Hi Albert and Masahiro,
surprisingly I have tested zynq in Tom's repo and I am getting stuck in full u-boot. I have also tried SPL with MMC and it is hanging in the same location
U-Boot SPL 2014.07-rc2-00063-g3fe1a8545b55 (Jun 04 2014 - 11:57:12) mmc boot reading system.dtb spl_load_image_fat_os: error reading image system.dtb, err - -1 reading u-boot-dtb.img reading u-boot-dtb.img
U-Boot 2014.07-rc2-00063-g3fe1a8545b55 (Jun 04 2014 - 11:57:12)
I2C: ready Memory: ECC disabled DRAM: 1 GiB
Problem is with relocation and it is not related to OF_CONTROL.
I have added 3 pending patches on the top of current master next and "ARM: zynq: Enable generic board for Xilinx Zynq" fix the problem. That's why I think that is easier for just apply it to mainline repo because we need to apply this patch anyway.
Masahiro: Can you please check if the latest u-boot is working for you? Albert: If Masahiro confirms the same issue, can I send you one more pull request with these 3 fixes? (I have also run buildman on them too) (Enabling generic board, Fix message which is caused by enabling generic board,
- one fix from Masahiro regarding compilation out of tree files for SPL).
I found how to fix the problem.
Add one line to arch/arm/cpu/armv7/zynq/u-boot.lds as follows:
--- a/arch/arm/cpu/armv7/zynq/u-boot.lds +++ b/arch/arm/cpu/armv7/zynq/u-boot.lds @@ -18,6 +18,7 @@ SECTIONS .text : { *(.__image_copy_start)
*(.vectors) CPUDIR/start.o (.text*) *(.text*) }It worked on my ZC706 board.
Interesting that it is not needed for GENERIC_BOARD but anyway this fix is also works for me.
I think it is working with GENERIC_BOARD by coincidence.
"_start" symbol should be 0x04000000 (=CONFIG_SYS_TEXT_BASE) But it is set to 0 without fixing the linker script.
Masahiro: Can you please send proper patch which Albert or Tom can directly take? Link to origin commit sha will be also useful to point where the problem happened.
Please add this to the patch. Tested-by: Michal Simek monstr@monstr.eu
Done. http://patchwork.ozlabs.org/patch/356300/
Albert, This is a fatal bug. Please pick it up asap.
And please apply the followings as well: http://patchwork.ozlabs.org/patch/352484/ http://patchwork.ozlabs.org/patch/352672/ They also fix the bugs you added by commit 41623c91.
Best Regards Masahiro Yamada
