Continuing the discussion from [IMX219] Four camera don't work on Nano custom board design:

Hello,

I want to return to the above topic. Now, I have four cameras, so I tested this setup and unfortunately, it didn’t work. Two cameras work fine and two cameras have errors during boot:

[    2.832691] imx219 32-0010: imx219_power_get: unable to request reset_gpio (-16)
[    2.840178] imx219 32-0010: unable to power get
[    2.844754] imx219 32-0010: tegra camera driver registration failed
[    2.851235] imx219 33-0010: imx219_power_get: unable to request reset_gpio (-16)
[    2.858717] imx219 33-0010: unable to power get
[    2.863293] imx219 33-0010: tegra camera driver registration failed

And in catalog /dev I see only 2 cameras, which work fine.
Hardware connections are below:
[PWDN] → [i2c mux address] → [CSI channel] → [port-index in dts] [status, when 4 cameras are connected)
CAM1_PWDN → i2c-30 → CSI_E → port-index = <4> (work fine)
CAM0_PWDN → i2c-31 → CSI_C → port-index = <2> (work fine)
CAM0_PWDN → i2c-32 → CSI_A → port-index = <0> (doesn’t work)
CAM1_PWDN → i2c-33 → CSI_F → port-index = <5> (doesn’t work)

I tested a few configurations of the connection two cameras:

  1. CSI_A and CSI_F, then cameras works
  2. CSI_A and CSI_E, then the camera connected to CSI_A works only. Camera connected to CSI_E plot log:
    [ 2.811106] imx219 30-0010: imx219_board_setup: error during i2c read probe (-121)
    [ 2.818838] imx219 30-0010: board setup failed
  3. CSI_A and CSI_C, then the camera connected to CSI_A works only. Camera connected to CSI_C plot log:
    [ 5.012817] imx219 31-0010: imx219_board_setup: error during i2c read probe (-110)
    [ 5.020725] imx219 31-0010: board setup failed
  4. CSI_C and CSI_F, then cameras works. What is interesting in the log from Connector for CSI_A is other than standard when the camera isn’t connected
    [ 2.852544] imx219 32-0010: imx219_power_get: unable to request reset_gpio (-16)
    [ 2.860025] imx219 32-0010: unable to power get
    [ 2.864600] imx219 32-0010: tegra camera driver registration failed
    The standard log when a camera isn’t connected is: imx219_board_setup: error during i2c read probe (-121).
  5. CSI_E and CSI_F, then the camera connected to CSI_F works only. Camera connected to CSI_E plot log:
    [ 2.815436] imx219 30-0010: imx219_board_setup: error during i2c read probe (-121)
    [ 2.823177] imx219 30-0010: board setup failed

The hardware looks correct because every camera work in some configuration of connection. Problems are when two cameras use one PWDN pin. I tested four separately PWDN pins but it didn’t help.
Can you check out my device tree?

Looks like HW problem cause I2C failed communication.

I use one pin PWDN for two cameras, Is it fine?

5

I don’t think using the same pin would be fine.

I added two gpio so every camera has its own pwdn. Device tree:

#include "tegra210-camera-rbpcv2-dual-imx219.dtsi"

#define CAM0_PWDN	TEGRA_GPIO(D, 3) //CAM_E
#define CAM1_PWDN	TEGRA_GPIO(G, 2) //CAM_C
#define CAM2_PWDN	TEGRA_GPIO(S, 7) //CAM_A
#define CAM3_PWDN	TEGRA_GPIO(T, 0) //CAM_F



#define CAMERA_I2C_MUX_BUS(x) (0x1E + x)

				};
			};
		};
	};
};

In pinmux settings are like below:

			uart3_rts_pd3 {
				nvidia,pins = "uart3_rts_pd3";
				nvidia,function = "uartc";
				nvidia,pull = <TEGRA_PIN_PULL_UP>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};
			uart2_rts_pg2 {
				nvidia,pins = "uart2_rts_pg2";
				nvidia,function = "rsvd2";
				nvidia,pull = <TEGRA_PIN_PULL_UP>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};
			cam1_pwdn_ps7 {
				nvidia,pins = "cam1_pwdn_ps7";
				nvidia,function = "rsvd1";
				nvidia,pull = <TEGRA_PIN_PULL_NONE>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

			cam2_pwdn_pt0 {
				nvidia,pins = "cam2_pwdn_pt0";
				nvidia,function = "rsvd1";
				nvidia,pull = <TEGRA_PIN_PULL_NONE>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

In this configuration, work only two cameras are connected to CSI_E and CSI_C. Others return errors:
imx219 32-0010: imx219_board_setup: error during i2c read probe (-121)
imx219 32-0010: board setup failed
imx219 33-0010: imx219_board_setup: error during i2c read probe (-121)
imx219 33-0010: board setup failed
Is it everything that I must change in the device tree for four pwdn pins?

You may need to probe those power down/Reset … PINs to confirm their state.

Hello,

I found that pwdn pins are shaped. After correcting this mistake, all cameras are present in /dev/video* catalog. But I can run 3 cameras only (the queue doesn’t influence for error. Always, the last camera doesn’t work).
When I change the resolution to 1920x1080, then all cameras work fine.
Which resolution is recommended as the highest for 4 cameras?

Below are logs:
