thank you anyway

Maybe it's also because EDS14 has no internal drive ? i use a 64Gb SDcard

yes i know...
is there any log file, that can help me to solve the problem ?

It's the latest for the device : DSM 6.0.3-8754 Update 4
i have tried with Armada370 and with adding the repository
here is the output of uname -a
Linux DATASTATION 3.2.40 #8754 Thu Apr 20 02:24:24 CST 2017 armv7l GNU/Linux synology_armada370_eds14
