I noticed that Arduino IDE can output tge detail Information on ELF file etc. while compiling. I think this detail information will be very helpful for studing further about the binary content in the M5Stack Flash memory.
Thank you everybody.

@a-wussow Glad to see you got it working again.

SOLUTION
I found the solution:
You need to follow these steps

Remove all modules, leaving only the host Then try to lower the baud rate when burning If there are wires, you can short-circuit G0-GND before powering on the device and then power on again.0_1711007605157_432299571_430472252787300_1867478767739245481_n.jpg

Hello @poyrazturkoglu

please have a look at the button example here.

I think you are missing an M5.update() inside the loop().

Thanks
Felix

Factory shipped firmware is in M5Burner, code may be in the GITHUB repository.

Hello @ghettokon

maybe related to the note at the bottom here?

Note: 2018.2A PCB version of the device does not support C2C (TypeC to TypeC) connection and PD power supply.

Thanks
Felix

@felmue

BTW i forgot to mention that I also removed those nasty magnets as they disturb the used magnetometer. The metal screws where also replaced with plastic made.

FIXED:

My mistake was assuming the "Configurations" button was essential. If I ignore than and click "Burn" everything is fine.

Hello @Veto6017

hmm, with an M5Stack Fire (HW: 2018.2A) running your code I get "Power canControl OK".

Have you tried to run I2C_Tester.ino? The I2C scan finds 0x10 (BMM150), 0x68 (MPU6886) and 0x75 (IP5306).

Thanks
Felix

Edit:
is there any limit in size for the SD cards ?
if so, what is it ?

Best regards,
C.A.

Hello @codewitch

have you tried keeping it plugged in for a while to charge the battery? have you tried to run it w/o battery, e.g. with the M5GO bottom removed?

Thanks
Felix

@ajb2k3 thank you!

Is the ENV III plugged into the red port?

@ajb2k3 No it's not a Grove pin.

Right, OK, nobody panic!
There is a bug somewhere that causes a random boot loop to appear in the ESP32 and strangely I had this with a Stamp the other weekend.
Disconnect everything and leave the controllers unconnected for a while, cold boot the computer and try and flash UIFLow firmware.
