Hi
As i have seen that the Xilinx support has entered master i just tried to boot it on a Xilinx Zynx Zedboard Rev. D. The build works with the xilinx git tree so i am pretty confident that its not some issues with bootgen or the embedded fpga image.
The board loads the fpga which can be seen by the blue "done" led of the ZedBoard. But then the LED turns off and about after a second or so it just lights up shortly again to turn off again. So it seems as if the board is somehow caught in a reboot loop. Any ideas what might be wrong?
I am building with: export PATH=~/xilinx/SDK/2013.3/gnu/arm/lin/bin:$PATH export CROSS_COMPILE=arm-xilinx-linux-gnueabi- make clean make distclean make zynq_zed_config make
The BOOT.BIN is build xilinx/SDK/2013.3/bin/lin64/bootgen -image u-boot.bif -w on -o BOOT.BIN
And u-boot.bif looks like that: the_ROM_image: {
[bootloader]zynq_fsbl_0.elf
system.bit u-boot.elf
I have added the zynq-zed.dtb file here, as i was not sure where else to put it...
I have just tested on zedboard rev-C I have here

And you should see something like this on your console

mainline u-boot support is using configuration based on dts files (OF_CONTROL) And because our DTSes are almost empty in mainline I expect you are not able to see anything from u-boot. I recommend you to copy dts file from xilinx kernel and then use u-boot-dtb version.
Ok i tried this, and now the reboot loops seems to be gone. The blue "done" led now only switches "on" one time and stays on. Unfortunatly i still don't see anything on the console in this case. I can see that the registers lr 0x1d70 0x1d70 pc 0xcf6c 0xcf6c But according to the u-boot map there is nothing and i am not sure how to get information about the relocation without u-boot command line.
Or the second option is to remove OF_CONTROL from zynq-common.h file and then I hope you should be able to see something on console.
Removeing OF_CONTROL gives a compile error: xilinx/zynq/u-boot-xlnx/arch/arm/lib/board.c:633: undefined reference to `checkboard' lib/built-in.o: In function `rsa_verify_with_keynode': xilinx/zynq/u-boot-xlnx/lib/rsa/rsa-verify.c:284: undefined reference to `fdtdec_get_int'
More things has changed recently. If you do these changes then non DT configuration is performed.

Then you can use u-boot also for boot.bin (bootgen) generation.
load fsbl as above and then dow u-boot run exit
If you use ML, as Michal said - u-boot operates through FDT support. But I guess even if you use u-boot.elf with FDT enabled, you must get the below error ** CONFIG_OF_CONTROL defined but no FDT - please see doc/README.fdt-control"
Mh, i now appended the fdt in the bif file. Is this the right approach?
I won't work.
Means even uart node is not written in zynq-zed.dts serial configurations are static driver it self as of now.
Does this mean that the serial drivers are statically defined and do not take the device tree file into account?
Jagan wasn't correct on this one because one of my patch series has changed this. For static configuration (without OF_CONTROL) are driver statically defined. For DT configuration is console selection taken from DTS/DTB.
Yes - I haven't check OF_ support is pushed on master as well.
Please check and may be you can try u-boot-dtb.elf.
Mh, don't know how to create this kind of file?
Jagan maybe knows more but I don't think u-boot-dtb.elf is generated. Just u-boot-dtb.bin is generated which should be copied as data file in xmd and not sure if binary file can be directly used for bootgen.
IMHO, there is a file u-boot-dtb (elf) generated when we build FDT u-boot I thought that can have a facility boot using BOOT.BIN.
I guess it's good to have a try.
thanks!
