Actually, looking into u-boot_2016.03 (this is this uboot version in morty by default right ?) it seems the zynq_zybo.h is different. http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/zynq_zybo.h;h=0882fe36bd82ef68b9515c0c265fc4015d673496;hb=df61a74e6845ec9bdcdd48d2aff5e9c2c6debeaa And the commit in poky for u-boot point to this revision df61a74e6845ec9bdcdd48d2aff5e9c2c6debeaa. So I need to upgrade the revision I guess. Maybe the best things to do is to upgrade my build from morty to pyro . It uses the new u-boot version 2017.01. I'll try it I think.

Ok I understand the flow. Bitstream is loaded before u-boot for sure. Since I'm using the u-boot from meta-xilinx, I should have the config options set correctly right ? The only things I have to do actually is to attach correctly a PS i2c to EMIO, then to pin N18 and N17 on zybo ? I will check this part tonigh ! >>>If you need FSBL then you will need meta-xilinx-tools, or you will need to >>>do it manually. >> Understood.

U-Boot can already read and setup the MAC from an I2C device, no need to deal with FSBL. The config to point at the I2C device is already configured by default for the Zybo. http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/zynq_zybo.h;h=808967cee331dd78380dc61e60f72c6643ea9e36;hb=HEAD#l17 The code that does the ethaddr setup. http://git.denx.de/?p=u-boot.git;a=blob;f=board/xilinx/zynq/board.c;h=90ef542458a9c7a19e64be1c031282fe5f5cf3f6;hb=HEAD#l119 > > So I'll have a fsbl.elf, but is there an easy way to add this .elf to > boot.bin set in meta-xilinx ? No, not in meta-xilinx. The bootgen tool which is required for FSBL images is only available from the Xilinx tools, and only meta-xilinx-tools integrates with them. > > What I understood from meta-xilinx is : we include the u-boot.elf through > SPL_BINARY into boot.bin ? How can I add also my fsbl.elf ? In meta-xilinx the generated boot.bin only contains U-Boot SPL (full U-Boot is loaded from the boot device from the u-boot.img file). > > > > I’ve also seen this topic : > https://lists.yoctoproject.org/pipermail/meta-xilinx/2017-April/002702.html > > But it seems it uses meta-xilinx-tools layer.
