cam2ip VS bouffalo_sdk

a quick google search found cam2ip which claims to be able to do what you want. I would focus on putting my effort towards figuring out a program that can do what you want and not a specific distro :)

You can access Camera2 API via NDK since API ver 24, for devices that do supports it. I tried to do something here but never finished https://github.com/gen2brain/cam2ip/blob/master/camera/camera_android.go. Before that, I successfully used a camera with native access from OpenCV 2, but that is only on very old devices, can't remember exact API versions. For everything in between I believe the only way is to access the camera from Java, then pass that via JNI or something like that.

One trick could be done by using this docker, and pass through your USB webcam to it

I bought a bunch of the 16Mbit flash variant for an embedded project but sadly it looks like the firmware always gets corrupted on write, and have gotten no reply from Bouffalo

I tried looking through the source code of the SDK to get somewhat of an understanding, but it's taking too long for me to understand, so I'll leave it in your hands. gpio.h gpio.c gpio_reg.h

BouffaloLab has recently started bringing order to the chaos. They have created a new bouffalo_sdk where they're merging bl_mcu_sdk and bl_iot_sdk, the latter being the one to use for wireless. The README file lists which peripherals are currently supported. There's still work to be done, but it's good news they engaged into this endeavour.

The chip has complete-ish sdk here(https://github.com/bouffalolab/bouffalo_sdk) we use as "documentation". Datasheet and the reference manual are incomplete.

I don't think there is a "common solution". From my point of view, the Bouffalo Labs chipsets are not yet widely in use, at least not outside of china. However - as far as I can see, the USB host example code from the SDK interfaces the USB HID parts of the stack, too: https://github.com/bouffalolab/bl_mcu_sdk/blob/master/examples/peripherals/usbhost/usb_host.c

I just scoured the current main branch of https://github.com/bouffalolab/bl_mcu_sdk and can see the current HAL supports DMA, EMAC, flash, GPIO, MJPEG, PWM, RTC, encryption, timers, UART and USB. DAC and ADC's (audio) are implemented but not tested. I can also see there are BSPs for the LP core if you wanted to take advantage of it, with helloworld examples for all three, and finally there are some examples of using TensorFlowLite in the examples directory that you could build and try too.

Wifi/RF on bl616 is the same state as bl808. We are waiting for bouffalo to release support for it in bl_mcu_sdk: https://github.com/bouffalolab/bl_mcu_sdk/issues/85
