I got a new camera with this chip, I dumped the contents in the SPI flash and looks like this is some variation of the XR872 chip from XRADIO
Magic at the beginning of the flash matches “AWIH” and there are also references to this SDK GitHub - XradioTech/xradio-skylark-sdk: Xradio wireless MCU rtos SDK，supporting XR872 and XR808
Pinout looks different, this chip is QFN-68 (17 pin per side) and all other XRADIO chips are QFN-40 or QFN-52, can be a custom one, or a new one that is not documented yet…
