UART 4 logging while connected with st link.Also what does this means : LD Linker > Libraries > Small printf?

[darla14]

Hello,

There may be another variant of this question available but I am reposting it as I couldn't get any success so far redirecting prinf messages to uart4 and viewing them on serial terminal utility.

below are the snapshots which shows I have mapped the PUTCHAR method, configured UART4 in the fw and also the serial port utility is having the same connections but I am not able to get any data on the terminal.

 

 

 

The code has a comment: LD Linker > Libraries > Small printf > am I missing this step? Where do I have to do this in the IDE Settings?

Regards,

D

Any update on this. Is it even possible to get the logs while we debug simultaneously on the ST LINK port? Just like in NUCLEO Boards.
