        No one got interested? it seems the manufacturer were trying to release dev resources, but there is no activity so far( https://openone.dxo.com )
        I bought used one and somehow does not function properly; no wireless connection (and other issues)
        Now I'm trying to open up and poke inside of firmware system, but I have some experiences with linux systems, but not with reverse-engineering things.
        If I can open up this device, try some UART connections, but no luck so far.

          Some interesting stuff can be done using an autoexec.ash AmbaShell script file.

          For example this command sets the bitrate to 30Mbps: "t svc json set_setting 2 30000000"

          And this one lets running JSON commands: "t svc json run_cmd '{\"token\":, \"msg_id\":, \"param\": \"c\"}'"

          pretty amazing! i found potentially relative ambashell commands for xiaomi/gopro cams. I'll try more until i get linux shell. (still want to know list all available comamnds/ or redirect ambashell output to file; date > c:\date.txt just doesn't work )
          appreciated!

          I managed to disassemble dxo one; but couldn't find any accessible debug pinouts like uarts
          Meanwhile, using autoexec.ash, running 'help > c:\help.log' yields ambashell output to sdcard. Previous attempt didn't work because I didn't make empty line at the end of file.
          There are suspicious commands in t command, like 'dxo', 'remote', 'wifi', 'usb', 'eng-mode', 'test-mode' but couldn't find built-in help docs.

          Inside .bin firmware update file, I found some linux to rtos commands and debug scripts are available. So embedded linux access will give us much more access to device itself.

          hope dxo releases official docs on openone.dxo.com

        babinch Here is the unpacked ROMFS fw sections: https://my.pcloud.com/publink/show?c...3nwB8zqLlzTiwX

        Many interesting files are there like calib6.bin and calib13.bin which are distortion and chromatic aberration correction profiles.

        babinch Have you tried changing the 'capture mode' (type 6)? Are these working modes for the SuperRAW HDR?

          I just tried; set_setting 6 2 didn't work for SRAW. It worked more like a burst mode with raw. But set_setting 69 1 worked, dumped .dxo file in DCIM with jpg file

          Oops...... I bricked my DxO One
          It's on firmware update process and it looks like trying to find AmbaSysFW.bin file in mSD card.
          But I don't know how to extract "AmbaSysFW.bin" part from DXOCARD_3.2.0.ecef5ef809.BIN
          Any idea you have?

            I'm not sure if it's a good idea, but have you tried renaming DXO*.bin into AmbaSysFW.bin? It usually works with other Amba cams...

            BTW there are three more possible fw names:
            AmbaUpdaterFW.bin
            DXFSD.bin
            DXFSDFULL.bin

            If nothing helps there should be some kind of recovery mode to flash it via a PC connection.

            Now I'm trying to enter recovery mode to connect PC

            If shutter and/or reset buttons do not work when USB is connected maybe shortening one of test points near TX/RX on the PCB would do the job.
        Working...
