Biff, I see your point, and I was thinking about this before I started to patch the makefiles.
Of course, one would prefer the rootfs location as a configurable option for any target, but that involves too many changes: -- Kernel's CMDLINE is now hardcoded in the target-specific files -- Building the flash image is too platform-specific. For Edimax routers, you need to add the header, for other platforms you might not need it, or do something else. Also The Edimax makefiles always assume there's always a JFFS or Squashfs partition, while in my case there should be none. so, with these considerations, a separate profile for a Edimax-like router with USB rootfs is the thing that could be done with little blood (still, I require few updates in the core makefiles). It actually should run with BR-6204Wg: you just add the modules required for the wireless interface. regards, stan ----- Original Message ---- > From: bifferos <[EMAIL PROTECTED]> > To: OpenWrt Development List <openwrt-devel@lists.openwrt.org> > Sent: Wednesday, October 29, 2008 2:21:04 PM > Subject: Re: [OpenWrt-Devel] [PATCH] Edimax BR6104KP profile with rootfs on a > USB drive > > > Stanislav, > > I don't wish to belittle your efforts, and I think this will be > genuinely useful to quite a few people, however it's worth noting > that BR6104KP is not the only target that could benefit from > USB-root, therefore, one can see a series of profiles springing up alongside > every single target capable of USB (why not 4MB devices as well?).
