Hi

This question has probably been asked many times but because the site search engine returns 0 results :

compiling sprintf(...,"...."...);

linker returns : undefined reference to __io_putchar

I have checked and small printf no-floats is selected, UART0 - No

Thanks in advance

Thanks - sorted out UART0 must = YES

problem it adds over 4K code and 280bytes data - double my project size.

have to find a simple printf version.
