We are working with the MPC8348E-MITX board.
The in-box LTIB is linux kernel 188.8.131.52.
we are attempting to upgrade to 2.6.22
Whats the point? Having encountered a PCI enumeration problem with a PLX 6152 bridge,
we are attempting to upgrade the kernel.
based on this thread in freescale forums, it looks like 2.6.22 upgrade has been done
before. not too extensively documented, but a good start. so I will add a bit of color here:
we completed changes to the ltib files
config/platform/mpc8349itx/main.lkc, created linux-2.6.22-mpc8349itx.config,
along with dist/lfs-5.1/kernel/kernel-2.6.22-mpc8349itx.spec.in
so far so good. after ltib --configure starts the 2.6.22 build,
it downloads the kernel from bitshrine
but in www.bitshrine.org/gpp
, no suitable
patch file exists for kernel-2.6.22-mpc8349itx
in fact the patches die off after 2.6.13 and 2.6.16
well, after booting linux 2.6.22 and loading the ramdisk, the system hangs :-o
now that we've come this far, we'd like to confirm that this upgrade is
feasible, and perhaps some advice on how to locate and incorporate patch file(s).
we are trying to figure out...
1. will this work ?
2. is there any way to know what patches exist in PPP?
3. assuming 2.6.22 can be built for the mpc8349e, what became of the earlier patches from 2.6.1x? Were they propagated upstream to kernel.org?
