Hi,
the Arndale board does not work anymore with current master HEAD.
If I turn on the board, I see exactly nothing.
I bisected it down to:
47ed5dd031d7d2c587e6afd386e79ccec1a1b7f7 is the first bad commit

arm: keep all sections in ELF file
That patch looks like Chinese to me, does one of you have an
idea what's
wrong here?
Are we missing a section, maybe for the SPL build?
So on Arndale, what file do you boot exactly? It sounds like not
u-boot.img but some tool stripping / modifying u-boot (or
spl/u-boot-spl) and having relied on certain sections being
stripped out
before being run.
Good point. Indeed I boot u-boot-dtb.bin (the SPL is
spl/arndale-spl.bin). So the Makefile does:
cat u-boot.bin u-boot.dtb >u-boot-dtb.bin
I guess the address under which U-boot expects to find the
attached dtb
changes due to the non-discarding.
Does any of the Arndale people have an idea how to fix this?
That's a little confusing as we use objcopy -O binary to make
u-boot.bin/u-boot-spl.bin and that would, I would think, drop these
sections anyhow. But some checking of binary size with the patch in
question locally reverted would help shed some light here.
So I did objdump -h on ./u-boot, the diff (sorted by the section name,
as the order of the section differed, and the size) is:
.ARM.attributes 0000002d
-.bss 00048b10
+.bss 00048b08
.bss_end 00000000

- works, + is broken.
+ is HEAD as of yesterday, - is the same with the patch in question
reverted. So the patch _adds_ some sections to the file.
u-boot-spl is exactly the same, for u-boot-spl.bin the broken version
ends earlier (but until then is identical). arndale-spl.bin (which I
flash) is different, though.
Arndale uses CONFIG_OF_SEPARATE, and .text stays the same AFAICS.
I can do some more debugging tomorrow, am grateful for any hints.
Sorry for chiming in late. Did you try this?
http://patchwork.ozlabs.org/patch/300928/
I cannot reach the server. Can you give me a hint what this patch is
about (or a Subject: line to search for on the ML?)
OK, now the server works again. Looks like this could fix it on the
first glance, but I momentarily cannot test this. Will try to do this ASAP.
Thanks,
André.
