Hi all,
I got my trusty old wgt634u to successfully boot OpenWrt 15.05 with the
help of a serial cable and some experimentation.
The wiki/toh page for this device mention that it does not automatically
try to flash an image from TFTP when it boots.
I wondered why this is, actually.
Although the *default* configuration of the WGT634U does not try a TFTP
flash, it is definitely possible to configure it for automatic TFTP flash
from the serial console. In the CFE bootloader I ran this:
CFE> setenv -p STARTUP 'ifconfig eth0 -addr=192.168.1.250 \
-mask=255.255.255.0; \
flash -noheader 192.168.1.1:wgt634u.bin.0 flash0.os; \
flash -noheader -offset=2000000 192.168.1.1:wgt634u.bin.1
flash0.os; \
boot -elf flash0.os:'
This does not appear to have any ill effects on normal operation. If
there's a TFTP server listening when it boots, it flashes the image, in 2
pieces of 2 MB each to avoid errors.
If there's no TFTP server listening, it waits a few seconds, times out, and
then boots normally.
Is there any reason I shouldn't add this to the wiki? It helps to make the
wgt634u more like other devices in its TFTP-booting behavior.
Thanks,
Dan
