Part Number: TDA2PXEVM

Tool/software: Linux

Hi,

I got this hardware below.

a. TDA2Px EVM x 1
b. Fusion Card/EVM x 1
c. TIDA OV2775 cameras (with Fakra cables) x 1

I can capture the image from OV2775_TIDA1130 in Linux in vision_sdk with ISS Usecases, (TDA2Px ONLY)/1CH ISS Capture + ISP + DISPLAY. Now I want to port my customer camera.Before that, I want to learn the framework. And I think this usecase is good to use.

At first I thought the driver sources is in vision_sdk/apps/src/rtos/iss/src/sensor/ov2775 .But it seems I was wrong, I modified the code, and rebuild and copied the app.out to evm and ran it.It didn't work as I wanted.

I compared the md5 of app.out before modify and after. It hasn't changed.

So,Which source files do OV2775_TIDA1130 use?

Thanks and Regards

Hi,

Did you also change code to configure OV2775? I mean the configuration is part of vision_sdk\apps\src\rtos\iss\src\sensor\ov2775\ov2775_linear_1920x1080_setup.h header file, did you change this?

Please note that these drivers are supported from IPU, so apps.out could remain same..

Rgds,

Hi Brijesh,

I don't change configure file of OV2775.I just add some print statements in Void IssSensor_OV2775_Tida1130_Init() and other function in iss_sensor_ov2775.c.But it didn't print when I ran it.

Example

Void IssSensor_OV2775_Tida1130_Init()
{
    Int32 status;
    IssSensorIf_Params *prms = &SensorParams_Ov2775;
    IssSensor_Info *info = &SensorParams_Ov2775.info;

    Vps_printf("enter IssSensor_OV2775_Tida1130_Init\n");   //I add this

    IssSensorIf_Params_Init(prms);

    ...............
}

So,if I change the code,which output file should I update to target evm?

Hi,

Since you have updated init API, this prints would be available in boot log. could you please check your boot log?

Hi Birjesh,

My statements did print until I update all the files of filesystem.So I do confirm I do not update the right out files.

So if I don't want to update all the files,what file should I update when I change the code?
