Updating the Boot Code
13. Type y at the prompt. Do not press the Enter key. You will be prompted to transmit
the boot code file as follows:
Start transmitting new bootblock file.
14. Promptly start the upload from the terminal emulator by pressing the PgUp key,
selecting ASCII, and then entering the file name to be uploaded.
The upload process takes approximately one to two minutes. When the upload has
completed successfully, the following message is displayed:
Programming in progress...
Default console speed is 9600
For several seconds, the AWAN access server reprograms Flash ROM with the new
boot code, then automatically reboot itself.
15. Change the terminal emulator baud rate back to 9600. When the AWAN automatic
reboot is complete, the console port is set back to 9600 8N1. If the terminal
emulator is not changed to 9600 baud in time, the console port output might not
appear, or it might appear garbled.
16. If the new bootblock version is displayed on the console port, then the update was
successful, and you should now update the runtime code using either a terminal
emulator or TFTP. (See Updating the Runtime Code Using a Terminal Emulator on
page 14-31 or Updating the Runtime Code Using TFTP on page 14-32.)
17. If the old bootblock version is displayed, then the update failed. Retry the procedure,
starting at Step 3, using successively slower baud rates.
18. If nothing displays on the console port, or if the display is garbled, verify the
terminal emulator: Set the baud rate to 9600 8N1 and perform the following steps:
a. Wait 10 seconds.
b. Power the AWAN off.
c. Wait a second.
d. Power the AWAN on.
If the new boot code version is displayed, the update was successful. If the old boot
code version is displayed, retry the update at successively slower baud rates.
After several attempts, if nothing is displayed on the console port, then the boot code
stored in Flash ROM has probably been corrupted, requiring you to return the unit to
the factory for hardware reprogramming.
Caution. If you take too long to send the file, the file contents of hexadecimal data will be
echoed to the screen and you must restart the procedure. During normal upload, either nothing
or a periodic ... is displayed.
Caution. Do not power off the AWAN at this time. Removing power before the reprogramming
of Flash ROM is complete can render the unit inoperable.
