  @chuck808 said in M5Stack Core2 Factory Test Timer: Hello, I realise this is probably a dumb question, but has anyone split the Timer function and screen from the factory test? I've spent a couple of days trying but not having much luck, though I have got the numbers and bar graph to show but not functioning. I am using Arduino IDE. Thanks Did you manage to achieve this, Chuck? I’d be interested to find out. I’ve just today received my m5core2 and am starting to dive into the code. Great documents, nice libraries, nice product but poor support on here I’m finding. It’s a shame.

  @caccum Well, speaking personally: I believe the BootLoader is deep inside and indestructible. I would use Arduino IDE to upload this basic LCD sketch: https://github.com/m5stack/M5Core2/blob/master/examples/Basics/display/display.ino

  Hello, @wsanders The app0 and app1 partitions are used for firmware update with rollback in case of failure. It is also used by the OTA function. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/ota.html

  Have you got all the libraries imported? 5.1 and 9.19 mean that they haven't been defined or the libraries not imported or that you are compiling for the wrong device.

  @davidjmcclelland If you connect to the core using M5Burner then click on the yellow "config" button to change boot up.

  This has not happened since I posted this question so I am going to mark it solved. I also got an answer to question 2 and am off and running with the device despite not getting any answers here.

  Thanks Yes, I want to be able to build a firmware file with MicroPython & LGVL. How do you cross compile for the ESP32? How do you then make the firmware image?

  @zontex it looks like there has been an update to Bluetooth on UiFlow for Core2: now it appears BLE Central and BLE peripheral options. Do you know what the difference is? Thanks! Alvaro B.
