep to find all files which have avdd-cam-2v8. You shall find a file which defines this regulator. The file name should be something including “power-tree”.

Hi @WayneWWW

I compiled a new version of my IMX334 driver which is very similar to the IMX* drivers in

/kernel/nvidia/drivers/media/i2c/

However, I get pretty much the same behavior as before. It gets detected on boot, it gets bound:

Still, I get

[ 47.561518] tegra-i2c 3180000.i2c: no acknowledge from address 0x1a

(I also tried 0x34 which is supposed to be writing address, but same behavior) and I suspect the lack of power might be the reason for the above issue. Can you please advise what I am missing? Thanks a lot!

hello nouuata,

please check your sensor specification for the hardware specific settings.
usually, there’re regulators, 2v8, 1v8, and 1v2 used for power on sensor modules.
for example, you may look into device tree for “avdd-cam-2v8” regulator,

                p2822_avdd_cam_2v8: regulator@107 {
                        compatible = "regulator-fixed";
                        reg = <107>;
                        regulator-name = "avdd-cam-2v8";
                        regulator-min-microvolt = <2800000>;
                        regulator-max-microvolt = <2800000>;
                        gpio = <&tegra_main_gpio TEGRA194_MAIN_GPIO(N, 0) 0>;
                        enable-active-high;
                };

please specify correct regulator settings to resolve i2c no acknowledge failures.
thanks

Hi @JerryChang

Thanks for helping out!

I sorted out the power and I get 2v8 on the board now. I get no errors until the moment I try to write to the gain reg:

[    2.383102] imx334: board_setup pw on err: 0

I tried a few i2c addresses, but with no success. Does the i2c device address correspond to the address on the MCU in use?

Thank you!

hello nouuata,

please review the schematic,
which device using i2c address at 30-001b; do your write gain function working with MCU process together?
thanks

Hi @JerryChang

Sorry, it was a stupid question. There is an MCU STM32F030x8 on the camera board and I noticed it has a corresponding I2C register 0x4000 5800 - 0x4000 5BFF.

How can I obtain the i2c communication address?

hello nouuata,

it usually a regulator issue to cause i2c no acknowledge failures.
please review your kernel driver to provide correct regulator settings to your MCU device.
thanks

Hi @JerryChang

Can you please clarify a few more items?

  • According to the IMX334 datasheet I need to provide avdd1 and avdd2, as well as dvdd1 and dvdd2, and iovdd. I couldn’t find any other sensor having such requirements, so I am a bit puzzled here. Do I need to add two extra regulators like p2822_avdd_cam_2v8_extra in tegra194-fixed-regulator-p2822-1000.dtsi? I guess this is not the case otherwise camera_common_power_rail won’t be enough to hold 5 regulators, so it will need modification
struct camera_common_power_rail {
	struct regulator *dvdd;
	struct regulator *avdd;
	struct regulator *iovdd;
	struct regulator *vcmvdd;
	struct clk *mclk;
	unsigned int pwdn_gpio;
	unsigned int reset_gpio;
	unsigned int af_gpio;
	bool state;
};

So how do the five regulators get passed to the sensor?

  • Can you explain the usage of af_gpio and how it gets set? I couldn’t find a place in the public code where the cam_af_gpio is set.

  • I found just one 1v2 regulator p2822_vdd_sys_en in

tegra194-fixed-regulator-p2822-1000.dtsi

but I guess it is reserved for system use. Shall I add a new regulator to tegra194-fixed-regulator-p2822-1000.dtsi and get it used as

vdig-supply = <&p2822_vdd_1v2_new_cam_regulator>;

or can I reuse it?

vdig-supply = <&p2822_vdd_sys_en>;
