problem with PRINTF()

Nadia — Thu, 14 Jan 2021 14:41:10 GMT

Good afternoon,
I'm using a LPC54616 and I have a problem, I put the instruction PRINTF, and I don't get anything out of the console, I have chosen the Newlibnano library (semihost) and I have taken the floating point, I don't know what happens.

If someone has had a similar problem and knows how to solve it, I'll thank them.

Greetings

Hello, thank you very much for your quick answer, I have everything set up as a semihost, and I can't print anything on the surrounding console.

If you want to use semihosting, use standard C printf() and not the PRINTF macro.
