PROCESSOR-SDK-DRA7X: Linux SDK dra7xx-evm-vision.dtb Missing

Emily Birch

I am trying to use a DRA7xx-EVM kit with a VisionSuper28 breakout board to access the video input from the HMDI transceiver on the VisionSuper28 daughter board. The DRA7xx-EVM kit is running the default image/filesystem from the v6.00.00.03 automotive Linux SDK. In the SDK developers guide, it says that a specific device tree blob file needs to be select to allow for the vision device drivers to be selected by U-Boot. However, the file that the dev guide specifies (dra7-evm-vision.dtb) does not exist in the rootfs generated by the SDK. Does any one know where I can get the correct device tree blob, or if that fails, the drivers themselves to manually install?

Thanks

Hi,

Yes, The dra7-evm-vision.dtb is not available in the PSDKLA 6.03 version & This is expected because this SDK version is not stable, We didn't test any vision application & it's supported only SD boot mode(QSPI, EMMC boot is not supported), etc.

We don't have a plan to add these features to this SDK version, so recommending to use the previous version of the SDK otherwise you have to implement yourself by referring to the previous version.

Thanks

Hi,

Thank you for your response, where can I find the older SDK release binary? The SDK page for the DRA7xx processor does not show any links to get past releases.

Thanks

Edit: The older releases can be found here https://processors.wiki.ti.com/index.php/Category:Processor_SDK_Linux_Automotive
