opensbi

sudo apt install gcc-riscv64-linux-gnu

git clone https://github.com/riscv-software-src/opensbi.git

cd opensbi
make CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic FW_PIC=y -j$(nproc)
cd ..

uboot

sudo apt install bison swig flex libpython3.11-dev python3-setuptools

git clone https://github.com/smaeul/u-boot.git -b d1-wip

cd u-boot
make lichee_rv_dock_defconfig
# make menuconfig
make CROSS_COMPILE=riscv64-linux-gnu- OPENSBI=../opensbi/build/platform/generic/firmware/fw_dynamic.bin -j$(nproc)
cd ..

kernel 的设备树使用的是 uboot 传递的，如果要改这个设备树就要重新编译 uboot 并烧录。如果 sd 卡已经分区，烧录之前要执行sudo sgdisk /dev/sdc -o清除分区（不会破坏数据），再烧录 uboot。再重新执行一次分区命令分区就回来了，数据也可以访问

kernel linux

git clone https://github.com/smaeul/linux.git -b d1/all

# 手动添加 licheerv_defconfig：https://github.com/jamesgraves/licheerv-debian-linux/blob/main/licheerv_linux_defconfig
cd linux/
make ARCH=riscv licheerv_defconfig
# make ARCH=riscv menuconfig
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- KCFLAGS='-fno-asynchronous-unwind-tables -fno-unwind-tables' -j$(nproc)
cd ..

extlinux.conf

默认使用 uboot 的设备树

label default
	linux /Image
	append root=/dev/mmcblk0p2 rootwait console=ttyS0,115200 earlycon=sbi ignore_loglevel init=/lib/systemd/systemd

rootfs

sudo apt install mmdebstrap qemu-user-static
sudo mmdebstrap --architectures=riscv64 unstable rootfs "deb http://mirrors.tuna.tsinghua.edu.cn/debian unstable main"


sudo chroot ./rootfs
passwd

apt update
apt install network-manager # nmcli 连 wifi

exit

rootfs镜像

dd if=/dev/zero of=rootfs.img bs=1G count=1
sudo mkfs.ext4 rootfs.img
mkdir rootfs_mount
sudo mount rootfs.img rootfs_mount
sudo cp -rfp rootfs/* rootfs_mount
sudo umount rootfs_mount
rm -r rootfs_mount
sudo e2fsck -f rootfs.img
sudo resize2fs -M rootfs.img

烧录到sd卡

# 分区
sudo sgdisk /dev/sdc -o \
--new=1:4096:69631 --change-name=1:boot \
--new=2:69632: --change-name=2:rootfs \
-p
# 32MiB、剩余全部

# 格式化
sudo mkfs.vfat /dev/sdc1

# uboot
sudo dd if=./u-boot/u-boot-sunxi-with-spl.bin of=/dev/sdc seek=256
sync

# linux
sudo mount /dev/sdc1 /mnt
sudo mkdir /mnt/extlinux
sudo cp ./linux/arch/riscv/boot/Image /mnt/
sudo cp ./extlinux.conf /mnt/extlinux/
sync
sudo umount /mnt

# rootfs
sudo dd if=./rootfs.img of=/dev/sdc2 bs=4096
sync

恢复分区大小

# 如果 rootfs 分区被电脑自动挂载了需要先用 umount 卸载

sudo e2fsck -f /dev/sdc2
sudo resize2fs /dev/sdc2

安装模块

sudo mount /dev/sdc2 /mnt

cd linux
sudo make modules_install ARCH=riscv INSTALL_MOD_PATH=/mnt KERNELRELEASE=6.1.0-rc3+
# 6.1.0-rc3+ 来自于 uname -r，以实际为准

sudo rm /mnt/lib/modules/6.1.0-rc3+/build
sudo rm /mnt/lib/modules/6.1.0-rc3+/source

sudo umount /mnt
cd ..

wifi

git clone https://github.com/lwfinger/rtl8723ds.git

# 在 Makefile 里添加这行
KBUILD_CFLAGS += -fno-asynchronous-unwind-tables -fno-unwind-tables

cd rtl8723ds
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- KSRC=../linux modules -j$(nproc)
cd ..

sudo mount /dev/sdc2 /mnt

sudo cp ./rtl8723ds/8723ds.ko /mnt/lib/modules/6.1.0-rc3+/kernel/drivers/net/wireless/
sudo depmod -a -b /mnt 6.1.0-rc3+

sudo umount /mnt

其他

nmcli r wifi on # 打开 wifi
nmcli dev wifi # 扫描 wifi，按 q 退出页面
nmcli dev wifi connect "ChinaNet-45F7" password "12345678"

date -s '2024-04-26 19:07:00' # 设置为实际时间，如果系统时间和实际时间误差过大就访问不了 apt update
apt update

• 设置时区：ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
• apt https 支持：ca-certificates
• ntp 自动同步支持：chrony

问题

• kernel_comp_addr_r or kernel_comp_size is not provided!
  extlinux.conf 的 Image 不要 .gz
• mmc_load_image_raw_sector: mmc block read error
  使用sudo sgdisk /dev/sdc -o清除 sd 卡的分区信息，再重新烧录 uboot，再重新分区

设备树

在 uboot 里新加了个设备树，使用了 rgb800x480 7 寸屏，电阻触摸 ic 是 ns2009，tsc2007 驱动是兼容的，ti,x-plate-ohms 是 x 方向的电阻，一个通用值就行，用于判断按下抬起，其 gpios 是笔中断

linux 里要开启 lcd pwm，input event interface，tsc2007，i2c，图形方面可能要开启 drm？不太确定，摸索过程中开启了不少相关功能

uboot 里的 d1 设备树和 d1s 有交叉，有点乱，我直接把 linux 里的复制过来统一加了个new-的前缀，看起来方便，内容是一致的

u-boot/configs/lichee_rv_dock_defconfig 里的 CONFIG_DEFAULT_DEVICE_TREE 的值改成"new-sun20i-d1-lichee-rv-dock-ext"，u-boot/arch/riscv/dts/Makefile 里加dtb-$(CONFIG_TARGET_SUN20I_D1) += new-sun20i-d1-lichee-rv-dock-ext.dtb

桌面

已测试 xcfe4、lxde，使用 xfce4 时系统占用约 350MB 的内存，使用 lxde 时系统占用约 150MB 的内存。桌面比较卡，可能是没有使用 dma2d 的原因
