UART - SD card - PSCI reset - Environment in EXT4 partition 1 in SD card (check defconfig for details) dont forget to insert the card in the SD slot before booting if you are going to make mods to the environment ================================================================================ Build & Run instructions ================================================================================ 1) Install mkbootimg and dtbTool from Codeaurora: git://codeaurora.org/quic/kernel/skales commit 8492547e404e969262d9070dee9bdd15668bb70f worked for me. 2) Setup CROSS_COMPILE to aarch64 compiler or if you use ccache just do CROSS_COMPILE="ccache aarch64-linux-gnu-" 3) cd to the u-boot tree $ make dragonboard820c_config $ make -j `nproc` 4) generate fake, empty ramdisk (can have 0 bytes) $ touch rd 5) Generate qualcomm device tree table with dtbTool $ dtbTool -o dt.img arch/arm/dts 6) Generate Android boot image with mkbootimg: $ mkbootimg --kernel=u-boot-dtb.bin \ --output=u-boot.img \ --dt=dt.img \ --pagesize 4096 \ --base 0x80000000 \ --ramdisk=rd \ --cmdline="" 7) Reboot the board into fastboot mode - plug the board micro-usb to your laptop usb host. - reboot the board with vol- button pressed 8) Boot the uboot image using fastboot $ fastboot boot u-boot.img or flash it to the UFS drive boot partition: $ fastboot flash boot u-boot.img $ fastboot reboot ================================================================================ To boot a linux kernel from SDHCI with the ROOTFS on an NFS share: ================================================================================ 1) create an EXT4 partition on the SD card (must be partition #1) 2) build the kernel image and dtb (documented extensively somewhere else) 3) copy the drivers to the NFS partition (ie: 192.168.1.2 /exports/db820c-rootfs) 4) add the u-boot headers to the image: $ mkimage -A arm64 \ -O linux \ -C none \ -T kernel \ -a 0x80080000 \ -e 0x80080000 \ -n Dragonboard820c \ -d $kernel/arch/arm64/boot/Image \ uImage 5) copy the generated uImage and the device tree binary to the SD card EXT4 partition $ cp uImage /mnt/boot/ $ cp apq8096-db820c.dtb /mnt/boot/ 6) on the SD card create /extlinux/extlinux.conf as follows: default nfs prompt 1 timeout 10 LABEL nfs MENU NFS entry LINUX /uImage FDT /apq8096-db820c.dtb APPEND root=/dev/nfs rw \ nfsroot=192.168.1.2:/exports/db829c-rootfs,v3,tcp \ rootwait \ ip=dhcp consoleblank=0 \ console=tty0 \ console=ttyMSM0,115200n8 \ earlyprintk earlycon=msm_serial_dm,0x75b0000 \ androidboot.bootdevice=624000.ufshc \ androidboot.verifiedbootstate=orange \ androidboot.ver0 7) remove the SD card from the laptop and insert it back to the db820 board. the SD card EXT4 partition#1 should contain: /uImage /apq8096-db820c.dtb /extlinux/extlinux.conf 8) reboot the db820 board ================================================================================ Successful boot sequence ================================================================================ Format: Log Type -
