Failed update esp32

Hello, i’m tring to update my esp but i’ve this problem in all my esp (32- 8266).
In the attachment the error, what can i do?

Read the release notes - especially breaking changes…

It is not very easy for me to set the new modification, so what i have to change in my code?

so what i have to change in my code?

I don’t know - you haven’t shown us your code. I don’t use UART in any of my devices so I can’t really post an example.

That said, it seems you can’t use uart0, uart1 etc as a device ID any more. Change it to uart_0, uart_1 etc.
