@themusicman I had this happen to an M5Station but nothing else.

@themusicman This is "The Community" website supported by user volunteers.
You should raise an Issue over on the M5Stack Github page,

Hi Terry, sure will do. I simply followed the links on the official M5Stack page where 'Forum' is listed under the 'Explore' menu hence considered this an official forum of M5Stack. There's no indication on the M5Stack page that this is anything other than an official page of theirs, quite misleading many would agree I am sure, especially considering each of the other links on that page head to official M5Stack pages such as GitHub, News, YouTube etc.

In any event, many thanks for the clarification that this is a site run by the community, that's good to know.

Also, unfortunately, on GitHub I see infrequent replies to issues posted. It appears M5Stack are not particularly supportive to customers when it comes to official replies to issues. I've returned a device to the company I bought it from which was purchased only last week due to what appears to be a strange and possible design issue where the M5Core2 device is unable to be placed into BOOT mode in order to recover/restore factory settings. At £45... bricked after a week is not something I expected for what is essentially a very high spec ESP32 board!

The issue I have overall with M5Stack is that their devices are not cheap low cost £3.50 ESP32 boards, they are quite expensive items relative to what they are and as such M5Stack don't appear to run an acceptable official after-sales support service. This makes this community even more valuable.

Thanks again Terry.

@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:

Thanks for the advice.
it works for me too.

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?

thank you for the reply ill try comenting that piece of code and see if it compile.

@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!
