system-upgrade.sh

[MarcelJ]

Hi,

I'm not using OpenWRT but something very similar based on buildroot. I included webif in my configuration and what I want to do is get the firmware upgrade to work using system-upgrade.sh.

Unfortunately my scripting isn't all that well and I have a tough time getting it to work properly, so I hope someone can explain so things to me and perhaps give some hints to get me going.

The system-upgrade.sh script seems to run fine. I can select my firmware and it uploads to my board and is placed in /tmp with some random name assigned.
Than, I notice that the read_var() is called and I can tell that the whole thing hangs at 'read LINE' in this function.

I suppose read LINE is either not functioning well or perhaps the input to it doesn't work properly. I just have no idea how to find the root cause.

Anyone have an idea how to make this work or what I could be missing ?

thanks,
Marcel

I ended up by skipping the read_var part and jump to do_upgrade immediately. It works fine for me but I still don't understand the problem of "real LINE".

At least I can upgrade now, so I'm happy with that.

Are you using busybox httpd and haserl? While most of busybox is compatible with normal gnu utilities we have run into a few things that work differently than you would expect.

Yes I'm using busybox httpd and haserl. It's working fine except for the read LINE issue so far.
What I noticed is that read works in ash, but expect a return to be entered. Not sure if that's the real reason why it keeps hanging in my case. I haven't tried it further and just skipped it.
