When everything failed, I went back to the u-boot.lds and changed the way overlay is defined.
...AND PROBLEM SEEMS TO BE SOLVED!
This most probably means some of the code running before relocation uses BSS; see below.
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:
- .bss and .rel.dyn are starting at same address.
This is normal and should not have any negative impact as long as code that runs before relocation does not access BSS -- and it should not, since BSS only exists after relocation.
- The size of .rodata has increased. (Why? not yet spent time on?)
Weird. Can you provide all necessary info for duplicating these two builds?
Sending the patch in next few mins:
If that's a patch to remove the overlay in the .lds, it's a Nak from me already.
