[iMX8MP] ISP new sensor porting guide

Hi,

I'm in process of research as we are intending to test a few different sensors with iMX8MP and choose the right one for our project based on this SoC. I've choose ov5640 to port and test it first as it is available for the hardware we use - it is capable to output 10 bit RAW over MIPI, so it seems to be good choice. I do NOT want to use the integrated camera ISP as the next sensor to port doesn't have such option.

If this is all successful I can continue with the other sensors as option.

Then I realized the porting guide (i.MX 8M Plus Camera and Display Guide, 2022, Chapter 2) is kind of not very useful as reference what and where to change to adapt different sensor, even if it seems so at first. Also there are some files mentioned in this guide that not actually exist in the isp-imx package, like:

2.5.3 Sensor Driver API
V4l2 Sensor Driver API is declared in file <sensor>_mipi_v3.c , where <sensor> is the name of the sensor (for example, OV2775).

 

Basically all the topics I found in this forum recommends to create a copy of the existing and supported ov2775 files, adjust the code and modify the appropriate files. I've continued in this direction, using isp-imx-4.2.2.15.0 and yocto build system. I should notice that I'm new to yocto (but old buildroot user ) and also new to iMX (but old FPGA SoC developer), so excuse me if I'm asking too easy questions as newbie here.

Anyway, the list of the modified files and directories is:

./units/isi/drv/OV5640
./units/isi/drv/OV5640/source/OV5640.c
./units/isi/drv/OV5640/calib/OV5640
./units/isi/drv/OV5640/calib/OV5640/OV5640.xml
./units/isi/drv/Sensor1_Entry.cfg
./units/isi/drv/Sensor0_Entry.cfg
./units/isi/drv/OV5640/CMakeLists.txt
./vvcam/v4l2/sensor/ov5640
./vvcam/v4l2/sensor/ov5640/ov5640_regs_1080p.h
./mediacontrol/server/CMakeLists.txt
./appshell/shell_libs/CMakeLists.txt
./imx/run.sh
./imx/start_isp.sh

If I understand correctly this will produce the desired .drv file and calibration .xml (which will be dummy/incorrect), the lib files, etc. and will populate the rootfs with them. The calibration will be something to worry at later stage. I will change the appropriate dtb file to support the sensor on one of the available MIPI CSI ports later. Please, let me know if I'm missing something here?

Right now the isp-imx is compiled correctly. But at package_split stage of this package processing the yocto build is returning error related to the position of libov5640.so - it should be in dev, but isn't. So I'm stuck here.

The error output of bitbake is as follow:

ERROR: isp-imx-4.2.2.15.0-r0 do_package_qa: QA Issue: non -dev/-dbg/nativesdk- package isp-imx contains symlink .so '/usr/lib/libov5640.so' [dev-so]

./packages-split/isp-imx-dbg/usr/lib/.debug/libov5640.so.1.0.0
./packages-split/isp-imx-dev/usr/lib/libov2775.so

I'm not sure is it the yocto inducing the problem or I haven't done something properly in the adding the sensor in isp-imx and this is the result?

Some help here, please?

It will be really helpful if someone has added new sensor to isp-imx and is willing to share some repo and/or steps how it is done - it will help all with the same problem to track down their mistakes. I'm quite sure I have done some fatal mistakes until now, which will be fun to debug

Hello @imsOPX , I would like to use the OV5640 with the ISP. Would it be possible for you to share all the files you mention regarding porting this camera for the ISP? Even if they are not fully working, I'd be very interested.

Best Regards,

Hi @ederibaucourt ,

I'm sorry but it is not possible to share the files. Even if they were only for training (before porting the real sensors) - they are still property of my employer. In fact the sensor was working quite well with the basic drivers I have written for the ISP. If you have some specific questions and if I may help you - I will try, just post me a PM.
Have a nice day!

At the end I have the sensor up and running using the IMX8M Plus ISP and the result is quite acceptable. The problems were mostly my errors in the kernel driver module. Well, there is some problem with the AEC feature of the ISP, but I will start another topic for this.

@imsOPX In your previous posts you said the gst-launch presented no errors but no images. How did you solve this issue? I have met the similar problem with you. Thanks sincerely.

 Hi @imsOPX 

It would be really helpful if you can provide some points to my issue.

Im trying to integrate IMX219 with IMX8MP.

Now I'm able to get the video nodes  in the v4l2-ctl command

I think, we will get more debug info from isp-imx if we are able to enable the trace .

Can you please guide on this.

Hi @Amal_Antony3331 

actually I wasn't able to enable the TRACE globally (and I'm sure it will flood you with A LOT  of information). So I did something simpler instead:

// ---> Start of CREATE_TRACER
enum{   IMX_VERBOSE = 0,
        IMX_INFO,
        IMX_WARN,
        IMX_ERROR,
        IMX_QUIET
    };

#define IMX_DEBUG_LEVEL IMX_ERROR

#undef TRACE
#define TRACE(x, fmt, ...)                          \
            do {                                    \
                if( x >= IMX_DEBUG_LEVEL )       \
                    printf(fmt, ##__VA_ARGS__);     \
            } while(0)                              \
// ---> End of CREATE_TRACER

....
TRACE( IMX_INFO, "%s: (enter)\n", __func__);
....

 

Well, it isn't very good solution, but it does the job - controlling the level of debug I'm sorry, I can't help you, may be @khang_letruong will shed some light on to the problem, I think he was successfuly enabled the TRACE? It may be helpful for all of us!

The logs contains some debug prints from my driver as you see, just to be sure the proper functions are called.

Well, so far there is no image.. and I'm thinking what can be wrong. Most probably my ov5640 driver isn't ok, at least to say. I'm using some values from ov5640_mipi.c linux kenel driver init structures, anyway - there are a lot of registers and it is easy to make mistake

Now I see there is something wrong with the max height and width - this sensor is capable of 2592x1944, not 3840x2160, anyway I have tried with 1920x1080, it is still the same result - no error, no image.

As I understand you have ported imx327 to isp-imx, right?

Hi @imsOPX ,

Yes, I did port imx296, imx327, ar0234 and other chinese sensors' drivers with 1440x1080 and 1920x1080 resolutions. Currently, I am porting a 4K one.

Well, as expected, the concrete problem was aftermath of my mistake in the recipe for isp-imx. Always check your FILES_${PN}-dev += ...

Anyway, as this is only part of the process, I will like to left the topic open for further questions related to the porting process.

Hi @imsOPX ,

I am not sure if you have resolved your issue but there's example of how to integrate custom isp-imx into Yocto here : https://github.com/boundarydevices/meta-boundary/tree/master/recipes-bsp/isp-imx

Also, as for your issue I confirm the solution by adding following lines into isp-imx_%.bbappend as below :

FILES_${PN}-dev += " \
   ${libdir}/lib<custom-sensor-name>.so \ 
"

Thank you for your answer, @khang_letruong

Yes, this was the problem, as I mentioned above.

Now I'm trying to understand why it is not working at all. Right now I'm attempting to enable trace prints in my driver as part of the ISP. I already enabled with 1s TRACE( .., .., 1) prints, but nothing shows up/ I'm a bit of confused is the ISP framework calling the correct functions at all? I can see the kernel driver for my sensor up, but the "glue" .drv functions are strangely quiet.

I have disabled the imx8-isp.service and I'm starting it manually with start_isp.sh:

Hi  imsOPX  

I have two questions.  

First is Why did you port Ov5640 to the isp-imx ?  because the driver of the ov5649 is already ported in the kernel source below

drivers/media/platform/mxc/capture/ov5640_mipi_v2.c

drivers/media/platform/mxc/capture/ov5640_v2.c

drivers/media/i2c/ov5640.c 

Did you have any reason to port the ov5640 sensor to the isp-imx package ??

 

Second,  I have a custom board whose cpu is imx8mp, there is a ISP and the imx273 image sensor.

This ISP controls the imx273 sensor thru I2C and i assume i can get image stream thru MIPI and V4L2 buffer.

This ISP provides several functionalities and I2C interface to communicate.

As a result, the control path is different with that of the isp-imx. I wonder I have to port this ISP to the isp-imx package of the NXP ?  

Do you think There is a need i have to port the ISP to the isp-imx ?? 

I want to hear of your idea. i will wait your reply. previously thanks

Hi @imsOPX 

I was trying to port the IMX219 with the IMX8MP. Can you please guide me to enable the traceing in the isp-imx?

Regards

Charlie

Hi again,

For following error:

 

root@imx8mp-var-dart:/opt/imx8-isp/bin# v4l2-ctl --all
INFO   : [MediaPipeline] NativeSensor Creat
[ 1015.143134] enter isp_mi_stop
ERROR  : [MediaPipeline] NativeSensor open error!
ERROR  : [V4l2Event] initialize MediaPipeline error!

 

Maybe you should compare the driver name included in your .drv file (or its source <sensor-name>.c such as OV5640.c) and the driver name in the XML file(s) as well.

Regards,
K.

Hi @imsOPX,

I already enabled with 1s TRACE( .., .., 1) prints, but nothing shows up/ I'm a bit of confused is the ISP framework calling the correct functions at all

Should you also need to export the ISP_LOG_LEVEL=8?

According to my experience, in older version (isp-imx-4.2.2.11.0), it was not straight-forward to enable to tracing by just setting 1s to TRACE() macros. I am not sure if they (NXP) have been more "open" on that in recent versions. Also they confirmed to me that the Full build had not been released to customers : https://community.nxp.com/t5/i-MX-Processors/IMX8MP-isp-imx-Undefined-symbol-trace/m-p/1312440#M1773...

I was able to enable to tracing of isp-imx via their professional support channel, however.

Regards,
K.
