Hello, after contacting M5Stack support the problem is probably the flash chip, M5Stack is replacing my M5Paper.
I had performed this upload test at slow speed but without improvement. Thanks for your help

Hello, i tried the "Factory test" firmware using the M5Burner and EasyLoader_M5Paper_Factory_Test but there is the same message.

Hello,

When I upload an arduino program to M5Paper then there is the following message in the Arduino IDE:

esptool.py v3.0-dev
