  • In Modify the BW1098OBC to add an ESP32 System on Module

    Hi @sanjith ,

    Thanks for getting it! And sorry about the delay. Somehow my notifications from our own forum are going to SPAM in my mail client... trying to figure out what I misconfigured.

    And yes, the camera is already connected to the Movidius directly. So you can also use the BW1092 board that has integrated ESP32 directly over USB to visualize results as well.

    So yes the link you are referencing is the current version to use. It's the first proof of concept. We have since made it better and have the capability to store the .blob file onto the onboard NOR flash (the .bin and .xml are converted to a single .blob which is stored to the board). The engineer responsible for this is in Europe, so he's not online now. But we will provide this tomorrow.

    Sorry again about the delay. Also feel free to join our Discord community - we are often much faster to respond there to technical questions/etc.

    Thanks again,
    Brandon

    Hi @sanjith ,

    So SPI support is still under development. So right now the code (binary running on the Myriad X) and model are still being loaded over USB.

    And then the SPI communication is done after the device is booted over USB.

    So we are in the process of ordering future designs which will allow DepthAI to boot over NOR flash (and then also eMMC, but a different model). See here for example of a board with integrated ESP32 and NOR-flash boot. And then we also do have extremely limited number of NOR-flash-boot samples for interfacing with other embedded systems now here. The high price is temporary while the stock is so low... we don't want to stock out.

    So later there will exist the capability for a SPI controller to load the neural network and binary code to DepthAI over SPI. We have not written this yet.
