8.2 Error handling
This chapter will list all the possible error codes that can occur dur-
ing an upgrade error. The error code will be visible on the feedback
webpage. If an error occurs the device will not reboot itself au-
tomatically. Instead it will wait upon user action. This is to allow
the user to take the next step. E.g. the user might want to check
some parameters before rebooting or try to run the upgrade pro-
cedure again.
Failed to download firmware file from server
Error code: -2
The user should verify the IP address and the image filename. If
any of them is incorrect the user should go back and submit the
correct parameters at the main html page (index.html). If the pa-
rameters are correct the user should verify that the TFTP server is
running on the host computer and that the TFTP server settings
are correct.
Host not responding/No contact with host computer
Error code: -3
The user should verify that the host computer is connected to the
encoder. The ping command can be used for this purpose. If con-
nected, go back to upgrade.html and click Confirm to try and up-
grade again.
Checksum Error/File image error
Error code: -4
Calculated checksum doesn’t match the one supplied by the im-
age file. The most likely cause for this problem is that there was
an error when downloading the file to the encoder. Go back to
upgrade.html and press Confirm and try again.
Flash Erase/Write Error
Error code: -5
The image might be corrupt. Flash Erase or Write failed. If this er-
ror occurs the device can still start with its failsafe image. It will be
displayed by the Execution State parameter on the web Page.
