Hi Laurent,
My best guess is that it was built on lubuntu which uses glibc, but the Udoo
board doesn't have the required /lib/somewhere/libnss*.so libraries - those get
chosen at runtime based on /etc/nsswitch.conf. Building using a uclibc cross
compiler would avoid that - how did you build it? Also which distribution does
Udoo use?
If you can install strace on the Udoo board you can see what files are being
tried with
strace -f -F -o logfile -s 300 dropbear -vFE
Cheers,
Matt
