True, but not entirely. ELDK-3.1.1 has a glibc compiled with support of a certain version of the kernel (I guess it's 2.4.xx), so newer kernels might run (because they are obviously backwards compatible), but some features of 2.6 cannot be used (e.g. support for the latest syscalls, different HZ, etc...) A second issue is the boot procedure. If you are a beginner with linux, you'd probably start booting from NFS root as it gets installed in the ELDK/ppc_xxx directory. That probably won't work very well with latest 2.6 kernels (device files missing, sysfs not mounted, shmfs has different name, etc...) A third issue is the compiler issue. Some newer kernels might not compile correctly anymore with older compilers. These three things are what I meant with "supported" or "not supported". > The ELDK is primarily a *toolkit* which works with arbitrary C and > C++ programs and with any version of the kernel tree (at least in > theory; very recent version s of the Linux kernel [ > 2.6.14] cannot > be compiled with ELDK 3.1.x any more, but this is a different issue). See what I mean?

Ok, let's talk about "recommended" kernel then. I would never recommend someone unexperienced to start with a combination of ELDK-3.1.1 and kernel 2.6.xx. > > The one that comes with that version of ELDK? Just a guess ;-) > > Wrong guess. But it'd still be the one with most chances of success unless there are known problems with that kernel on a Sandpoint board. Greetings, -- David Jander Protonic Holland.
