Re: [Ltib] Auto update?

[Chris Westervelt]

I know for a fact that it is software related because it happened last week and 
I have several sets of good hardware and I have segregated builds (separate 
LTIB directories) of the same platform with product specific mods. A simple 
clean won't fix the problem.  I literally have to distclean to fix it.  After 
that, I rebuild a perfect rootfs/kernel.  The question I guess is what's the 
difference between clean and distclean in terms of re-generation of object 
modules.  That leads to another question, are any of the generated binaries 
outside of the LTIB root level directory except for the toolchain?  I will try 
the trick you mentioned.  Perhaps I can diff out the cause.

Hi Chris,

Do you mean on your target?  if so it could be a hardware problem.  
Alternatively it means you're trying to access an illegal address 
(impossible address) rather than a legal address that has nothing mapped 
to it.

One idea to confirm this is to get a rootfs running properly and then 
duplicate it, e.g.:

$ sudo cp -a rootfs rootfs.good

And then carry on working.  When the errors start happening, try 
switching to the good snapshot to see if the error occurs (hardware) or 
whether it's related to rootfs changes.

Regards, Stuart
