Re: [microblaze-uclinux] MicroBlaze uClinux, compiling on win32 and u-boot

[DeviPrasad Natesan <ndprasad@xxxxxxxxx>]

Hi,
Not sure whether this will help u. I am using the u-boot 1.1.13 as the
bootloader (since i like all their functionality particularly their
flash tool sets).  I have enabled booting uc-linux from jffs2
partition. (Ofcouse i got to add, copy few files/functions from other
architecture to make it work). This works very consistently in the
last few months.

When i started the worked in did face this problem. After setting the
compiler flags in the main makefile to whatever options enabled (like
barrell shifter, di etc) in the microblaze, the problem went away.

Also, i am not sure anyone maintains u-boot for microblaze.

regards
- Prasad
