6 What is working (enough to boot a distro from SD card)
7 ================================================================================
11 - Environment in EXT4 partition 1 in SD card (check defconfig for details)
12 dont forget to insert the card in the SD slot before booting if you
13 are going to make mods to the environment
15 ================================================================================
16 Build & Run instructions
17 ================================================================================
19 1) Install mkbootimg and dtbTool from Codeaurora:
21 git://codeaurora.org/quic/kernel/skales
22 commit 8492547e404e969262d9070dee9bdd15668bb70f worked for me.
24 2) Setup CROSS_COMPILE to aarch64 compiler or if you use ccache just do
25 CROSS_COMPILE="ccache aarch64-linux-gnu-"
27 3) cd to the u-boot tree
29 $ make dragonboard820c_config
32 4) generate fake, empty ramdisk (can have 0 bytes)
36 5) Generate qualcomm device tree table with dtbTool
38 $ dtbTool -o dt.img arch/arm/dts
40 6) Generate Android boot image with mkbootimg:
42 $ mkbootimg --kernel=u-boot-dtb.bin \
50 7) Reboot the board into fastboot mode
51 - plug the board micro-usb to your laptop usb host.
52 - reboot the board with vol- button pressed
54 8) Boot the uboot image using fastboot
56 $ fastboot boot u-boot.img
58 or flash it to the UFS drive boot partition:
60 $ fastboot flash boot u-boot.img
64 ================================================================================
65 To boot a linux kernel from SDHCI with the ROOTFS on an NFS share:
66 ================================================================================
68 1) create an EXT4 partition on the SD card (must be partition #1)
70 2) build the kernel image and dtb (documented extensively somewhere else)
72 3) copy the drivers to the NFS partition (ie: 192.168.1.2 /exports/db820c-rootfs)
74 4) add the u-boot headers to the image:
83 -d $kernel/arch/arm64/boot/Image \
86 5) copy the generated uImage and the device tree binary to the SD card EXT4
89 $ cp uImage /mnt/boot/
90 $ cp apq8096-db820c.dtb /mnt/boot/
92 6) on the SD card create /extlinux/extlinux.conf as follows:
101 FDT /apq8096-db820c.dtb
102 APPEND root=/dev/nfs rw \
103 nfsroot=192.168.1.2:/exports/db829c-rootfs,v3,tcp \
105 ip=dhcp consoleblank=0 \
107 console=ttyMSM0,115200n8 \
108 earlyprintk earlycon=msm_serial_dm,0x75b0000 \
109 androidboot.bootdevice=624000.ufshc \
110 androidboot.verifiedbootstate=orange \
113 7) remove the SD card from the laptop and insert it back to the db820 board.
114 the SD card EXT4 partition#1 should contain:
117 /extlinux/extlinux.conf
119 8) reboot the db820 board
