"Timed out waiting for packet header"

[F3l1x]

Hi
Trying to follow an official M5 tuto, I want to upload the arduino code to the Fire board.
I get a time out error. Full message :
Arduino : 1.8.1 (Windows 7), Carte : "M5Stack-FIRE, Enabled, Default (2 x 6.5 MB app, 3.6 MB SPIFFS), 115200, None"

esptool.py v2.6
Serial port COM26

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

I tried many baudrates, with no luck
Some people say it is because we need to hold-down the “BOOT/FLASH” button while uploading ...is there a simple way to do it with the Fire board ?

Sooooo...
The arduino code did upload - I don't know why!
But the program did not show anything so I tried to edit it, and now it won't upload.
So I thought it was something about the USB mode. Unfortunately, I don't have the setup option anymore
So I tried burning the 1.6.2 firmware again...M5Burner fails with this message:
Chip is ESP32D0WDQ6 (revision 1)

Burned failed

I feel so stupid...

Thanx...everything back to normal
Is there a way to mark topic as [solved] ?

[F3l1x]

Oups...not solved at all
It did it again and again. Won't flash from arduino IDE

I did erase and reflash firmware...fail again
I'm getting mad at this Fire thing
So promising and so disappointing!

[F3l1x]

Getting worse...M5burner won't even erase now

Erase now
