[Bismark-devel] flashing woes - instructions don't seem to work

[Bismark-devel] flashing woes - instructions don't seem to work

[Nick Feamster]

Guys,

I think the instructions need some work.

First, I tried the "sysupgrade" with the appropriate binary.  That appeared to re-flash the router, but not otherwise do much.  After that upgrade, the router appeared on 192.168.42.1, but I could no longer ssh into it, and the normal Web interface did not work.

Then, I figured I would try Srikanth's flashing instructions.  First, it's not clear what the "reset" button is.  I figure that must be the factory reset button, as opposed to some button on the front of the box (I tried everything).  I did not get any of the flashing sequences that the instructions describe.  At this point, tftp fails, and I see very strange pings:

1:54am:kenmore-square:tmp% ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes

So, at this point, I am stuck.

Usually the only interface enabled after a reflash is telnet. Was telnet 
busted, too?

Otherwise you've found a bug. Up until now I've been reflashing with 
atftp exclusively on Linux.

I have revised the instructions here.

Hmm... what did you get? how long did you hold the button down for? (see 
above instructions)

This is normal, actually. You are pinging a very primitive network stack 
built into uboot(redboot?). The system time is set to the epoch. (1970 
or so)

It sounds like your tftp failed.

Still stuck?

We got it all working last night.

Important point not listed in the instructions: Waiting ~5-6 minutes is *key*.

Also, more (and more accurate) descriptions of the blinking lights will boost people's confidence that the "right thing" is happening.
