14 Firmware Updating
The CORIOmatrix has been designed for easy updating of both Software and Firmware
to enable new facilities to be easily incorporated into units in the field. The method
requires use of the USB rear connector to upload the new Firmware. Before carrying out
this process the unit must have been powered up and logged into by use of the RS232
port.
Please note:
Prior to upgrading the firmware it is recommended that you save all
configuration settings on the internal SD Card. This is performed via a function in the
application software called ‘Backup to SD Card’ expect this to take a minute or two to
complete.
14.1 Connecting a PC to the CORIOmatrix
To upload the new Firmware a PC should be connected to the Rear USB connector. If
this is the first time the PC is connected the Pc may request drivers to be found, this is for
the Serial Emulator, if these are not available then cancel this stage. The PC will then
find the internal SD Card and will display the Label TVONE. This Drive is used to hold
user files and saved configurations. To update the unit you must drop two files into the
root directory of this drive.
14.2 Firmware File Description
The Firmware for the unit is a single file containing all the sub files required to load the
system. The naming is in the form Mxxx_S34.dat for the CORIOMatrix. The xxx being
the version number.
The SD Card can have many Mxxx_S34.dat files in the root directory. You selects the
desired file by the PLSBOOT file. This file is a 12 character long file that holds in text
form the file to the uploaded. When a new file is sent to a customer a PLSBOOT is also
sent that can replace the existing PLSBOOT in the root directory, you can also directly
edit the PLSBOOT on the TVONE drive to change the text to any of the Mxxx_S34.dat
files.
14.3 Firmware update process
Once the new Firmware file and PLSBOOT file pointing to this file has been placed onto
the TVONE drive you should disconnect the USB cable and return to the RS232 control .
From the command line type
Coriomax.software_update()
The reply should show that the PLSBOOT has been found and that it is loading the
Mxxx_S34.dat file.
The process then checks the file for integrity and will start Erasing the FLASH.
Files are then deleted and replaced. A message stating update successful will be shown
followed by a rebooting of the system running the new Firmware. If it fails at any stage a
command TVONE> prompt will appear.
