AM620-Q1: SK-AM62-LP Issue CSI-2 I2C Interfacing with OV2311 SCCB Protocol Always reads 0x00 from chip ID (0x300A)

gopal sharma

Part Number: AM620-Q1
Other Parts Discussed in Thread: SK-AM62-LP, SK-AM62A-LP

Tool/software:

Hi,

We are integrating the OV2311 image sensor camera( https://www.e-consystems.com/raspberry-pi-4/ov2311-mipi-2mp-monochrome-global-shutter-camera-module.asp ) module on CSI-2 interface and I²C in a Linux kernel driver. The sensor is detected at its expected i2c address. However, when attempting to read the Chip ID register (0x300A) or any register, we consistently receive 0x00.

We have verified the following:

The I²C bus is functional, and other devices respond correctly.
The sensor acknowledges its address.
Writing a register address followed by a read operation still returns 0x00.

The logic analyzer trace confirms the transactions are occurring.

Our reference driver is the TI OV2312 driver.

We need guidance on whether any hardware modifications are required to ensure proper communication between I²C and SCCB on the SK‑AM62‑LP — for example, removing or adjusting I²C pull‑ups.
Please suggest possible causes and recommended solutions.

Regards,
Gopal Sharma

Hello Gopal,

I asked a question at AM620-Q1: Adding CSI-2 Camera Support to SK-AM62-LP via J1 Connector , but didn't get a response. Can you please share how you connect your camera to SK-AM62-LP?

The OV5640 device tree overlay was originally written for this board: https://www.ti.com/tool/SK-AM62, which is different from the board you're using (SK-AM62-LP). You'll probably need some extra configuration to enable the MIPI connector SK-AM62-LP.

Regards,

Jianzhong

Hi jianzhong Xu,

We have confirmed the correct I²C address and established communication successfully. However, when reading the Chip ID register, it consistently returns 0x00.

We plan to work on the MIPI interface after completing the I²C control setup.

References for review:

Connection Image: camera_image_ov23.jpeg
DTS File: k3-am62x-sk-csi2-iil-ov2311.dtso
Driver File (I²C control only): ov2311.c

Please kindly advise on possible causes and potential solutions for the Chip ID read issue.

Regards,
Gopal Sharma

Can you provide more information and logs (such i2cdetect command)?

gopal sharma said:

Did you check the schematics of the board you're using and map it to the dts? If so, can you provide more details so that I can double check?

Thanks,

Hi Jianzhong,

We have cross-verified the pin mappings with the DTS, and everything appears to be correct according to me. The i2c clocks and data signals are visible on the oscilloscope on the same pins.

Please find attached the connection details of the camera and SK-AM62-LP, along with the logs.

Are you sure I2C bus 2 should be used instead of bus 4? Please double check the schematics of the board.

Hi Jianzhong,

Yes, this is expected. I²C2 is the master bus where the PCA9543 switch (0x71) is connected. The OV2311 camera is connected to channel 1 of the switch, which the kernel exposes as I²C bus 4.

So while the physical connection is via I²C2, the camera (0x42) appears on I²C4 due to the switch’s dynamic bus mapping. All interactions with the OV2311 should happen through I²C4.

Our observation is based on the logs below. Could you please verify if we're missing anything

Hi Gopal,

I double checked the schematic of SK-AM62-LP and believe your device tree is correct:

Let me loop in my colleague for some help.

Nick Saulnier , the image sensor can be seen at I2C bus 2 with address 0x42:

===== i2cdetect -y -r 2 =====
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- 54 -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- UU -- -- -- -- -- --

But I2C dump returns junk data:

===== i2cdump -y 2 42 =====

Can you provide some advice on how to debug the I2C?

Thanks,

Hello Jianzhong,

The i2cdetect output of UU tells us that a driver is currently using the device at address 0x42. Thus, i2cdump will fail to interact with the device at 0x42 (because Linux will not let i2cdump interfere with whatever the Linux driver is doing on 0x42).

Hello Gopal,

1) Where did you capture the waveform? Between the AM62x & the switch? Between the switch and the OV2311? Please verify that you see the same signals on both sides (e.g., make sure that the ACK signal is actually coming from the OV2311, not getting added in by the switch)

2) The waveform you captured showed a read command returning all zeros. Please share the waveform from before that read, showing a successful write interaction with OV2311.

The rise/fall timing for the ACK might be too close to the rising edge of the clock - hard to tell from looking at your waveform. But the AM62x seems to respond just fine in the waveform you shared, so let's ignore this for now.

3) I am having trouble finding a datasheet for the camera showing what kind of I2C frequency it is designed to interact with. Can you confirm this device was designed to work with 100kHz?

Regards,

Nick

Hi Nick and Jianzhong,

Thank you for your support.

Due to the lack of detailed information about the camera module hardware, we are facing some issues. After further hardware analysis, we realized there is another hardware layer between the image sensor and our driver. We are currently working on finding a method to interact with the image sensor and will get back to you soon.

Where did you capture the waveform?
Between the switch and the OV2311.
I am having trouble finding a datasheet for the camera showing what kind of I2C frequency it is designed to interact with.
The device is designed to work up to 400 kHz. We are trying it with a lower frequency.

Is it possible to debug a Linux driver using breakpoints? If so, please kindly share the method.
Currently, we are using Vim for driver development. If there is any preferred and more productive tool, please suggest.

Regards,
Gopal Sharma

Hi Team,

We have integrated the camera driver, and it is configured and loaded properly. However, we are facing a problem with streaming. Our camera supports the following formats:

if (code->index == 0)
    code->code = MEDIA_BUS_FMT_Y8_1X8;
else if (code->index == 1)
    code->code = MEDIA_BUS_FMT_Y10_1X10;
else
    code->code = MEDIA_BUS_FMT_Y16_1X16;

Is the j721e-csi2rx/j721e-csi2rx.c driver already capable of supporting this camera, or do we need to make modifications for proper support?

please advise if any additional changes are required in the kernel or module to support this camera?

Regards,
Gopal Sharma

Hi Team,

We tried the following command, but no frames were received. Although the stream started and continued until manually stopped, the out_grey.raw file remained 0 bytes.

Hello Gopal,

MEDIA_BUS_FMT_Y8_1X8 and MEDIA_BUS_FMT_Y10_1X10 are supported by the CSI-2 Rx driver.

gopal sharma said:
We tried the following command, but no frames were received. Although the stream started and continued until manually stopped, the out_grey.raw file remained 0 bytes.

How did you know the stream started? The v4l2-ctl command should show some progress like below:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 33.75 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 33.75 fps

Can you add "--verbose " to your command and see if it prints out any log?

Thanks,

Jianzhong

We also checked the waveform on the DSO and confirmed that data is present on the camera lane. However, we are not sure if the data is valid.

Hello,

Thanks for the detailed logs. Everything looks good on the SoC's CSI Rx side, the only thing that I can think of is either the sensor is not sending data properly, or the HW connection is having some issues. Can you check a few registers and see if the CSI Rx is receiving data, or if there are any errors?

Regards,

Jianzhong

Hi Jianzhong,

Thank you for support.

I think we need the live status of these registers during streaming.
Could you please share the method to read or print the live status of these registers from the kernel?

Regards,
Gopal Sharma

TI__Guru 59265 points

Hi Gopal,

You can use devmem2 command to read the registers. For example, to read error_irqs, you can do:

root@am62axx-evm:/opt/edgeai-gst-apps# devmem2 0x30101028
/dev/mem opened.
Memory mapped at address 0xffff95f0b000.
Read at address  0x30101028 (0xffff95f0b028): 0x00000000

Hi Jianzhong,

With the suggested method, we are still not able to fetch the register value.

We also tried using __iomem, but it caused the kernel to crash after inserting the module.

Please suggest an alternative method.

I would like to inform you that we observed data on the lane using a oscilloscope. In the normal case, it gets stuck after starting a stream on when i begin capturing frames. However, when we stop the data on the lane by making some code changes, the behavior changes — the driver starts and stops streaming randomly when I begin capturing frames.

This camera reference driver is based on the Raspberry Pi implementation. I have also attached the dmesg log from the Raspberry Pi, which may be helpful.

Hello Gopal,

I would recommend you to first debug whey devmem2 is not working:

The fact that this command doesn't work on your setup tells that your system may have some problems.

Hi Jianzhong,

These registers may be mapped by the driver, such as cadns-csi2rx, and attempting to read them at runtime shows an error. Other registers can be read successfully with devmem2.

#define CSI2RX_ERROR_IRQS_REG                   0x28
#define CSI2RX_ERROR_IRQS_MASK_REG              0x2C

static irqreturn_t csi2rx_irq_handler(int irq, void *dev_id)
{
        struct csi2rx_priv *csi2rx = dev_id;
        int i;
        u32 error_status;

        error_status = readl(csi2rx->base + CSI2RX_ERROR_IRQS_REG);

        for (i = 0; i < CSI2RX_NUM_EVENTS; i++)
                if (error_status & csi2rx_events[i].mask)
                        csi2rx->events[i]++;

        writel(error_status, csi2rx->base + CSI2RX_ERROR_IRQS_REG);

        return IRQ_HANDLED;
}

static const struct csi2rx_event csi2rx_events[] = {
        { CSI2RX_STREAM3_FIFO_OVERFLOW_IRQ, "Overflow of the Stream 3 FIFO detected" },
        { CSI2RX_STREAM2_FIFO_OVERFLOW_IRQ, "Overflow of the Stream 2 FIFO detected" },
        { CSI2RX_STREAM1_FIFO_OVERFLOW_IRQ, "Overflow of the Stream 1 FIFO detected" },
        { CSI2RX_STREAM0_FIFO_OVERFLOW_IRQ, "Overflow of the Stream 0 FIFO detected" },
        { CSI2RX_FRONT_TRUNC_HDR_IRQ, "A truncated header [short or long] has been received" },
        { CSI2RX_PROT_TRUNCATED_PACKET_IRQ, "A truncated long packet has been received" },
        { CSI2RX_FRONT_LP_NO_PAYLOAD_IRQ, "A truncated long packet has been received. No payload" },
        { CSI2RX_SP_INVALID_RCVD_IRQ, "A reserved or invalid short packet has been received" },
        { CSI2RX_DATA_ID_IRQ, "Data ID error in the header packet" },
        { CSI2RX_HEADER_CORRECTED_ECC_IRQ, "ECC error detected and corrected" },
        { CSI2RX_HEADER_ECC_IRQ, "Unrecoverable ECC error" },
        { CSI2RX_PAYLOAD_CRC_IRQ, "CRC error" },
};

Is it possible to read these registers at runtime using a debugger or CCS?

Gopal Sharma

Hi Gopal,

The registers are mapped, but devmem2 should be able map the physical address to the virtual address and read the value. Your successful command showed the mapping.

Hi Jianzhong,

Thank you for support.

However, we are still facing issues reading the CSI-2 register values.
Could you please suggest if there are alternative methods to resolve this or recommended approaches for debugging the CSI-2 streaming problem?

Gopal Sharma

If you're using SDK 11.0 or 11.1, you could try the log-status of v4l2-ctl command. Find the subdev number of the sensor in "media-ctl -p" command, and then run "v4l2-ctl --log-status -d /dev/v4l-subdevX". For example:

root@am68-sk:~# v4l2-ctl --log-status -d /dev/v4l-subdev1

Hi Jianzhong,

Thank you for support

I did not see any errors in the output of v4l2-ctl --log-status -d /dev/v4l-subdev2 both with and without streaming.

However, we did find some debug logs in cdns-csirx.

Detailed logs are as follows:

Could this possibly be the cause of the problem?

The log message "Optional interrupt not defined, proceeding without it" appears when the interrupt is missing. If the interrupt is defined in the DTB, the driver should instead print error messages related to stream errors. How can I enable the interrupt to see the CSI-RX error logs, even though the interrupt is already present in the DTB?

Also, please share the any camera driver or camera module name that has been tested on the SK-AM62-LP CSI2 interface.

Is it possible to use the official Raspberry Pi Camera V2 ( https://robu.in/product/raspberry-pi-camera-v2 ) with the SK-AM62-LP board using the same driver as for the SK-AM62A-LP, without any modifications?

We need this to easily test the setup using an already tested reference camera module.

Gopal Sharma
