TDA4VM: OpenVX single cam AWB error during execution

David Dominguez Moises

Part Number: TDA4VM

Hi,

I'm currently using the single cam app from the basic demos from vision apps, which seems to use the open VX stuff. I can see image correctly showing on my display but the console outputs the following messages:

[MCU2_0] 14175.543287 s: VX_ZONE_ERROR:[AWB_TI_process:1495] TI_AWB_do Returned error 1
[MCU2_0] 14175.543364 s: VX_ZONE_ERROR:[tivxAewbProcess:812] AWB_TI_process returned error 0xffffffff
[MCU2_0] 14175.571032 s: VX_ZONE_ERROR:[AWB_TI_process:1495] TI_AWB_do Returned error 1
[MCU2_0] 14175.571094 s: VX_ZONE_ERROR:[tivxAewbProcess:812] AWB_TI_process returned error 0xffffffff

Any idea on what could be going wrong?

To create my sensor driver a copied on of the existing drivers (AR1040) and modified the respective sections. Havent tuned the DCC ISP stuff yet.

Thanks,

David

Hello David,

It seems to be an issue with input arguments to AWB algorithm. Can you please add prints just before TI_AWB_do function is called? I want to see the values of

p_awb_params->ti_awb_data_in.frame_data.h3a_data_x

p_awb_params->ti_awb_data_in.frame_data.h3a_data_y

Regards,

Mayank

HI Mayank, I will get back to this tomorrow since I'm trying to bring up the sensor driver for a different camera module I have.
I have posted a related question since I see some similar error message coming from OpenVx app. Would appreciate if you could help take a look at that one.
