This is what I thought, too.
When I do a
uname -a
I get
Linux IoT_Chalet 4.4.59+ #23739 SMP Sat May 19 03:08:07 CST 2018 aarch64 GNU/Linux synology_rtd1296_ds218play
So to me it is an ARM64 architecture. Any other ideas?
I am running consolewd on another Synology system that has an x86_64 architecture without any problem. It looks to me as if the ARM64 version of consolewd is not entirely compatible or having some components left from the x86_64 version (maybe in the deploy folder).
