"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"

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...

try to remove the FIRE battery bottom

try to erase the flash by M5Burner

then try upload the UIFlow firmware agian.

if still don't work. you could contact the store

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

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!

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

Erase now
