|
+Pre-built u-boot and kernels are available at https://xff.cz/kernels/
|
||
|
|
+
|
||
|
|
+You may need some firmware files for some part of the functionality. Those are
|
||
|
|
+available at: https://megous.com/git/linux-firmware
|
||
|
|
+
|
||
|
|
+If you want to reproduce my pre-built kernels exactly, you'll need to uncomment
|
||
|
|
+CONFIG_EXTRA_FIRMWARE_DIR and CONFIG_EXTRA_FIRMWARE in the defconfigs, and
|
||
|
|
+point CONFIG_EXTRA_FIRMWARE_DIR to a directory on your computer where the
|
||
|
|
+clone of https://megous.com/git/linux-firmware resides.
|
||
|
|
+
|
||
|
|
+You can also leave those two config options commented out, and copy the contents
|
||
|
|
+of https://megous.com/git/linux-firmware to /lib/firmware/ on the target device.
|
||
|
|
+
|
||
|
|
+You can use this kernel to run a desktop environment on Orange Pi SBCs,
|
||
|
|
+Arch Linux on your Pinephone, or to have a completely opensource OS on
|
||
|
|
+a Pocketbook e-ink book reader.

+Build instructions
|
||
|
|
+------------------
|
||
|
|
+
|
||
|
|
+These are rudimentary instructions and you need to understand what you're doing.
|
||
|
|
+These are just core steps required to build the ATF/u-boot/kernel. Downloading,
|
||
|
|
+verifying, renaming to correct directories is not described or mentioned. You
|
||
|
|
+should be able to infer missing necessary steps yourself for your particular needs.
|
||
|
|
+
|
||
|
|
+Get necessary toolchains from:
|
||
|
|
+
|
||
|
|
+- https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/ for 64bit Orange Pi PC2 and Orange Pi 3, PinePhone
|
||
|
|
+- https://releases.linaro.org/components/toolchain/binaries/latest/arm-linux-gnueabihf/ for 32bit Orange Pis, Pocketbook, TBS tablet
|
||
|
|
+
|
||
|
|
+Extract toolchains and prepare the environment:
|
||
|
|
+
|
||
|
|
+ CWD=`pwd`
|
||
|
|
+ OUT=$CWD/builds
|
||
|
|
+ SRC=$CWD/u-boot
|
||
|
|
+ export PATH="$PATH:$CWD/Toolchains/arm/bin:$CWD/Toolchains/aarch64/bin"
|
||
|
|
+
|
||
|
|
+For Orange Pi PC2, Orange Pi 3 or PinePhone:
|
||
|
|
+
|
||
|
|
+ export CROSS_COMPILE=aarch64-linux-gnu-
|
||
|
|
+ export KBUILD_OUTPUT=$OUT/.tmp/uboot-pc2
|
||
|
|
+ rm -rf "$KBUILD_OUTPUT"
|
||
|
|
+ mkdir -p $KBUILD_OUTPUT $OUT/pc2
|
||
|
|
+
|
||
|
|
+Get and build ATF from https://github.com/ARM-software/arm-trusted-firmware:
|
||
|
|
+
|
||
|
|
+ make -C "$CWD/arm-trusted-firmware" PLAT=sun50i_a64 DEBUG=1 bl31
|
||
|
|
+ cp "$CWD/arm-trusted-firmware/build/sun50i_a64/debug/bl31.bin" "$KBUILD_OUTPUT"
|
||
|
|
+
|
||
|
|
+Use sun50i_a64 for Orange Pi PC2 or PinePhone and sun50i_h6 for Orange Pi 3.
|
||
|
|
+
|
||
|
|
+Build u-boot from https://megous.com/git/u-boot/ (opi-v2020.04 branch) with appropriate
|
||
|
|
+defconfig (orangepi_one_defconfig, orangepi_pc2_defconfig, orangepi_pc_defconfig, orangepi_3_defconfig, tbs_a711_defconfig, pinephone_defconfig).
|
||
|
|
+
|
||
|
|
+My u-boot branch already has all the necessary patches integrated and is configured for quick u-boot/kernel startup.
|
||
|
|
+
|
||
|
|
+ make -C u-boot orangepi_pc2_defconfig
|
||
|
|
+ make -C u-boot -j5
|
||
|
|
+
|
||
|
|
+ cp $KBUILD_OUTPUT/.config $OUT/pc2/uboot.config
|
||
|
|
+ cat $KBUILD_OUTPUT/{spl/sunxi-spl.bin,u-boot.itb} > $OUT/pc2/uboot.bin
|
||
|
|
+
|
||
|
|
+Get kernel from this repository and checkout the latest orange-pi-5.18 branch.
|
||
|
|
+
|
||
|
|
+Build the kernel for 64-bit boards:
|
||
|
|
+
|
||
|
|
+ export ARCH=arm64
|
||
|
|
+ export CROSS_COMPILE=aarch64-linux-gnu-

|
+ export KBUILD_OUTPUT=$OUT/.tmp/linux-arm64
|
||
|
|
+ mkdir -p $KBUILD_OUTPUT $OUT/pc2
|
||
|
|
+
|
||
|
|
+ make -C linux orangepi_defconfig
|
||
|
|
+ # or make -C linux pocketbook_touch_lux_3_defconfig

||
|
|
+ # or make -C linux tbs_a711_defconfig
|
||
|
|
+ make -C linux -j5 clean

|
||
|

+ cp -f $KBUILD_OUTPUT/arch/arm64/boot/dts/allwinner/sun50i-h5-orangepi-pc2.dtb $OUT/pc2/board.dtb
|
||
|
|
+
|
||
|
|
+Build the kernel for 32-bit boards:
|
||
|
|
+
|
||
|
|
+ export ARCH=arm
|
||
|
|
+ export CROSS_COMPILE=arm-linux-gnueabihf-

+ make orangepi_defconfig
|
||
|
|
+ # or make pinephone_defconfig
|

|
|
+ make -C linux orangepi_defconfig
|
||
|
|

|
|
+ make -C linux -j5 zImage dtbs
|

|
|
+ cp -f $KBUILD_OUTPUT/arch/arm/boot/zImage $OUT/pc/
|

|
|
+ cp -f $KBUILD_OUTPUT/.config $OUT/pc/linux.config
|
||
|
|
+ cp -f $KBUILD_OUTPUT/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dtb $OUT/pc/board.dtb
|
||
|
|
+ # Or use sun8i-h3-orangepi-one.dtb for Orange Pi One
|

|

|

|
||
|
|
+PinePhone
|
||
|
|
+---------
|
||
|
|
+
|
||
|
|
+I don't run u-boot on PinePhone, so my pre-built kernel packages don't come
|
||
|
|
+with u-boot built for PinePhone.
|
||
|
|
+
|
||
|
|
+
|
||
|
|
+Kernel lockup issues
|
||
|
|
+--------------------
|
||
|
|
+
|
||
|
|
+*If you're getting lockups on boot or later during thermal regulation,
|
||
|
|
+you're missing an u-boot patch.*
|
||
|
|
+
|
||
|
|
+This patch is necessary to run this kernel!
|
||
|
|
+
|
||
|
|
+These lockups are caused by improper NKMP clock factors selection
|
||
|
|
+in u-boot for PLL_CPUX. (M divider should not be used. P divider
|
||
|
|
+should be used only for frequencies below 240MHz.)
|
||
|
|
+
|
||
|
|
+This patch for u-boot fixes it:
|
||
|
|
+
|
||
|
|
+ 0001-sunxi-h3-Fix-PLL1-setup-to-never-use-dividers.patch
|
||
|
|
+
|
||
|
|
+Kernel side is already fixed in this kernel tree.
