NMP – User Guide, Version 3.00
Updates
The NMP can be updated in two different ways. Remotely via the RTCU device, or locally by
accessing the SD card.
Remote update
The NMP can be updated after it is deployed, by sending the update file through the RTCU
device.
This is done by transferring the
update.zip
file to the file system of the RTCU, and then
calling the
nmpUpdate
4
function, which will transfer the file to the NMP device and start the
update. Transferring the update to the NMP device takes a long time due to the connection
speed.
SD Card update
With physical access to the NMP, it is possible to update directly via the SD card, providing a
faster transfer speed. To perform an update, remove the SD card from the device, place the
update.zip
and
update.xml
files in the NMP folder on the SD card, reinsert the card and
start the NMP device.
Update process
Once the update has been transferred to the NMP, it will either ask the user if it should be
installed, or install it immediately, depending on the type of update. If the update is postponed
or is interrupted, it will try to install it again the next time the NMP starts.
