When i first got it it was working fine. I followed the manual that can be found on the link
http://image.openvox.cn/
to flash another .img file under the name USB4UC.zip.
My problem is, after following this process i cannot boot (hear the beep and access via ssh) into any OS besides Debian. I've already tried with the following files:
Issabel4-ver20180102-uc-hwdetector-20180706
UC-Series-3.2.2-20190401-OPVX-AutoRecover
centos7.3-16g-uc-20170822
Debian-9.8-UC-20190907 (The only one that works for me)
They all appear to complete the process correctly, but i can only access de device after completing the process with the Debian file.
