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.
[sp] Yes. This is what I wanted to confirm to ensure that relocation isn't breaking after the changes. In a way it was my testcase to see that I get similar map for omap3_beagle before and after making changes.
- 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.
[sp] No. I am not removing relocation. Do look at the patch. I just sent from my Linux box..
