Re: [microblaze-uclinux] uClinux bootup problems

[Rod Campbell <rod@xxxxxxxxxxxxxxxxxx>]

Thanks for your suggestion Holger - this was it.  After re-building
using the 20040315 version of the tools I got a good kernel bootup.  The
only other change I made was to turn off C_USE_BARREL, C_USE_DIV and
C_USE_MSR_INSTR.  Possibly only the last of these needs to be turned off
- the 20040315 tools do not appear to support the MSRSET opcode.      

My first guess it that the problem has to do with the flat file
utilities, since the kernel always got to the point where the root file
system was accessed (trying to load and run init).  Sometimes it went
further, but never fully booted.
