Problem updating Busybox from router (readonly filesystem)

[loicloicloicloic]

Hello everyone,

I am not sure if this is the right section for this question.

I have a Linksys WRT54G with the Tomato firmware on it.

So the system running on the router is Busybox 1.14., which as far as I know is Linux-based.

I want to update the busybox to the newest version, using ipkg which is the only package manager it has installed on it.

By the way, I use telnet to access the router.
So I use # ipkg install (the url to newest busybox release)

but at some point it stops and says:

mkdir: cannot create directory '//opt/usr/': Read-only file system

so what can I do? How can I make the filesystem read-write?

Can anyone help ? That would be really helpful!

Thanks a lot,

Loic

I haven't worked with this, but I suspect that you are going to need to copy the image to your computer system and run it in an emulator so you can install the new version of BusyBox, then move the image back to the router. I am just starting to get involved in embedded Linux development, so I can't say much more than this. I don't even know what processor is running the Linksys router (ARM?).
