5================================================================================
6 What is working (enough to boot a distro from SD card)
7================================================================================
8 - UART
9 - SD card
10 - PSCI reset
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
14
15================================================================================
16 Build & Run instructions
17================================================================================
18
191) Install mkbootimg and dtbTool from Codeaurora:
20
21 git://codeaurora.org/quic/kernel/skales
22 commit 8492547e404e969262d9070dee9bdd15668bb70f worked for me.
23
242) Setup CROSS_COMPILE to aarch64 compiler or if you use ccache just do
25 CROSS_COMPILE="ccache aarch64-linux-gnu-"
26
273) cd to the u-boot tree
28
29 $ make dragonboard820c_config
30 $ make -j `nproc`
31
324) generate fake, empty ramdisk (can have 0 bytes)
33
34 $ touch rd
35
365) Generate qualcomm device tree table with dtbTool
37
38 $ dtbTool -o dt.img arch/arm/dts
39
406) Generate Android boot image with mkbootimg:
41
42 $ mkbootimg --kernel=u-boot-dtb.bin \
43 --output=u-boot.img \
44 --dt=dt.img \
45 --pagesize 4096 \
46 --base 0x80000000 \
47 --ramdisk=rd \
48 --cmdline=""
49
507) 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
53
548) Boot the uboot image using fastboot
55
56 $ fastboot boot u-boot.img
57
58 or flash it to the UFS drive boot partition:
59
60 $ fastboot flash boot u-boot.img
61 $ fastboot reboot
62
63
64================================================================================
65 To boot a linux kernel from SDHCI with the ROOTFS on an NFS share:
66================================================================================
67
681) create an EXT4 partition on the SD card (must be partition #1)
69
702) build the kernel image and dtb (documented extensively somewhere else)
71
723) copy the drivers to the NFS partition (ie: 192.168.1.2 /exports/db820c-rootfs)
73
744) add the u-boot headers to the image:
75
76 $ mkimage -A arm64 \
77 -O linux \
78 -C none \
79 -T kernel \
80 -a 0x80080000 \
81 -e 0x80080000 \
82 -n Dragonboard820c \
83 -d $kernel/arch/arm64/boot/Image \
84 uImage
85
865) copy the generated uImage and the device tree binary to the SD card EXT4
87 partition
88
89 $ cp uImage /mnt/boot/
90 $ cp apq8096-db820c.dtb /mnt/boot/
91
926) on the SD card create /extlinux/extlinux.conf as follows:
93
94 default nfs
95 prompt 1
96 timeout 10
97
98 LABEL nfs
99 MENU NFS entry
100 LINUX /uImage
101 FDT /apq8096-db820c.dtb
102 APPEND root=/dev/nfs rw \
103 nfsroot=192.168.1.2:/exports/db829c-rootfs,v3,tcp \
104 rootwait \
105 ip=dhcp consoleblank=0 \
106 console=tty0 \
107 console=ttyMSM0,115200n8 \
108 earlyprintk earlycon=msm_serial_dm,0x75b0000 \
109 androidboot.bootdevice=624000.ufshc \
110 androidboot.verifiedbootstate=orange \
111 androidboot.ver0
112
1137) remove the SD card from the laptop and insert it back to the db820 board.
114 the SD card EXT4 partition#1 should contain:
115 /uImage
116 /apq8096-db820c.dtb
117 /extlinux/extlinux.conf
118
1198) reboot the db820 board
120
