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 }
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. 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.
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"
Means even uart node is not written in zynq-zed.dts serial configurations are static driver it self as of now.
Please check and may be you can try u-boot-dtb.elf.
thanks!
