Hi, we have approx 150pcs of rut240 running in the field with our clients. The issues we have seen is that the device randomly crashes and all leds stays/go on. Restarting the device manually be removing the powerplug, wait for 10sec and plug the power back in solve the issue for a while, sometimes hours, sometimes days, updating the bootloader solve this issue for not happening again.
And yes we have tested multiple firmware versions even the latest firmware version, but this is not a firmware issue but a bootloader issue and an update of the bootloader will solve it.
Offcourse all new devices already have bootloader 3.0 or higher.
However in the rms tool you cannot check the bootloader version, thats why it is very helpfull for us if the bootloaderversion is saved in the rms management tool.
