But still no change. Same green and purple output. 

Also the gstreamer feed is very slow i.e., when i wave my hand in front of the camera the feed takes  a long time to update the patterns.

Please resolve the issue soon.

They must be under the ov5640 -> port node and the vin3a node. 

Yeah ok. Earlier it was missing under vin3a node.

Hi Vishal,

Please add the vsync and hsync back.

Can you add prints to the I2C commands to see if there are any differences between the two releases?

Best,
Jared

Hi Jared McArthur ,

Jared McArthur said:

Please add the vsync and hsync back.

You mean set them back to 1 under both port and vin3a nodes?

Jared McArthur said:

By two releases you mean one where hsync and vsync are 1 and the other where hsync and vsync are 0? Which i2c commands are you referring to ?

Can you please be very specific when you post here ?

- Vishal 

Hi Vishal,

Vishal Maheshwari said:

Yes, I mean to set them both back to 1. It sounds like they were performing better with those settings based off of your comment.

Vishal Maheshwari said:

I meant 6.03 and 9.03. I would like to see what differences in the ov5640 I2C registers there are between the two. If the 9.03 release is setting more/less registers than 6.03, it could explain the difference in behavior.

You should be able to add a dev_info to the ov5640_write_reg function to see what is set.

Best,
Jared

Jared, 
I am on leave as I am ill.

I will tell the result soon!

Hi Vishal,

Thank you, please update the thread when you are able to.

Best,
Jared

Jared, 

I have set the values of hsync and vsync back to 1.

Do you want me to add back ti,vip-channels property ?

I will put the prints inside ov5640_write_reg function.

Basically, I will be printing out the values of reg variable in the driver and attach the  dmesg output here.

I will put the prints inside ov5640_write_reg function.

Basically, I will be printing out the values of reg variable in the driver as below.

printk(KERN_INFO "VM ********** reg value = %hu **************\n", val);

Here is the reg value output for 9.03 SDK's boot log.

Similary I put a print in the ov5640_write_reg function of 6.03's SDK ov5640 driver and I got nothing in the dmesg logs.

But I don't think these are useful to you. Please tell how do you want to modify the printk statement.

-Vishal

Hi Vishal,

I'd like to see which register and value are being written.

So something like:

printk("i2c reg: 0x%x, value: 0x%x", i2c_reg, i2c_val);

Best,
Jared

Jared, 

I put the printk in 9.03 SDK like you asked for.

printk("i2c reg: 0x%x, value: 0x%x", reg, val);

Here is the dmesg output below.

Hope the issue will be caught red-handed and rectified now !

Hi Vishal,

Can you send the 6.03 messages as well? I'd like to compare the two.

Best,
Jared

Jared,

I told you 6.03 SDK didn't give me any prints upon boot when I put the printk in ov5640_write_reg function.

-Vishal

Hi Vishal,

I need to be able to see the I2C values sent on 6.03 to compare. Does dev_info or placing the prints in another I2C reg function work?

Best,
Jared

Jared,

You tell me please!

There are so many functions where I can put the prints. Tell me the function name. I will revert then!

-Vishal

Hi Vishal,

Can you send the changes you added?

Does the following patch work?

I already told you I added a printk function in both 9.03 and 6.03 SDK in my previous replies.

Jared McArthur said:

I will send you output of this in 9.03 SDK as in 6.03 SDK the function doesn’t get called on boot. Although I am not sure it will get compiled. 
 
Will update you soon!

I already told you I added a printk function in both 9.03 and 6.03 SDK in my previous replies.

I just would like to see the code itself.

Vishal Maheshwari said:

I will send you output of this in 9.03 SDK as in 6.03 SDK the function doesn’t get called on boot. Although I am not sure it will get compiled. 

What does this mean? Is the probe function not called for the ov5640 on boot? Is it not compiled as a module?

Best,
Jared

Jared,

Currently this is the code for ov5640_write_reg function in both 9.03 and 6.03 SDK's camera driver.

static int ov5640_write_reg(struct ov5640_dev *sensor, u16 reg, u8 val)
{
        printk("i2c reg: 0x%x, value: 0x%x", reg, val);
        struct i2c_client *client = sensor->i2c_client;
        struct i2c_msg msg;
        u8 buf[3];
        int ret;

        buf[0] = reg >> 8;
        buf[1] = reg & 0xff;
        buf[2] = val;

        msg.addr = client->addr;
        msg.flags = client->flags;
        msg.buf = buf;
        msg.len = sizeof(buf);

        ret = i2c_transfer(client->adapter, &msg, 1);
        if (ret < 0) {
                dev_err(&client->dev, "%s: error: reg=%x, val=%x\n",
                        __func__, reg, val);
                return ret;
        }

        return 0;
}

Sorry, I thought there was an undefined variable in your patch, which is why I said the code wouldn’t compile. Of course, the probe function gets called. Ignore what I said earlier. 

Here is the updated code after your patch for both the SDKs.

I haven't added back the "ti,vip-channels = <1>;" line in DTS.

I have also commented the printk that I had added.

static int ov5640_write_reg(struct ov5640_dev *sensor, u16 reg, u8 val)
{
        //printk("i2c reg: 0x%x, value: 0x%x", reg, val);
        struct i2c_client *client = sensor->i2c_client;
        struct i2c_msg msg;
        u8 buf[3];
        int ret;

        buf[0] = reg >> 8;
        buf[1] = reg & 0xff;
        buf[2] = val;

        msg.addr = client->addr;
        msg.flags = client->flags;
        msg.buf = buf;
        msg.len = sizeof(buf);

        ret = i2c_transfer(client->adapter, &msg, 1);
        if (ret < 0) {
                dev_err(&client->dev, "%s: error: reg=%x, val=%x\n",
                        __func__, reg, val);
                return ret;
        }

        dev_info(&client->dev, "i2c reg: 0x%x, value: 0x%x\n", reg, val);

        return 0;
}

While for 6.03 SDK the camera driver's function ov5640_write_reg didn't get called on boot so no dmesg logs.

May be some other function is getting called at boot. I can attach the source code for ov5640.c for both the SDKs. 

6.03 's ov5640.c source code has been modified as per our requirements,

Hi Vishal,

I've looked over the 6.03 driver (ti-linux-4.19.y). The only 3 places an i2c_transfer happen are in ov5640_init_slave_id, ov5640_write_reg, and ov5640_read_reg. ov5640_write_reg has to be called within the initialization of the camera.

Are you reinstalling the driver after rebuilding it on the 6.03 image?

Best,
Jared

Are you reinstalling the driver after rebuilding it on the 6.03 image?

Yes, I copied the newly compiled ov5640.ko to my board using scp and rebooted. When I open the camera feed, the ov5640_write_reg function does get called — I can confirm this from the debug prints.

However, it doesn’t seem to be called during boot.

That’s why I asked if you needed the source code of our modified camera driver from the 6.03 SDK. It’s possible that its initialization flow got affected after our changes.

Hi Vishal,

Please send your modified camera driver.

If it isn't called during boot, this means the probe function isn't running. How is this possible?

Best,
Jared

Hi Jared, 

My reply got delayed. I was not well, yet again.

If the probe function was not running then how come the camera is working fine in 6.03 SDK. I think the flow of initialization is different in 6.03 as compared to 9.03. 

Anyway, PFA the ov4640.c file for 6.03 SDK.

6472.ov5640.c

You can take take the diff from the 6.03 SDK's original ov5640.c driver.

 Please note that after uploading the driver file, its name got modified as 3247.ov5640.c.

Hi Vishal,

It looks like the registers are set during the stream on/off functions.

Can you run the camera (and start the stream), then send the dmesg logs of the I2C writes?

It would also be helpful if you add a dev_info for when the sensor starts and stops streaming. 

Best,
Jared

Jared,

Jared McArthur said:

Yeah but could you figure out the reason for why the registers are not set during boot? Is it the default design in 6.03 SDK's ov5640 driver ? Was just curious so asked.

Jared McArthur said:

Ok I will send you.

Jared McArthur said:

I guess this is the function for when the stream starts.  Where exactly do you want me to put the dev_info statement inside it ?

Also tell exact statement for dev_info command that is to be run.

I can't see any function for stopping the stream. Please tell the name of the specific function involved in stream stopping along with exact dev_info command to be put inside it.

It's just the way the driver is written.

Keep the dev_info in the ov5640_write_reg function. The ov5640_write_reg function will be called by ov5640_s_stream.

The ov5640_s_stream function both starts and stops the streaming of the sensor depending on the value of enable. You just need to put something like:

dev_info(sensor->i2c_client->dev, "stream enable: %d\n", enable);

before

mutex_lock(&sensor->lock);

Hi Vishal,

Thank you for the logs. If it's possible, it would be helpful to add back the printks/dev_infos to see what registers are sent in the specific functions. For example, what are the resolution registers, AWE registers, etc?

For now though, the differences in the following 2 registers are concerning to me:

They could be the reason for the difference, but it's also difficult to know when the registers are written currently. Some registers are written and overwritten within the logs, and I'm unsure of the reason why.

It would be easier if there are logs to show what is written when.

Best,
Jared

Which printks/dev_infos are you referring to? 

I’m not entirely sure where to place the prints to capture the desired registers' values.

I believe you have a better understanding of when certain registers are written. The reasons behind writing and rewriting these registers would be clearer if the overall flow were known in advance.

Could you please guide me or add the debug prints yourself and share the updated file here? We can discuss it virtually using our indigenous platform or via Microsoft Teams—whichever is more convenient for you.

Hi Vishal,

The general flow of a driver is the following:

1. Driver is probed/initialized
2. Driver begins streaming
3. Driver is streaming
4. Driver stops streaming
5. Repeat 2-4 whenever the camera is told to start/stop streaming

In the 9.03 driver, i2c registers are written in 1, 2, and 4.

In the 6.03 driver, it seems i2c registers are written in 2, and 4. In other words, all of the initialization is done at the start of the streaming instead of on probe.

It's important to know where the registers are written, so we know what registers are for initializing, starting, and stopping the camera.

Ideally, we will observe a mismatch between the initialization/starting registers and that will explain why the output of the camera in 9.03 is incorrect.

Patch for the 9.03 driver:

Best,
Jared

 Jared McArthur , 

Ok on 3rd oct IST morning I will give you the logs for both the SDKs after applying the patches. 

I hope you would want me to retain the existing dev_info prints that you had suggested earlier !!

For 9.03 I will give you boot logs and for 6.03 I will give you prints after camera streaming (same as I gave earlier). 

As soon as you read this reply, do let me know if you need anything else if not above in bold! 

Also, how will these prints at the new location be of much help ? Asking this because you had already  put  dev_info prints in the same function in a different location. What difference will these prints actually make given the fact that I have already shared the logs previously ? 

-Vishal

Hi Vishal Maheshwari,

These patches are assuming the driver has not had any changes previously applied. i.e. the patches contain the previous changes.

I would like the logs from boot to stream to ending the stream. All 4 of the following steps:

1. Driver is probed/initialized
2. Driver begins streaming
3. Driver is streaming
4. Driver stops streaming

Best,
Jared

 Jared McArthur , 

Sure, I will provide dmesg logs from boot to streaming to ending the stream for both the SDKs in some time.

However, in 6.03 SDK, you will see all the extra debug prints that we had put when we had successfully ported the 6.03 camera driver.

I have also noticed that if I removed the printk statements related to those prints then the /dev/video1 doesn’t get created. (I guess due to removal of  delay caused by the prints or any other logical reason that I might not be aware of. To summarize I can't remove the printk statements that have been added over time in 6.03 SDK's camera driver in order to get it working).

So for 6.03 SDK, can you post the diff over the 6.03 SDK camera driver that I have shared with you? It will be easier for me to patch it!

Otherwise I will have to patch your changes manually! (No problem patching manually but it would be faster with the former approach.)

Hope you need me to patch the current 6.03 SDK camera driver (already shared with you) only and not the default 6.03 SDK's camera driver.

Because default camera driver doesn't work. It worked only after the so many modifications we did. We could do the same modifications in 9.03 camera driver but the structure / source code of the camera driver in 9.03  is quite different so skipped that and you also didn't suggest to do the same. 

-Vishal

 Jared McArthur , 

FYI, I had run the command below and I got the output which I have already shared in past replies.

gst-launch-1.0 v4l2src device=/dev/video1 ! videoconvert ! waylandsink

When I ran the above command with -v I found that by default the camera resolution  was set to 1920x1080.

So may be the camera doesn't have proper registers set to open up 1920x1080 resolution.

So, out of curiosity I tried 1280x720 (1MP) as below:-

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=1280,height=720 ! videoconvert ! waylandsink

Here is the output that I got. Basically I am able to see my hand (taking photograph with phone) and a bottle with red cap but partially as the left side is still showing blurred image with only horizontal lines.

I think the issue is with the register values set in various arrays such as ov5640_setting_low_res, ov5640_setting_720P_1280_720 and ov5640_setting_1080P_1920_1080. 

Only register values set inside the array ov5640_setting_720P_1280_720 is able to stream camera and that too partially.

May be the correct register values will solve the problem!

PFA the dmesg logs for 9.03 SDK boot + streaming camera using command below:-

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=1280,height=720 ! videoconvert ! waylandsink

dmesg_camera_TI9.03.txt

Here is the updated patch for my 6.03 modified camera driver as your patch was not on my updated driver and it had compilation error around set_mode function. I have also commented certain redundant prints but obviously** not all.

If your patch over my driver is ready (which gets compiled as well) and if it is dissimilar to my patch above then you can post it here otherwise ignore posting it.

PFA the log file for 6.03 SDK camera (boot  logs+ same gstreamer command as for 9.03) 
6102.dmesg_camera_6.03.txt

Ignore all the prints that are already part of our current driver in attached file above.

**As like I said I can't remove all my previous prints as removing them leads to camera not getting detected as already explained in previous reply. 

-Vishal

Hi Jared McArthur , 

Hope you have read my replies.

This is a gentle reminder, please reply if you have any insights / suggestions to solve the issue.

-Vishal

Jared McArthur ,

I have certain doubts. 

Why only 1280x720 resolution feed is opening and not any other feed like 640x480 / 1920x1080 when running the gstreamer command?

Also after running the gstreamer command for 1280x720 as below, I tried to play with certain registers so that I could get the image to full screen:-

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=1280,height=720 ! videoconvert ! waylandsink

I set the following commands to set the two registers (0x380c and 0x380d) while the gstreamer pipeline/command was running and I got the image below:-

/usr/sbin/i2cset -f -y 2 0x3c 0x38 0x0c 0x06 i
/usr/sbin/i2cset -f -y 2 0x3c 0x38 0x0d 0x00 i

I could not reduce further than this! 

Please help me get it to full screen. Also help me resolve why other resolutions aren't working!

-Vishal

Hi Vishal Maheshwari ,

Apologies, I was out of office.

The timings for the camera are likely incorrect for the specific resolution. You can read section 4-2 of the camera's datasheet for details on setting the windowing registers to the correct values.

You will have to set the correct values for the different windows:

Assuming you're not scaling, the following equations should give your values. The example assumes the X_ADDR_ST and X_ADDR_END are kept at default (entire physical pixel size):

The values are in decimal (not hex).

Best,
Jared
