I am process of downloading the 2009q3 version from
codesourcery
Albert mentioned he is using it. Are you on the same
version as
well?
No, I'm using ELDk 4.2
[sp] Okay, so I downloaded both 2009-q3 and 2010.09-50
versions of the
Codesourcery Lite edition. There is no difference in the observations between
2009q3 and 2010q1.
[snip]...[snip]
There were some good patches posted recently esp the bss_debug tool and fix for ARM relocation from Andreas. Applied them in order to get more information.
In addition, added print indicating the function being called in for (init_funcptr= ....) loop within board_init_f().
Also added a print in the function omap3_evm_get_revision() just to see if it ever gets called in due to incorrect sequencing.
I could confirm that functions in init_sequence[] are called and omap3_evm_get_revision() is not called in this sequence.
When everything failed, I went back to the u-boot.lds and changed the way overlay is defined.
...AND PROBLEM SEEMS TO BE SOLVED!
I can now compile u-boot with both 2009q1 and 2010q1 without any error. (yet to try with 2010.09)
To verify, I wanted to do a before-and-after comparison but couldn't have done for the omap3_evm - used omap3_beagle instead.
I haven't yet tried running the binary on the board; but here are top level observations:
1) .bss and .rel.dyn are starting at same address. 2) The size of .rodata has increased. (Why? not yet spent time on?)
Sending the patch in next few mins:
