Standalone mode oak ffc 4p does not work

Hello, I have some trouble with flashing my programm on my board for standalone mode. After flashing it without an update of the bootloader (it was version 0...

Maimilian For that, I believe it would be best to open feature request on depthai-core, that even USB bootloader can access eMMC memory (currently, only NETWORK bootlaoder can). I also don't think flashing BoardConfig (needed for UART) is available, perhaps creating separate feature request for that would be useful as well.

Maimilian

erik Is there any chance that flashing config for uart will be available in the next two weeks?

Maimilian

erik where should I create a feature request?

Maimilian

erik And another question: is it possible to use network bootloader with the oak ffc 4p?

Maimilian

erik Or is there any other way to work without a Computer?

erik

Maimilian It's always suggested to write concise and thought-over messages 🙂

It depends on the opportunity. If you could share the volume opportunity here (or email support@luxonis.com) we can expedite this. Commitment (to buy) may be required. If this is a bachelors thesis then I don't see this being implemented even in 1 year, but if there are 1000s pcs/year opportunity then we would fix this over the weekend. I hope you understand.

No, I don't think so.
No, standalone mode is the only way.

erik Thanks for all your help! We decided to use a raspberry pi to have a non standalone mode on the board.

erik

Maimilian Also to set board config (to have an effect in standalone mode), you could use pipeline.setBoardConfig(config).

Maimilian

erik I think this solution sounds good as well. However, I have to use config=dai.BoardConfig() instead of config=dai.Device.Config(). Do you know how to set the GPIO pins and the uart in this case? Thanks for your suggestions!

erik

Hi Maimilian ,
dai.Device.Config.board is an object of the dai.BoardConfig. So:

boardConfig = dai.BoardConfig()
boardConfig.gpio[int] = GPIO(...)
pipeline.setBoardConfig(boardConfig)

Maimilian

erik Makes sense. What could be a possible index instead of int? Is it my uart number? And what do I need to write into GPIO(…) because I have to set the rx and tx port

erik

Maimilian yes, you could use exactly the same as the code you posted above.

Maimilian

erik Thanks a lot! I think config.version is then unrelevant as there is no attribute version, isn‘t it? 🙂

erik

Yes, correct🙂

nem

hey @Maimilian did you have any luck getting this working in standalone mode?

Maimilian

nem Yes, it worked. Just go through the steps mentioned above (e.g. compress =true). Feel free to write back in you have any further questions

Hi, i'm also interested in using the ffc-4p with SoM-Pro for prototyping. The datasheet says the ffc-4p uses the SoM-Pro, which has 128MB of flash, so could someone please explain where the 16MB limitation discussed above is coming from?

erik

Hi rmaxwell , due to supply chain issues, some SOM-Pros have 16MB of NOR flash and instead have additional eMMC flash (eg. 16GB). You can check that using https://docs.luxonis.com/projects/api/en/latest/samples/bootloader/bootloader_version/#bootloader-version
