Hello everybody,
would like to report an error on the ESP32 with mongoose Release 2.12.1.

After this update (mos update) and updating the mos-libs with: git pull, now at (commit 69d868cb705fe64b1f14f2f7a0345e13efa9dc90)
my device (esp32) is entering in a reboot cycle with the following message:

the build command was:
mos build --clean --local --libs-dir ../../../../embeddedSoftware/esp32/components/ --verbose --platform esp32

Does somebody have similar problems and if, how could you resolve the issue?

    If i let away the closed source components of the mos-libs and i compile the firmware with the
    mos version (2.11.0) "mos update 2.11.0", then i don't have any problems with this reboot cycle.

    Even when i try to keep away the closed source components of the mos-libs with the mos version (2.12.1)
    i only see repetitive reboot cycle like described above.

    Working firmware build with mos (2.11.0):
    mos build --clean --local --verbose --platform esp32

    Not working firmware (reboot problem) with mos (2.12.1):
    mos build --clean --local --verbose --platform esp32

    The problem with the reboot cycle after the update from 2.11.0 to 2.12.1 was with a faulty flash chip on the ESP-WROOM32 on our testsystem. After exchanging the ESP-WROOM32 module on our hardware the newly built firmware with the 2.12.1 version is again working.
