    I don't know which battery it came with as I have several in a pile from a few cams.

    For once DebugIO (PA9) and DebugCLK (PA10) are correctly labelled so a backup can be taken with those - see topic C-SKY Flash Programmer with STM32 CK-Link Lite: Reading/Writing to Taixin TXW817-810 MCU for firmware backup instructions. BUT note that PA10 is shared with the blue LED so almost immediately the GPIO switches to flashing the LED. Precise timing is required to catch the firmware before it boots far enough to change GPIO function. In the T-Head Debugging Server once connected:

    Do you still have it?
    I remember you used a different one in dev thread.

    yes. there might be another variation or two too. I have only tried on that X6 PCB to date. Also want to try on the TXW816 Otoscope

    Added after 1 [minutes]:

    and to see what might be involved in adding more cam drivers. One of the cams is a Hynix HI704 which I don't see a driver for in the Taixin SDK. The other Otoscope user looks like his came with a HI708

    That might not necessarily mean that it's not supported (even though it most likely isn't).
    I have one GC0310 camera - and it worked, even though there is no mention of it in SDK.
    (Init sequence for GC0310 (https://www.elektroda.com/rtvforum/topic4121965.html) looks like GC0312 (https://github.com/NonPIayerCharacter/OpenTXW81X/blob/main/sdk/lib/bus/iic/sensor/sensor_gc0312.c))

    OK sure.

    here's another, my first https://www.elektroda.com/rtvforum/topic4033757.html#20946310

    that would explain why both worked at this stage when I think only one of the drivers was defined

    and now for OpenTXW817

    not yet got any modules detecting/streaming an image, log as txwcam is started with the sensor this shipped with (below), the SuperPix SP0A19 LT1757-OA-10 V1.0

    the mic seems be OK when rtsp streaming. I'll flash back factory to be sure connector on PCB is OK.

    damnit. the connector seems OK.

    Camera app interface with microphone enabled and blurred lens view

    don't tell me these things have multiple pins to choose from on the TXW817 chip 😡

    been playing quite a bit as you may see from commits. no joy yet.

    most pins do seem to be routed somewhere. awkward for multimeter tracing is that the IC is on the opposite side to the cam connector

    I see that after PB_8/9 no other pin combinations are checked.
    Remove it from array and check again?

    Did you attempt to trace it? Camera pinout is known (https://github.com/daniel-dona/beken7252-opencam/issues/9)

    will do, if I can get back to the working scanner code ;o

    negative. not yet. mostly because of:

    but I'm sure I could get a thin wire on SDA right at the end. surely.

    I am aware of that diagram yes, and started one time to map it out in my own head and check it against a cleared XF16 PCB. Don't know why I didn't finish
