Compiler/TDA2EX17EVM: yuv video driver and display

mmyan

Part Number: TDA2EX17EVM

Tool/software: TI C/C++ Compiler

Hi,

I have a tda2ex17 development board, I use the vsdk308 development kit, and the compiler choice is MAKECONFIG=tda2ex_17x17_evm_linux_all, the system has been started. The sd card is used to start.

I am not particularly familiar with the vsdk architecture. Currently we refer to the products designed by the tda2ex17 board，Regarding the video input and output changes, the approximate changes are as follows

1、About the video input section

The front end of the camera uses a 913 serializer, and the data stream is in yuv format，Linked to it on the cpu board is ti's 914 deserializer.

2、Video output section

Output via DS90UB921.

I have the following question:

I want to add yuv camera driver and display output driver, I should look at that part, this seems to be different from the driver under pure linux system.

Thanks！

Hi yacc,

Which core controls your sensor? I mean is it A15 or IPU?

In our code, IPU controls this I2C instance, so IPU configures sensor module.

You could look into the code under vision_sdk\vision_sdk\apps\src\rtos\video_sensor\ This code configures sensor, you could add similar way your sensor in vision sdk.

Hi brijesh

I use the development kit of vsdk3.08, the configuration is tda2ex_17x17_evm_linux_all, so I think the driver for the camera should be in the ipu core.

But I don’t know much about the ti multi-core architecture, so it is a bit difficult for the current camera debugging. I hope to get your correct guidance.

Thank you!
