Reviewing Flashwriter error messages
If during the previous session an error occurred, please check the table below for the recommended
course of action:
Error Message
Recommendation
Unable to establish contact with Marvel CPU,
please try again.
This should not occur if the mvtest program was successful so suggests user
error or bad PC serial port, please try this step again.
XModem TX failure on loading Marvel UART
boot file.
This could be an issue with the PC serial port, check again that this works on
a known good router, if it does and it still fails with this error on a bad router
then request an RMA with reason: XModem TX failure on loading Marvel
UART boot file
Unable to start TFTP
Check that the Ethernet cable is connected correctly and the LAN LED is on.
This error can often be “user error” or “network issues”. However if this error
is repeatable on the suspected bad router but does not occur on a known
good router then request an RMA with reason. “Flashwriter TFTP failed to
start”
Blue progress bar moves, but slowly and with
lots of re-tries and eventually fails.
This suggests a hardware problem or a network issue on your LAN. Check
again that this works on a known good router, if it does and it still fails with
this error on the suspected bad router then request an RMA with reason.
“Flashwriter TFTP failed to complete”
Unable to communicate with device after
reboot
Check to see if the router is continuously rebooting. Please contact Digi
technical support for help.
W-WAN module failed check - please check
you selected the correct module!
Be very careful to check that you are selecting the correct radio module
when you launch FlashWriter. This is the number one cause of this error! If
you are unsure of the type of radio module fitted open the case.
If you are sure you are selecting the correct radio module and if this error is
repeatable on the suspected bad router yet works fine on a known good
router, please request an RMA with reason: “Flashwriter radio check failed.”
