SK-AM62A-LP: How to tune VPAC parameters online through DCC tool and how to add new sensor driver?

Part Number: SK-AM62A-LP

Hi, TI experts, 

I followed the quick start guide of AM62A  and successfully captured the video stream through app-edgeai.py. 

But I have a few questions:

1) How can I connect the AM62A board to PC and tunne VPAC parameters using DCC tool online?

2) After flashing SD card .wic image and booting linux through an SD card, how can I add a new sensor driver to it?

best regards,

    DCC tool online tuning is not yet supported in SDK 8.6. Please refer to the AM6xA ISP Tuning Guide for how to tune AM62A VPAC parameters.

    Please refer to the same document provide above, specifically chapter 5 - Sensor Software Development and Integration.

    When could AM62A  support live tunning through DCC tool？

    Hi Jianzhong, 

    In the  AM6xA ISP Tuning Guide, adding a new sensor driver needs to revise /opt/edgeai-tiovx-modules/src/tiovx_sensor_module.c and /opt/edgeai-gst-plugins/ext/tiovx/gsttiovxisp.c. 

    While in TI's guide Academy for AM62AX (3.11.3. Use Camera — Linux Academy for AM62AX (ti.com)), it mentions adding a new sensor driver  needs to add specific driver files to drivers/media/i2c directory, revise the Makefile, etc; and then rebuild kernel and cp to the EM. 

    So If I want to add a new sensor driver to AM62A, do I need to conduct all the steps mentioned above? Is there any other steps that I should do? 

    Best regards, 

    Jianxiong

    Hi Jianxiong,

    Yes, you need to follow the instructions from both documents:

    • AM62A Academy provides steps to add a new sensor driver regardless of using ISP or not. For example, some camera modules have in-built ISP and do not use the ISP on AM62A. For this case, the AM6xA ISP Tuning Guide is not needed.
    • AM6xA ISP Tuning Guide provides steps to add support for the new sensor to GStreamer plugins so that ISP can be used for the new sensor.

    These steps are all you need to take.

    Regards,

    Jianzhong
