ok if I go to the codesourcery web site and choose the following toolchain ARM uClinux and then choose cortex-m1 or cortex-m3 the versions within their tool chain (currently) are
GNU Binary utilities 2.19.51-sg++ GNU C & C++ Compilers 4.4.1-sg++ GNU Debugger 6.8.50-sg++ uClibc C Library 0.9.30-sg++ They use gcc 4.4.1 because it fully supports the latest and greatest ARMv7 cores (ie cortex). Will try to use buildroot / manual build with the versions above to and get a working tool chain going. --- On Tue, 11/24/09, steven taffs <steventa...@yahoo.com> wrote: > From: steven taffs <steventa...@yahoo.com> > Subject: Re: [uClinux-dev] ARM support > To: "uClinux development list" <uclinux-dev@uclinux.org> > Date: Tuesday, November 24, 2009, 9:52 AM > Hi > > thanks for the info, I will try and download the source > code from the codesourcery website so I can see which > version of gcc / bin / libc they are using and then > use your instructions in the text file to hopefully build a > new toolchain. > > I think its important to update the ARM toolchain as ARM > are moving to the newer cortex devices, and I for one would > like to see uClinux up and running on these new devices. > > I will email my progress. > > regards > > steve > > --- On Tue, 11/24/09, Greg Ungerer <g...@snapgear.com> > wrote: > > > From: Greg Ungerer <g...@snapgear.com> > > Subject: Re: [uClinux-dev] ARM support > > To: "uClinux development list" <uclinux-dev@uclinux.org> > > Date: Tuesday, November 24, 2009, 7:22 AM > > > > Hi Steven, > > > > steven taffs wrote: > > > arm-linux-tools-20070808 looks like it was built > with > > glibc-2.3.6 does that mean uClibc cant be selected / > used > > within uClinux make menuconfig when using this tool > chain ? > > > > The libc in the toolchain does't matter when compiling > the > > uClinux-dist. > > It is completely self contained. you can (and should) > > select uClibc when > > compiling for non-MMU targets.
