Fire with UIFlow2

a.wussow

Hi all,

i'm new to the M5Stack universe. I got my Fire 2.7 today and tried to upload the UIFlow2 Firmware for fire.
Flashing is working well (i also get a success message, hash was verified, ....), but the device is dead after flashing.

On the serial monitor i can see that something is corrupted:

I also tried different version, but without any success. Is there any possibility to work with the Fire and UIFlow2?

Thank you very much!

Best,

@a-wussow Did you use M5Burner?
Did you erase before burning?
Did you select the correct firmware version?

@ajb2k3 Thanks for your response.
Yes, i used M5Burner and also tried erase before burning.
I selected "UIFlow2.0 Fire".

But in the meantime i worked with Arduino IDE and tried it again. After flashing with Arduino, Erasing with M5 Burner and Flashing again with M5 Burner its now working. Strange ...

Thank you.
