ESP32 Forum

Hi

In the hello_world project I changed only one line from printf("Hello World!\n"); to printf("Hello XXXXX!\n") and built all once again.

I do not understand why there is no effect after flashing my ESP32 module (ESP32 DEVKIT V1) - after connecting the module with putty still I see Hello World

There are no errors everything seems to be ok.

Something is wrong but I do not know what.

Regards
Artur

Hi Arturs,

I don't know what is wrong, either. Maybe you have two copies of the source file, and updated the other one?

If it's still not working, please modify the source file again (add an extra X or something) and then post the full output of the build and flash commands here.

Is it possible that it's booting firmware in an OTA partition? Erase entire flash and try upload again.
