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 .bss_start 00000000 .comment 0000001c @@ -14,8 +14,12 @@ .debug_loc 00045a4e .debug_ranges 00006f70 .debug_str 000123b4 +.dynamic 00000080 +.dynstr 0000001d +.dynsym 00000060 .got.plt 0000000c .hash 0000002c +.interp 00000011 .rel.dyn 00006fd8 .rodata 0000ae47 .text 0002cdf0
- 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?
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?)
Thanks, Andre.
