linux.bin

- Compared to previous cut from last week, this
one has DHCP on LAN ports working all right.
- Enabling of WAN port does not break LAN anymore!

I did not test any advanced functions, but it seems
that LAN/WLAN swithching and routing are now OK.

- WAN port is still broken: even with static IP
address it seems to be unreachable for LAN/WLAN hosts.
- DHCP client is dead on WAN port.

wgt624v4-firmware.bin

- Loading it through "Firmware upgrade" page in dd-wrt web interface failed
on last write block saying something about file length mismatch.

Confirming test results:

WLAN client can see and connect to LAN host.

I assume this means that switch works as supposed.

Web image update was weird - it took 15-20 minites to finish
because flash writes occured in small chunks of 64Kb.

Web UI reported update error at the end.
Timed out?

I installed it into flash

Neither exec nor go work - Redboot freezes trying to
read partition named kernel.

ok some pages go i saw u posting that u exec a part called kernel. this will not work for us Wink
plz do
Code:
fconfig

then it asks for somthing like "exec on boot command". this is set to "y"
ack this.
then it asks for the boot commands with 1 empty line in the end
fill in
Code:

fis load -l linux
exec

then go on about 7 times then it will ask u for saving to flash...ack this with "y"
now it should boot automaticly

I tried everything you suggest and it is not working (here is the log):

RedBoot> fconfig -l
Run script at boot: true
Boot script:
.. fis load -l linux
.. go

...

RedBoot> reset

...

check kernel checksum...



Note the last line I highlighted.
Boot freezes on this command, which is not in boot script!

I think that running checksum is hardcoded and can't be changed in Redboot configuration.

P.S.
Replacing "go" with "exec" in boot script did not change anything.
It still freezes in the same place ...

ok is see. it checks kernel checksum....sh**

ok then we need a new redboot. i will speak to BS to get it managed. btw dir300 ap61.rom will not work cause it has a different switch.

Ok so if im understanding the current state of where we are.

1. People without a serial need a firmware that allows configuration/replacing of redboot that can be flashed via stock firmware/web interface. Or just to add a serial connection.

2. Need a slightly augmented .rom to allow replacement of redboot or a way to fake the checksum.

so if both of those are met we are more or less up and running minus minor bugs that we will have to hammer out in the long term?

Overall, we need the following major things:

- new boot loader
- fix in firmware for WAN port

Access to serial port is not that important.
You may manually flash bootloader and firmware using telnet and TFTP.
Besides, once you have raw images for RedBoot and firmware,
compiling them into web-loadable image is a matter of minutes.

Well i bow to your superior knowledge. But i haven't seen any evidence to being able to put the router into recovery mode( i think thats what its called) if so what ip address does it use so i can give it try?

To enter RedBoot command mode:

Once you have RedBoot command prompt, you may try
to upload firmware:

Upgrading bootloader is trickier and I would not try it until we have new bootloader ready.

Ok you just made me feel real dumb :/ i was trying to gain access via the WAN port like all the dir300 tuts say.

Either way thank you very much Very Happy but i cant seem to get it to load using the instructions from the link you posted. Im assuming thats how you load it but it just freezes up then drops the connection after i run exec or go.

Im probably just missing something stupid again. If you can point me in the right direction its appreciated. But if i distracting you from getting it fully working for everyone else just ignore me.

If you completed all steps in these instructions including creation
of linux partition ("fis create linux") - then you should be all right.
Linux resets all ports and you should loose your telnet conection
when it starts.

After you start linux, hold reset button on you router for 5-10 seconds
and release it. The device should reinitialize nvram settings and restart.
Enter RedBoot command mode again and run linux as you did before.
After a while you should be able to see dd-wrt configuration page
at your router's address http://192.168.1.1.
