Hey @mcmordie the reboot command isn't fully supported yet, its something we're working on and hope to release soon. I'll post an update in this thread once its released :)

[mcmordie]

OK thanks-- makes sense

[hughbreslin]

Hey @mcmordie the reboot command should now be functioning with the latest release of the Yocto BSP and HSS if you want to update to the latest reference design release and yocto image :)
