Hi, so I tried the PS1 prompt as suggested by André and it worked at that time on the booted system. So I changed the configuration in /etc/profile, built and flashed the system.
Unfortunately it’s not working and I get the same issue - the line wrapping. Here is the content of the /etc/profile: # /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). PATH="/usr/local/bin:/usr/bin:/bin" EDITOR="vi" # needed for packages like cron, git-commit [ "$TERM" ] || TERM="vt100" # Basic terminal capab. For screen etc. # Add /sbin & co to $PATH for the root user [ "$HOME" != "/home/root" ] || PATH=$PATH:/usr/local/sbin:/usr/sbin:/sbin # Set the prompt for bash and ash (no other shells known to be in use here) [ -z "$PS1" ] || PS1="$(cat /etc/device/hwid)@\h:\w \001\033[96m\002# \001\033[0m\002" if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -f $i -a -r $i ]; then . $i fi done unset i fi # Make sure we are on a serial console (i.e. the device used starts with # /dev/tty[A-z]), otherwise we confuse e.g. the eclipse launcher which tries do # use ssh case $(tty 2>/dev/null) in /dev/tty[A-z]*) [ -x /usr/bin/resize ] && /usr/bin/resize >/dev/null;; esac export PATH PS1 OPIEDIR QPEDIR QTDIR EDITOR TERM umask 022 I also turned on `checkwinsize` using `shopt` but didn’t work. I also include the output of stty (over serial): speed 115200 baud; line = 0; -brkint ixoff iutf8 -iexten And over SSH: speed 38400 baud; line = 0; eol = M-^?; eol2 = M-^?; -brkint ixany iutf8 I connect to the board over serial using screen on Mac. In minicom I get the same issue as do my colleagues on Windows using putty or screen on Linux. Same happens over SSH. I also checked that the terming package and those files are installed correctly in /etc/terminfo.
