Description

The default example is supposed to print two lines then let the user type the commands, but on the Nano 33 BLE the two lines are not printed correctly and some characters are mixed in the shell input which imply that the user has to erase them.

Steps to reproduce the issue

With a Nano 33 BLE linked to the computer :

BOARD=arduino-nano-33-ble RIOT_TERMINAL=picocom make -C default flash term 

Note that I'm using picocom instead of pyserial which doesn't change anything to the result.

Expected results

The output is clean with the lines printed in the right order and the input is empty and let the user type his command without erasing anything.

The output is supposed to be the following one :

main(): This is RIOT! (Version : 2024-)
Welcome to RIOT!
>

Actual results

The actual output is :

Welcome to RIOT!
> mai):Th is

The first line is not printed and instead seems to be partially sent to the input of the shell.
