| What is working (enough to boot a distro from SD card) |
| ================================================================================ |
| - 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 |
| |
