Part Number: TDA3XEVM

Tool/software: TI-RTOS

Hi Everyone ,

I am trying to generate a new branch in rear view panorama usecase with following links and chain :

IssCapture -> IssM2mIsp -> IssM2mResizer_Capture -> Alg_drawRearview -> Merge_Mosaic -> Display_Panorama

Compilation was successful , however when I tried to run this on TDA3X EVM board I am getting error in creation of Alg_drawRearview link id in priv.c .

I have checked the set create params and the link id , I dont find anything wrong it .

Kindly help me in resolving the issue

Hi Surendar ,

On which core have you enabled Alg_drawRearview

Hi Chetan,

I have tried in both DSP 1 & DSP 2 cores , for both the cores creation of drawRearview link id is failing

have you included the algo in the usecase cfg.mk file .?

when you run make -s showconfig
you should see the alg in
Alg plugins included in build
Alg_drawRearview

Please include the same and try

Hi Chetan ,

Sorry I didnt mention this before , I have included that algorithm in usecase cfg.mk and now i checked in "make -s showconfig" too . It is showing that alg plugin is included

# Alg plugins included in build,
# ALG_autocalibration ALG_deWarp ALG_dmaSwMs ALG_drawRearview ALG_rear_view_panorama ALG_remapmerge ALG_sceneobstruction ALG_surroundview ALG_iss_aewb

the alg gets init in the following file
apps/src/common/app_init/app_init_dsp.c

#ifdef ALG_drawRearview
Int32 AlgorithmLink_DrawRearview_initPlugin(void);
#endif

Please introduce a error in the condition and verify the init is successful.

Hi Chetan ,

I will check and get back to you on that

Hi Chetan ,

I am getting compilation error when I made changes in the file you mentioned

Hi ,

That ensures the alg is created .
You will have to debug if there is any failure in alg create .

Hi Surendar,

Another think to check, this algo links supports only YUYV and YUV420 format. Please check if the format is correct.

Also please check maxWidth/maxHeight provided in the create parameters is not less than the resizer output width.

Also have you included GRPX link in your usecase? Please include if it is not.

HI Brijesh ,

the data format for ISS is SYSTEM_DF_YUV420SP_UV ,
I have also set the max width and height of draw rear view to 640 , 480 respectively as similar to ISS params
Yes , I have also included GRPX in this usecase .

But still I am getting assertion in creation of draw rear view link id .

Hi Surendra,

Could you please share the assertion location? i think it prints the assertion file and line number on console.

yes sure ,

Hi Abhishek,

ok, it seems it is not able to find algorithm link itself.
Are you running Alg_drawreadview link on IPU or DSP? Please note that default core selected for all links is IPU, so you need to explicitly specify DSP core for this link. Can you check this in your text file if it is set to Alg_drawRearview (DSP1) ?

Hi Brijesh ,

Previously , I didnt mention which core for drawrearview , but now I have mentioned as you said . But I am facing the same issue .

IssCapture -> IssM2mIsp -> Dup_Initial -> IssM2mResizer_Capture -> Alg_drawRearview(DSP1) -> Sync_DmaSwMs -> Alg_DmaSwMs -> Merge_Mosaic

Strange, have you made sure that the algorithm is included and included in DSP1?
Which SoC you are trying to use this algo on ?

Hi Brijesh ,

I have done the following to make sure that algorithm is included ,

1) added alg plugin in usecase config file
2) enabled alg_drawrearview in vision_sdk/apps/configs/cfg.mk
3) its already added in DSP in the file /vision_Sdk/links_fw/include/link_api as below

ALGORITHM_LINK_DSP_ALG_DRAWREARVIEW = 38,
/**< Alg to copy i/p frame to o/p frame */

4) made sure that it is also reflecting in make -s showconfig
5) as suggested before made alg_drawRearview algorithm to run on DSP1 core

and I am using TDA3X SoC . Please Correct me if I missed any of the things or I am in the wrong path.

Hi Abhishek,

Please check
1, if ALG_drawRearview macro is defined in your links_fw/include/config/apps/tda3xx_evm_bios_all/system_cfg.h config file?
2, if AlgorithmLink_DrawRearview_initPlugin from apps/src/rtos/alg_plugins/drawRearview/drawRearviewLink_algPlugin.c is getting called
3, if the DSP map file has functions of this link included in it.

Hi Brijesh,
I am also facing the same issue, can you just explain the last point (3.if the DSP map file has functions of this link included in it.). I am not understanding it.
