Linux/TDA2PXEVM: [vision sdk 3.05]Linux porting TIDL OD usecase fails to create display

Part Number:TDA2PXEVM

Tool/software: Linux

Hi, 

I am engaged with TIDL OD usecase  Linux porting. The difference with original case is that  the usecase itself and nullsrc link run on Linux OS,  tidlpreproc on IPU .

Other links, the input files and config file are the same for the two case.

[IPU1-0] 46.905508 s: TIDL Configuration parameters
[IPU1-0] 46.905599 s: -----------------------------
[IPU1-0] 46.905660 s: inputWidth = 768

[IPU1-0] 46.906118 s: threshold = 0.300000
[IPU1-0] 46.906209 s: -----------------------------

But I encounter the below error for the linux case.

[HOST] [IPU2 ] 75.435673 s: dssPrms(Width 1536, Height 640, posX 192, posY 64, type 0), dssPrms->inFmt(width 776, height 328, pitch0 776, pitch1 776, pitch2 776)

while for successful TIDL OD run on BIOS, the log is as follows.

Seems the resolution and pitch value of dssPrms->inFmt for linux case is not correct. I have no idea what may cause the problem.

Can you help suggest something? Thanks a lot!
