Second channel cutting when REISZER OVERFLOW OCCURED

Expert 1840 points

Hi all,

I use ipnc3.5. Our Camera is working normally, but whenever the error REISZER OVERFLOW OCCURED happen the D1 (second stream) was cut. It look like the resizer B didn't work correctly after ISS reset. Please watch 2 below image for the detail.

I looked through the issdrv_captureApi.c and Int32 Iss_captResetAndRestart(Iss_CaptOverFlowStatus * overFlowStatus) function. However, I couldn't figure out what happen here.

Thanks  a lot.

    Hi,

    The function Iss_captResetAndRestart() is replica of the function Iss_captCreate().
    When resizer overflow occurs we need to reset the complete ISP.

    Can you print the values of 'rszB_reg->RZB_V_DIF' and 'rszB_reg->RZB_H_DIF' at the end of the Iss_captResetAndRestart() function?

    regards,

    Hi,

    Thank you very much for your reply. This is log for two values which you mentioned.

     [m3vpss ] VIDEO IN - Reset: rszB_reg->RZB_V_DIF = 256; rszB_reg->RZB_H_DIF = 256; isif_reg->PPLN = 1280; isif_reg->LPFR = 720

    Hi,

    It looks like you have printed the addresses of 'rszB_reg->RZB_V_DIF' and 'rszB_reg->RZB_H_DIF'.

    Can you add the below print function at the end of Iss_captResetAndRestart()?

    Vps_printf("rszB_reg->RZB_V_DIF = %d,rszB_reg->RZB_H_DIF = %d\n",rszB_reg->RZB_V_DIF,rszB_reg->RZB_H_DIF);

    regards,

    Hi,

    I am sorry, I made a mistake.

     [m3vpss ] VIDEO IN - Reset: rszB_reg->RZB_V_DIF = 256; rszB_reg->RZB_H_DIF = 256; isif_reg->PPLN = 1280; isif_reg->LPFR = 720

    Hi,

    The settings rszB_reg->RZB_V_DIF = 256 and rszB_reg->RZB_H_DIF = 256 means that the Resize ration is 1 and Resizer B is not doing any resizing.

    Can you print the same values in Iss_captCreate() fn.

    Can you pl.check the following points?

    • Is ''rszBSetOutConfig()' called in 'Iss_captResetAndRestart()'.If yes then print the values of 'pObj->createArgs.scParams[0].inWidth','pObj->createArgs.scParams[0].inHeight','pConfigSizes->nOutSizeBX' and 'pConfigSizes->nOutSizeBY'.
    • What is the sensor used?
    • Does it hit the 'rszA_reg->RZA_V_DIF = 256;' statement anywhere in the 'Iss_captResetAndRestart()' fn?

    regards,

    Anand

    Hi,

    - this is log in Iss_captCreate() fn: [m3vpss ] VIDEO IN - create: rszB_reg->RZB_V_DIF = 256; rszB_reg->RZB_H_DIF = 256

    - ''rszBSetOutConfig()' is called in 'Iss_captResetAndRestart()'. I printed out the value which you mentioned:

    [m3vpss ] VIDEO IN - Reset: rszB_reg->RZB_V_DIF = 256; rszB_reg->RZB_H_DIF = 256; isif_reg->PPLN = 1280; isif_reg->LPFR = 720
    [m3vpss ] VIDEO IN - Reset: pObj->createArgs.scParams[0].inWidth = 1280; pObj->createArgs.scParams[0].inHeight = 720; pConfigSizes->nOutSizeBX = 720; pConfigSizes->nOutSizeBY = 480

     

    - We used the IMGS_OMNIVISION_OV10630 sensor, but I don't think the reason came from sensor type because everything is working normal now, and the main stream video data has no problem.

    - yes, this statement rszA_reg->RZA_V_DIF = 256; state many place in  Iss_captResetAndRestart() and the value of it was fixed.

    Hi,

    In my code i see that for IMGS_OMNIVISION_OV10630 for the resizer B the following settings are used:

     

    rszB_reg->RZB_V_DIF = 380; //1280/720*256;
    rszB_reg->RZB_H_DIF = 450; //720/480*256;

    Pl. find the code attached.

    Can you compare it with yours?

    regards,

    Hi,

    what you have already point out is correct. this problem came from wrong value of rszB_reg->RZB_H_DIF and rszB_reg->RZB_V_DIF. In our previous code, we applied the formula which I saw somewhere in TI's code as below

    rszB_reg->RZB_H_DIF = (isif_reg->PPLN / 720 * 256); // isif_reg->PPLN = 1280
    rszB_reg->RZB_V_DIF = (isif_reg->LPFR  / 480 * 256); // isif_reg->LPFR = 720

    the problem is the order of * and / is not suitable. I correct them to 

    rszB_reg->RZB_H_DIF = (isif_reg->PPLN * 256) / 720; // isif_reg->PPLN = 1280
    rszB_reg->RZB_V_DIF = (isif_reg->LPFR * 256) / 480; // isif_reg->LPFR = 720

    I really appreciate your help. You saved my life.
