AM62A7: How to save h3a data on AM62A?

Hi TI experts,

Is there a way to save h3a.bin file on AM62A?

We can press "s" to save "Sensor RAW, VISS Output and H3A output" when the camera app is running on TDA4, but the method of lightening camera module on AM62A is different from TDA4, "Sensor RAW, VISS Output" can be captured using DCC, while the H3A output cannot be obtained through DCC.

Note: The AM62A board using is custom-made by ourselves rather than EVM board.

Hi Zhili,

This feature is not available on AM62A. Regarding H3A output, did you mean the data printed here: https://git.ti.com/cgit/processor-sdk/imaging/tree/ti_2a_wrapper/src/ti_2a_wrapper.c?h=main#n826?

If that's what you want, you'll have to modify and rebuild the imaging code according to this FAQ.

Regards,

Jianzhong

This seems to be the H3A data we want, do you know how to store it as a file?

Thanks.

Hi Zhili,

The TI 2A wrapper runs on A53 core Linux, so you should be able to use fprintf to save the data to a file.
