Yes, a few. * The static microwindows libraries were stripped and are useless for linking; updated RPM's are available. * The index for the local RTC has changed in the NTPD source so you may need to adapt your /etc/ntp.conf file; documentation was updated at http://www.denx.de/twiki/bin/view/DULG/UseNTPToSynchronizeSystemTimeAgainstRTC > I could see that the ELDK distro is well packed with all toolchains, > kernel and applications. > I could no find out the "target filesystem" ? If you install for example the "ppc_8xx" packages to the default location /opt/eldk, then /opt/eldk/ppc_8xx/ will be the root directory of your target filesystem. You can use this and export it on a NFS server; see the detailed documentation in the DULG. > Should the target filesystem be created manually from the directory > into which I install all the application RPMs.?

If you're talking about a standlone target filesystem you can use the SELF package; eitehr by using the SELF source RPM and modifying the build script, or by using the pre-build images in /opt/eldk/ppc_8xx/images/ and modifying those as documented, see http://www.denx.de/twiki/bin/view/DULG/HowToAddFiles and http://www.denx.de/twiki/bin/view/DULG/HowToIncreaseSizeOfRamdisk Or you can start from scratch using the standard tools like genext2fs, mkcramfs, mkfs.jffs2, etc. > How is the kernel and rotofs attachment done ? We normally use U-Boot to boot LInux. Just read the DULG for details: http://www.denx.de/twiki/bin/view/DULG/Manual > Do I need o do it with my bootloader passing command line arguments to > the kernel ? (I plan to use u-boot).

As I wrote: it's the tiny caches. Performance on RISC processors like the PowerPC stands and falls witch cache size. A PowerPC processor with only 2 kB Instruction Cache and 1 kB Data Cache like the MPC850 performs as castrated.
