    I read somewhere that a bad SD card might have an effect on the camera and cause it to reboot the head unit is this possible

        Mongcharlie Yes. I had this kind of problems because a bad USB drive

            MihaiFlorin i'll get a new micro SD today too to try it out

              Hi, I have a DUDU7 11.5 with 12GB/512GB unit installed a few weeks ago and updated to 3.5. It was working well last few weeks until last weekend when I was doing very long drives for several hours at a time and noticed that it would turn off and then reboot (with the Google boot animation) at random times for no apparent reason. It did it 3-4 times during the day, that I noticed.

              I normally don't have any USB devices plugged into the unit, except for 1 to charge a GPS tracker (power only, no data). This last weekend I did have my phone plugged in to charge a couple of times. And now I come to think of it, I think the random reboots occurred while I had the phone plugged in.

              Later that day I drove back home 3-4 hours and the phone was unplugged and no reboots at all.

              Could this point to the USB errors that could be causing reboots?

                TimF Yes, check the cell phone charging cable and the radio USB cable

                    This is the latest occurrence of the rebooting.
                    the DUDU TPSM was only thing that connected this happened before 10am vietnam time march 1st

                    here is the link to the report
                    https://drive.google.com/drive/folders/10AyGdr1t7wiN0JUVSbYEKwpgr6_cxOgj?usp=drive_link

                    rebooted again mar 1st around 8pm

                        Mongcharlie Is only the TPMS USB receiver connected? Are other USB ports not connected?

                            dudu-lai

                            I label the folders on google drive
                            one folder has the ylog of the reboot with just the tpms connected (happened in the morning)
                            the other folder happened last night, (nothing connected to the USB)

                            is it possible to go back to the last stable version? maybe os 3.0 ? the reboots are inconvenient

                            TIA

                                Mongcharlie I'll submit the logs to the engineer when he gets to work tomorrow, Monday, and if he doesn't have a good idea, I'll tell you how to get back to OS 3.0.

                                    Mongcharlie Still haven't found the cause of the reboot
                                    Please do this, clear the history ylog, connect the TPMS and DVR separately without rebooting, and print a 5 minute log to help us find the USB anomaly issue.
                                    There is no good solution for the reboot issue, the cause is unknown.
                                    Please downgrade back to OS3.0 version, steps are as follows 1: Download OS3.0 version from this link, unzip it to the root directory of USB flash drive (https://drive.google.com/file/d/14M6FXZk2nPzdHyLwyy1pQ1pAYZyQmC82)
                                    2: At the same time, put this file into the root directory of USB flash disk (https://drive.google.com/file/d/1mb2CoCQcstpSPWyB0TxI0wjEj_XQGhHW/view?usp=sharing)
                                    Insert the USB flash drive into the USB port, the USB flash drive will be downgraded automatically.

                                        Mongcharlie OS version 3.0 has the same problem, so you can rule out a system issue. It could be a hardware issue.

                                                            So I found out that it's shutting down because of a thermal issue. It rebooted again today, but I already downloaded ADA 64 and immediately opened it up right after the restart the thermals we're all very high. The temperature drops down very fast and becomes stable at about 45c

                                                                dudu-lai

                                                                Also, I didn't mention this before, but whenever I turn on any app, the fan will start spinning up and turn off.
