Retarget printf on STM32G070RBxx Cortex M0+

[AVerm.4]

Hi,

I'm trying retarget printf. My uart_write function is working correctly and i'm able to see character on Teraterm.

But when i try to use printf it is not working. i even tried semihosting to execute printf but it fails. i'm attaching the screenshots -

Disassembly of the code stucks at "bkpt 0x00ab" -

any solution for this problem?

1. How to do it in C++
2. Notes on the line buffering

Addendum:

Maybe also some details on the input side of this - maybe as a separate article?
