NSA Firmware Update Screen
As the NSA-Expanders are smart devices with their own microcontroller it is possible that any
Firmware might need an update for new functions or bugfixes. This can easily be updated through
the NerdSEQ.
The NSA update screen has the following functions:
- Rescan NSA → This will try to rescan connected expanders. This might be needed after a
firmware update or if it was not recognized correctly in the begin, or if you don’t know which
firmware is running on it. Be aware that expanders should only be connected while the power is off.
- NSA Address → Set the channel of the expander that needs to be updated. It must match the
channel which is selected with the jumper on the rear side of the expander.
- NSA Type → The type is entered automatically when an expander detected. otherwise it will be
filled in when loading a firmware file
- Firmware File → Opens a file browser to select a firmware file for the update. For the update one
must copy the firmware file into the /firmware folder of the SD card. All .nxp files are possible
update files. Furthermore, a connected Video Expander can be updated too. It’s file is always
named ‘KERNEL.IMG’ and the NSA Type and Address is being inserted automatically.
- Update Now → If all was fine, then update now can be selected. It will check if the connected
expander type is correct and more information. On success it will start to flash the firmware. Do not
remove the SD Card or power off the NerdSEQ/Expander while updating. And do not worry if that
happens either. If an expander is unresponsive in normal operation, you can try to flash it again.
Just remove the power of the expander and connect it. Now you got less than a second to press
the Update now button and it will flash the expander again.
If an update is executed successfully then it will be indicated and NerdSEQ rescans all NSA. Here
you can check the new version number. If something went wrong an error message is shown and
NerdSEQ does not rescan the expanders. Try again or check out what the issue is.
Sometimes it might be also be necessary to power cycle the expander before it is recognized by
NerdSEQ after flashing, even though if it showed a success message.
