Topic: Custom toolchain on Chumby

Hi,

I wanted to ask if it is possible to install a custom toolchain, build with crosstool-ng, directly onto the c1. If it is possible, how can I do this? I know there is the falconwing toolchain but I need some things which don't build with this one.

By the way: Is it possible to expand the root partition? I have a 8gb microsd and it works with an expand storage but when I try to expand the root partition my c1 doesn't start anymore.

Thanks for help

Just run the "gcc" command and you'll get instructions on installing the local build tools from the Chumby servers. smile

I know. But than I get falconwing toolchain with gcc 4.3.3 or something like that. I need at least gcc 4.6 and therefor have build a custom toolchain. Know I don't know how to include it on my c1.

Re: Custom toolchain on Chumby

Can you use gcc 4.3.3 to build gcc 4.6?  It will take a while and you might need some swap for it to work.

I'd also look at cross-compiling with the Code Sourcery Lite tools - they're at http://www.mentor.com/embedded-software … e-edition/ and there are both Windows- and Linux-hosted versions.

I will try it. My main problem is, I tried to install scratchbox following the instructions on wiki page. But when I try to install C-libraries to target chumby I always get the error message: Failed to install C-library to target: Chumby.
Maybe anyone know how I can fix this? I tried the toolchain 2009q1 and 2008q3 from the wiki but ended up with this error with both of them.

Yeah, rewriting the C libraries with a newer version is something I'd only attempt with a good filesystem backup on a spare microSD card.  I've done things like it before, but you need to remount the root as read write and ideally use a statically-linked busybox so changing the library while you're running doesn't kill your own tools.
