Finally we got u-boot with linux working, but I am experiencing problem with telnetd: "telnetd: All network ports in use!"
I've seen around quite a few reports about the same problem but no one solution really works.
Below I attached some info about my system in hope that somebody may be come across this problem.
Thank you in advance for any help.
