Three comments at least: 1. I personally would agree with the change to int, but since Wolfgang considers it a workaround to the linker issue, I won't accept it either. 2. IIRC, the linker emits a warning, not an error. We can live some time with a warning if it is documented and it is being worked on. 3. I did offer to try and find a minimal test case (one .c file, one .lds file, one simple command line) to cause the warning and submit it to the binutils list, but haven't had time so far. > Thanks > > Dirk Amicalement,

With 2009q1-203 it's an error and 'omap3_evm' isn't built: arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e33f] overlaps section .rel.dyn [8003f5e0 -> 80044e6f] arm-none-linux-gnueabi-ld: section .dynsym [80044e70 -> 80044f0f] overlaps section .bss [8003f5e0 -> 8007e33f] arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections make: *** [u-boot] Error 1 size: './u-boot': No such file Thanks Dirk > 3.

If you do a ./MAKEALL omap3_evm, yes, the build will fail. But (with 2010q1 at least, but I d'wager this works with 2009q3 as well) a 'make distclean; make omap3_evm_config; make' builds despite the linker message. Can you try this as a diagnostic measure? Also, you may want to try adding --no-check-sections to the linker flags -- again as a diagnostic measure only, not as a fix -- because a quick test shows me that the .bin is really different then. Amicalement,

I did a readelf analysis for 3 test cases (with 2009q1-203): 1) As reference, I built 'omap3_beagle' assuming that this is somehow the ELF file layout we want. Result [1]. 2) Build 'omap3_evm' with the 'convert omap3_evm_version to int patch' from http://lists.denx.de/pipermail/u-boot/2010-December/083524.html applied. Result [2]. 3) Build 'omap3_evm' without any code patches, but with the additional linker option --no-check-sections. Result [3]. Looking at (1) and (2) both built fine and the resulting ELF files have 2 program headers. In contrast to this, the resulting ELF file for (3) looks totally different with 3 program headers, an additional one just for .dynsym. So (3) looks really like a tool chain issue to me. By whatever reason using 'omap3_evm_version' as a u8 somehow breaks the linking with some tool chains. Or at least outputs a warning and creates an ELF file with totally different section headers. Comparing the resulting ELF file from 'omap3_beagle' (1) to the version with the int (2) it seems to me that this is what we want. So I'd like to re-send the int conversion patch from http://lists.denx.de/pipermail/u-boot/2010-December/083524.html in a proper format again as a workaround for this issue. Ok?

I think Wolfgang does not want this fix if it is a workaround to a bug, although it is not clear to me if this includes toolchain bugs.

Dear Albert ARIBAUD, In message <4D0794CF.5090608@free.fr> you wrote: > > I think Wolfgang does not want this fix if it is a workaround to a bug, > although it is not clear to me if this includes toolchain bugs. In any > case, the decision will be Wolfgang's, so it's best if he's Cc:ed just > in case. I'm perfectly willing to accept workarounds for bugs. But before fixing or working around some suspected bug we should first _understand_ what is happening. And here this is not the case. We do not understand yet what is going wrong, or why. We don;t even know if it's really depending on some too chain configuration or version. The risk is that we apply this patch now, and the problem which has not been actually fixed will bit us somewhere else again later. Please let's try understanding what goes wrong, and who is to blame for it. Best regards, Wolfgang Denk

When I'm using gcc 4.3.5 it is reached. In both cases I've used the same version of binutils, 2.20.1.

Sorry for going into this thread, but I've heard such a "fine" something like a dozens time before. And the beagleboard and the EVM are using the same start.S, so I thought I throw something into this thread about problems across tool chain versions. Even when it isn't about linker errors. I will be silent again. Regards, Alexander
