Build & Run instructions:
|
||||
|
||||
1) Install mkbootimg and dtbTool from
|
||||
git://codeaurora.org/quic/kernel/skales (15ece94f09 worked for me)
|
||||
2) Setup CROSS_COMPILE to aarch64 compiler
|
||||
3) make dragonboard410c_config
|
||||
4) make
|
||||
5) generate fake, empty ramdisk (can have 0 bytes)
|
||||
$ touch rd
|
||||
|
||||
6) Generate qualcomm device tree table with dtbTool [1]
|
||||
$ dtbTool -o dt.img arch/arm/dts
|
||||
|
||||
7) Generate Android boot image with mkbootimg [2]:
|
||||
$ mkbootimg --kernel=u-boot-dtb.bin --output=u-boot.img --dt=dt.img \
|
||||
--pagesize 2048 --base 0x80000000 --ramdisk=rd --cmdline=""
|
||||
|
||||
8) Enter fastboot (reboot board with vol- button pressed)
|
||||
|
||||
9) Boot it:
|
||||
$ fastboot boot u-boot.img
|
||||
or flash as kernel:
|
||||
$ fastboot flash boot u-boot.img
|
||||
$ fastboot reboot
|
||||
|
||||
|
||||
What is working:
|
||||
- UART
|
||||
- GPIO (SoC)
|
||||
- SD
|
||||
- eMMC
|
||||
- Reset
|
||||
- USB in EHCI mode (usb starts does switch device->host, usb stop does the opposite)
|
||||
- PMIC GPIOS (but not in generic subsystem)
|
||||
- PMIC "special" buttons (power, vol-)
|
||||
|
||||
What is not working / known bugs:
|
||||
- SDHCI is slow (~2.5MiB/s for SD and eMMC)
|
||||
|
||||
[1] To boot any kernel image, Little Kernel requires valid device tree for the
|
||||
platform it runs on. dtbTool creates device tree table that Little Kernel scans.
|
||||
Later on proper device tree is passed to next boot stage.
|
||||
Full device tree is not required to boot u-boot. Enough would be:
|
||||
/dts-v1/;
|
||||
|
||||
/ {
|
||||
model = "Qualcomm Technologies, Inc. Dragonboard 410c";
|
||||
compatible = "qcom,dragonboard", "qcom,apq8016-sbc";
|
||||
qcom,msm-id = <0xce 0x0 0xf8 0x0 0xf9 0x0 0xfa 0x0 0xf7 0x0>;
|
||||
qcom,board-id = <0x10018 0x0>;
|
||||
#address-cells = <0x2>;
|
||||
#size-cells = <0x2>;
|
||||

|
||||
|

memory {

|
||||
reg = <0 0x80000000 0 0x3da00000>;
|
||||
};
|
||||
};
|
||||
|
||||
but for simplicity (and because size of image is not that critical) we use
|
||||
existing Qualcomm device trees.
|
||||
|
||||
[2] Note that ramdisk is required, even if it is unused.

================================================================================
|
||||
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

||||
