Yeah, on zynq7, things were simpler with u-boot providing both the SPL (or first stage boot.bin file), and the proper u-boot loader for the kernel. Things were all nicely tied together. Now, one has to tie a few knots to get "burnable" products ready-made by yocto. Take a look at https://github.com/Xilinx/meta-xilinx-tools/blob/master/README.md Basically, I switched to meta-xilinx-tools. This wasn't pretty since I am bound to building everything in docker containers through gitlab-ci. I finally managed to get things working the way we need it to. It's not a pretty tool stack, the Xilinx SDK is pretty hacky (cmd line tools have dependencies to X11 and run a fake gui to execute commands), but the trail is pretty beaten by now and most of the kinks have been run over a number of times! ;) Basically, through IMAGE_CLASSES, xilinx-bootbin tasks are added to every images (which is being debated on meta-xilinx now, I submitted a patch where xilinx-bootbin becomes a proper recipe). Anyway, once you have the boot.bin, simply copying it to the first fat partition of SD (or eMMC) is good enough. I use a slightly modified version of http://git.yoctoproject.org/cgit.cgi/poky/tree/scripts/lib/wic/canned-wks/sdimage-bootpart.wks where I add more files to the boot partition: I made zynq-wic-sdcard.bbclass automatically inherited by all images through IMAGE_CLASSES with this content: WKS_FILES = "zynq-wic-sdcard.wks" IMAGE_DEPENDS_wic += "dosfstools-native mtools-native e2fsprogs-native" do_image_wic[depends] += "\ xilinx-bootbin:do_deploy \ " python () { initRdImage = d.getVar("INITRD_IMAGE", True) if initRdImage: d.appendVarFlag("do_image_wic", "depends", " " + initRdImage + ":do_image_complete") } IMAGE_CMD_wic_append() { cd ${DEPLOY_DIR_IMAGE} ln -sfv ${IMAGE_LINK_NAME}.wic.lz4 ${IMAGE_LINK_NAME}.sdcard.lz4 } =============================== And here's zynq-wic-sdcard.wks: # short-description: Create SD card image with a boot partition # long-description: Creates a partitioned SD card image. Boot files # are located in the first vfat partition. # !! the partition alignment must match that found in test files # we add 6MB to the boot partition to allow devs to copy a fpga.bin for example part /boot --source bootimg-partition --ondisk mmcblk --fstype=vfat --label ZBOOT --active --align 4096 --extra-space 6 part / --source rootfs --ondisk mmcblk --fstype=ext4 --label rootfs --align 4096 --extra-space 5 You can find my patch on meta-xilinx which turns xilinx-bootbin into a recipe (https://www.mail-archive.com/meta-xilinx@yoctoproject.org/msg01664.html). This is for the do_image_wic[depends] += "xilinx-bootbin:do_deploy" to work ;) Enjoy! -- _______________________________________________ meta-xilinx mailing list meta-xilinx@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-xilinx
