+Documentation for DragonBoard 410c is now located at:
+ doc/board/qualcomm/dragonboard410c.rst
-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>;
- chosen { };
- aliases { };
-
- memory {
- device_type = "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.
+Note that the installation method has changed: U-Boot is now installed into the
+"aboot" partition (replacing Little Kernel/LK). It is no longer packaged into
+an Android boot image and loaded through Qualcomm's LK bootloader.
