RTOS/TDA2HG: HW SHORT occurred on TDA2 vision-kit and de-serializer board when 4 Cameras were connected

Sung-IL

Part Number: TDA2HG

Tool/software: TI-RTOS

Dear Champs,

My customer failed to run SV demo with VisionSDK_UserGuide_TDA2xx.pdf using pre-built image. When they connected 3 cameras, there was no issue to run DEMO, but they failed to run DEMO with 4 cameras. At this failure, they observed high 'current' in their power supply like HW SHORT.

So, they sent de-serializer board to repair it, but they failed again even with new board.

Could you please let me know your idea what should be checked in this case?

SW is Vision-SDK v3.02.00.00.

Thanks and Best Regards,

SI.

Are they tried 2D SRV on TDA2x EVM + Vision daughter card + OV10635 Camera ?

or any other demo.

Please check they used the right power supply (the one shipped along with EVM kit)

Hi Shiju,

Yes. they tried 2D SRV on TDA2x EVM + Vision daughter card + de-serializer board + OV10635 cameras.
There was no power supply in the EVM package, and they used power supply.

Thanks and Best Regards,
SI.
