ftp not connected, bootloader kicking in?

[dionysius]

Dürft gerne in Deutsch antworten. Answers in German are also welcome!

This is my first time trying to flash a fritzbox. I have a 7490 5490 (FRITZ!OS 07.31, firmware 151.07.31) and successfully built a image (standard selection - no modifications except model and version)

When I try to reboot (or pull the plug for 5secs) it always says it can't connect to ftp. I am connected directly with LAN. Currently the fritzbox is configured with 192.168.0.1/24 range and many services are turned off since I don't use them. Does anything need to be enabled for this to work? Or am I missing something else?

My attempts look like this:

$ ./tools/push_firmware -ip 192.168.0.1

   Proceed? (y/[n]) y

 * You should now reboot your box (192.168.0.1). Waiting for shut down.
   Switch off, if reboot is not detected because it happens too quickly.
   Some newer bootloader versions allow to flash on power-cycle only.

Looking at similiar discussions led me to #641, but I had no success forcing it.
I tried ./tools/push_firmware -ip 192.168.0.1 -w -f with a reboot or pulling the plug for 5s and land to the same issue as logged above. Is it a timing issue or something else?

./tools/push_firmware -ip 192.168.0.1

Wenn Du Deine 7490er nicht schon komplett "verbastelst" hast, ist der
bootloader-ftp einer/jeder FRITZ!Box immer unter 192.168.178.1 erreichbar,
unabhängig (!) von "Deiner" festgelegten IP der 7490er.

Du musst also zum pushen ein IP-range von z.B. 192.168.178.1/24 verwenden
(und ggf. auch die IP des push-PCs darin fest vergeben).

Oder eben einfach nur ein:

./tools/push_firmware

dann übernimmt push_firmware das für Dich. :-)

Great, this was an important detail I missed! Also: The linux machine needs to be set to 192.168.178.X even when link is down - so if it comes up, it is ready to connect.

That means I usually ran ./tools/push_firmware -w and power-cycled manually because I was sure the pushing machine was ready.

Off-topic: I accidentally loaded a 7490 image, but I have a 5490!!! Don't ask me how I mixed those up. After a long recovery process it is fixed.
