is it because the jtag-uart is not on receive mode so the code stuck in the printf() function?

This could happen if you selected in the bsp configuration the Small implementation of the HAL drivers, for reduced code footprint.

The default settings in the bsp is the Fast implementation, which checks the jtag connection status and it will avoid the interface to get stuck when nobody is receiving jtag output data.
