Linux/TDA2EX17EVM: BT656 For TDA2Ex

Part Number: TDA2EX17EVM

Tool/software: Linux

Dear Sirs:

  We use latest Processor SDK Vision.

  We want to make sure the BT656 is really working on TDA2 so we did the following test:

1. We use J6E Board with a VAYU VISION board with the OV10635 sensor

2. When using BT601 with OV 1063x setting  setting 0x4700 and 0x4708 inside the PSDK, the code working fine.

3. When using BT656 with OV 1063x setting setting 0x4700 and 0x4708 inside the PSDK and modify the related OV video setting to be

a)pInstPrm->videoIfMode   =   SYSTEM_VIFM_SCH_ES;

b)pPortCfg->syncType          =   SYSTEM_VIP_SYNC_TYPE_EMB_SINGLE_422_YUV;

and other setting remain same as before i.e.

pInstPrm->videoIfWidth  =   SYSTEM_VIFW_8BIT;

pInprms->dataFormat =   SYSTEM_DF_YUV422P;

pInprms->scanFormat =   SYSTEM_SF_PROGRESSIVE;

... Please refer to PROCESSOR_SDK_VISION_03_02_00_00\vision_sdk\apps\src\hlos\common\chains_common.c where captureSrc == CHAINS_CAPTURE_SRC_OV10635

The above OV BT656 setting is working in our DM81xx board, but not in J6 Entry.

  Do you have any idea to know what could be the problem to no VIDEO input in BT656 mode?

Regards,
