This step by step guide to upgrading the software in Flowire through its serial interface only applies to software version PLC-1.2.1.

For newer version jump to Upgrading through web interface

Requirements

The following equipment is required to perform the upgrade:

USB-Serial cable

A special USB to Serial cable has to be used for the software upgrade. The cable can be made out of two items:

With these two items, make an adapter cable which connects the debug connector of the Flowire to the USB port of the PC:

Flowire cable


  • On the Flowire, connect to these pins:
    • Pin 7: GND
    • Pin 8: TX (Transmit) – Connect this to Rx on the serial cable
    • Pin 16: RX (Receive) – Connect this to Tx on the serial cable
Flowire pinning


PC setup

  • Set the IP address of your computer to 169.254.1.2, subnet mask 255.255.255.0:
Set static IP address 169.254.1.2 on your PC


  • Connect the USB-Serial cable to the USB port of the PC
  • In the Control Panel, open the Device Manager to see which serial port has been assigned. It will be listed under Ports (COM & LPT) as USB Serial COM port #x, where x represents the COM port number. Double click it and change the port settings from 9600 baud to 115200 baud.

TFTP server setup

  • Start the Tftpd program on the PC
  • From the main window browse to the folder where the software files are stored. Choose the PC LAN port as the server interface:

Physical setup

  • Do not connect the power supply to the Flowire unit yet
  • Take of the top lid of the Flowire by unscrewing the two screws
  • Locate the JTAG and connect the cable, cable pointing away from the PCB
  • Connect the PC to the switch using an ethernet cable
  • Connect the Flowire to the switch using an ethernet cable

Telnet setup

  • Open PuTTY
  • Choose Connection Type Serial, change Speed to 115200 and make sure it has the right COM port number:

Version check

By running this command you can see the current software version: 

cat /proc/net/plc/version

Upgrade

  • While holding down the space bar (or actually any key), power up the Flowire. You should see data in the command window. Once you see data, release the space bar.
  • Enter these commands, one at a time, and press [Enter] after each command:
    • setenv serverip 169.254.1.2
    • setenv ipaddr 169.254.1.10
    • protect off all
    • tftp 0x40100000 u-boot218.bin
    • erase 0x30000000 0x3002FFFF
    • cp.b 0x40100000 0x30000000 0x30000
    • tftp 0x40100000 jffs2-spc
    • erase 0x30040000 0x3013FFFF
    • cp.b 0x40100000 0x30040000 0x100000
    • tftp 0x40100000 linux-spc
    • erase 0x30140000 0x3049FFFF
    • cp.b 0x40100000 0x30140000 0x360000
    • reset


TIP! Mark the text line and copy it (right click > copy, or Ctrl+C). In the PuTTY window right click with the mouse and the text is instantly pasted. Hit [enter]. Copy/paste one line at a time.

  • When the Flowire is back online you can login with root.
  • By running this command you can see the new software version:
    • cat /proc/net/plc/version
  • The procedure is now finished. The Flowire can be disconnected and the next unit can be upgraded.

Upgrading through web interface

Flowire units with software version zenitel-rel-4.00 can be upgraded through the web interface.

Setup the system, and TFTP server in the same way as described in these chapters

Use a standard web browser and type http://169.254.1.10/goform/zForm_stn_upg in the address field.
