It seems gcc 13.2.1 does not compile your code right.

It might be those warning you got, It's doing something different that the compilers I've tried.

From board.h

FYI, I tried to add this to CMakeLists.txt:

Code:

pico_enable_stdio_uart(${BINARY} 1)target_compile_definitions(${BINARY} PUBLIC  PICO_DEFAULT_UART_TX_PIN=20  PICO_DEFAULT_UART_RX_PIN=21)# Serial GPIO means SD card is 1 bit (4 bits otherwise)set(PICO_SD_DAT_PIN_COUNT 1)

And this to simple_start.c:

Code:

    sleep_ms(250);    stdio_init_all();    sleep_ms(250);    printf("*** PT52! ***\n");

These statements work in my projects.

The PICO_DEFAULT_UART_ are already defined in board.h so you don't need them
set(PICO_SD_DAT_PIN_COUNT 1) has no effect the SD driver I use only works in SPI mode

To get output from UART you need to do something like

On the SD card create a file named autoexec and set the system flag
The reason your C code won't work might be that stdio isn't configured to use the UART and printf is overridden
