Description

Hi

I have some example RP2040 code that works in the Ardunio IDE without fail. When ported to Platform IO the code fails on the following:

Serial.printf("timers_init failed - %d\n", err_code);

src/main.cpp: In function 'void loop()':
src/main.cpp:22:10: error: 'class arduino::UART' has no member named 'printf'; did you mean 'print'?
   22 |   Serial.printf("timers_init failed - %d\n", err_code);

This works in the ardinio IDE.

Thanks

Research direction

Start with src/main.cpp at line 22 and reproduce the RP2040 PlatformIO build error involving Serial.printf. Compare the PlatformIO Arduino serial implementation with the Arduino IDE behavior; done should mean the reported example builds and the formatting call works, or the supported alternative is documented.
