The board does not have android. Anyway this is just an evaluation, the
real board that I will be working on
will come a few months later and that will have Ethernet (ssh) support.

Do you have the procedure to run any simple job in Jenkins using qemu
emulator just for a demo purpose?
I tried the fix you gave before to fake the logging (please find below a
snippet of the log after changing the DISTRIB to distribs/nosyslogd.dist),

+++ echo 'cmd: echo Starting test Functional.hello_world >>
/tmp/fake-syslog'
+++ ov_transport_cmd 'echo Starting test Functional.hello_world >>
/tmp/fake-syslog'

but the test still fails with the below message,

+++ case "$TRANSPORT" in
+++ sshpass -e ssh -o ServerAliveInterval=30 -o StrictHostKeyChecking=no -o
UserKnownHostsFile=/dev/null -o ConnectTimeout=30 -p 22 dhinakar at 172.17.0.1

Fuego error reason: Unable to drop filesystem caches

Build step 'Execute shell' marked build as failure

Permission issue, but the ssh user 'dhinakar' has sudo permission.
What else could be the reason?

Thanks a lot, at this point I will rather change the board or qemu instead
of making it work on serial.
I hope it will stabilize in a couple of month, I can probably try that time
if needed.
