Printf's not working and Path to add new library files

[iamraoakash]

Respected all,

I have a STM32 Nucleo L073 MCU and I want to use a I2C pressure sensor.
I have LoRaMAC 4.5.2 and according to the path it is build correctly as there aren't any errors as can be seen in the screenshot below.

Now as per the L073 board.c file the UART is initialized with 921600 baud rate, 8 Data bits, 1 Stop bit and No Parity.

and I am using Tera Term with the same configuration, it can be verified in the screenshot below:

Now as can be seen, when I upload the .bin file as it is built I see some things being printed on the terminal but the printf statements don't work as intended (as I have written it in the main.c file)

Please help me in figuring out as to where the mistake has been made from my end.
Also I would like to know that if I want to add custom header and .c files at what location should I add the files?
