DVEVM DM36x example applications

Hello, Texas Instruments,

I try to launch capture example applications from dvsdk (capture_prev_rsz_ss_raw_yuv).

It gives:

----------------------------- 

 input.name = Composite
InitDevice:ioctl:VIDIOC_S_INPUT, selected Composite INPUT input
Input video standard is PAL.

S_STD Done WITH std = 255
SetDataFormat:revpfe-capture vpfe-capture: width = 720, height = 576, bpp = 2
questing width:-vpfe-capture vpfe-capture: adjusted width = 720, height = 576, bpp =

2, bytesperline = 1440, sizeimage = 829440
1097704484 height:-1097704488
davinci_resizer davinci_resizer.2: Operation mode doesn't match with current hw mode

S_FMT Done
initializing capture buffers

REQBUF Done
Capture initialized
opening resize device
Can't get operation mode
: Invalid argument

---------------------------

What does " Operation mode doesn't match with current hw mode " mean? How assist this? 

The exact question is how to diagnose such problems without turning to E2E Community always, is there any sheets describing properly all setting of u-boot, modules, inputs and outputs? 

Thanks in advance.

    Hi,

    I looked into capture_prev_rsz_ss_raw_yuv.c file, the previewer itself is not configured in here.

    What does " Operation mode doesn't match with current hw mode " mean? How assist this?

    Operation mode means single shot or continuous, currently in the application resizer is configured to

    single shot (IMP_MODE_SINGLE_SHOT) and previewer is not because of which you are getting the above

    error.

    In which operation mode do you want to run it?

    If its single shot run the do_preview_resize application.

    Thx,
