The primary source for Linux kernels for ColdFire targets is the set of LTIB distributions provided on the Freescale web site; the ColdFire changes have not yet been incorporated into the upstream Linux kernel sources. At the time this release was prepared, the kernel in the current LTIB distribution for MCF5445x was based on 2.6.23 kernel, while that for MCF547x/8x was based on 2.6.25. These are the minimal versions for the respective platforms.
This release of Sourcery G++ Lite for ColdFire GNU/Linux includes NPTL (Native POSIX Thread Library) support in the GNU C Library. Supporting NPTL requires that you apply an additional patch to the kernel sources and rebuild the kernel. This release of Sourcery G++ is not compatible with older or unpatched kernels, even if your applications do not use NPTL features.
You can find the required kernel patch and instructions for applying it in the Sourcery G++ Knowledge Base.
