    I have noticed two recurring scenarios when flashing OTA OpenBeken:
    BL602:
    Flags (Current value=1207960576)
    NTP driver loaded.
    After successful OTA flashing, a strange chip temperature reading appears: the temperature changes every second between about -40°C and +40°C.
    After a reboot the reading returns to normal.
    After changing flag 2 without a reboot - also returns to normal.
    The problem has been recurrent after every OTA flashing for a long time.

    BK7231N, Tuya WiFi sockets with current measurement (BL937, CB2S), NTP driver loaded:
    During flashing the chip crashes (flashing addresses stop not far before the end).
    After unplugging the chip starts with the previous OTA version.
    After enabling flag 36 and rebooting the OTA can be updated.
    I have replaced the chip in one of the slots with a WB2S (swapped P6 with P8 in the configuration), but have not yet checked how the OTA behaves without flag 36.
    I noticed that the problem occurs with large autoexec.bat files also on CBLC9 and CBLC9S - circuits without current measurement. I have replaced the capacitor on the power supply, but I don't think that's it.

    .
    And if you do a "stopDriver *" while the device is running, i.e. stop the drivers, the OTA works too?

    It sounds like the operation of the driver - which driver? - spoils the OTA

    Does the problem occur without NTP?
    Helpful post? Buy me a coffee.

    Flag 36 does not disable NTP - because NTP is in autoexec.bat, it disables BL937 instead. It looks like there is a lack of resources when flashing. It's even worse with SetupEnergyStats enabled.
    StopDriver I didn't do, I'll check with new firmware.
    Generally, clearing autoexec.bat removes the hang on flashing.
    I will check the behaviour of BL602 without NTP with new firmware.
    I have the chips: CBU and CB3S, which do not hang on flashing despite the large autoexec.bat and the current NTP.

    Edit:

    BL602:
    stopDriver ntp; I clean autoexec.bat to zero,
    OTA start...
    Moments before reboot negative temperatures appear, after reboot is fine.
    I upload the contents of autoexec.bat - temperature starts to go crazy after reboot
    StopDriver NTP - negative temperatures continue.
    Restart all - NTP module starts and temperature is OK.
    In the OTA 160 version the problem is back.

    Flash to version 154 with NTP enabled - this time OK, temperatures are correct.

    CBLC9S:
    I did a stopDriver NTP ... OK
    OTA start (version 153) ...
    Addresses saved to the end, then automatic restart, started up for a while and stood at something like this:

    At this point the controller responds correctly to buttons and scripts from autoexec.bat, no web page.
    After powering off and on everything is OK, no errors in the log, the OTA is in a newer version.
    Could it be that the NTP driver is spoiling WWW access?

    I checked the flash to version 154 (file size changed? Flashed: 07AFFFh). It works with NTP enabled.

    It remained to check the slots with NTP and BL0937 drivers:
    CB2S with drivers enabled and SetupEnergyStats disabled from version 152 to 154 with no problems, although it briefly stopped at address 000FFFh.
    WB2S (BK7231T chipset) with drivers enabled and SetupEnergyStats from version 152 to 154 disabled stopped at address 075FFFh (as if the WWW stopped working, rebooting in the background), but then the driver already reported with the new version and is working.

    It remains to check SetupEnergyStats with the next version:
    WB2S (BK7231T) flash to versions 155, 156 and 158 works without problems.
    CB2S (BK7231N) flash to version 155 failed, but web access returns automatically with old OTA version. Disabling SetupEnergyStats - still no effect.
    Disabling NTP in autoexec.bat - also no effect. Flag 36 - it worked (BL0937 disabled). NTP enabled with flag 36 - worked - flash to version 156 and 158 succeeded.
    Log on failed flash to version 160:

    Then a break and logs of the booting system.
    One other thing I noticed - the 40 flag is on in both sockets, and still the result is in Wh, not kWh.

    Another issue - temperature. The CB3S chip, previously flashing OpenBeken, lost the firmware after the spill, but the settings remain. For now I have 1 unit for testing.

    Now disabling NTP and rebooting does nothing, constant temperature all the time. Broken sensor?
    Flash to version 156 - no change. Maybe not exactly: for a few minutes after a hard reboot (disconnection of power supply) the temperature oscillated around 39°C, then jumped to -45.5°C and did not change anymore.

    I obtained another CB3S, first sflashing via UART, then several OTA versions (lowest 129, highest 158) and still the same:
