@spring 建议就16 或者 18 使用吧 高版本很多坑要填。。。

回复: 设备上面的有线网卡无法使用
正确答案:
试试:
ifconfig br-lan 你的IP
route add default gw 你的网关
或者
udhcpc -i br-lan

基于全志H5搭建主线开发环境
搭建A53调试环境
本文介绍如何A53的调试环境,调试最新的内核。
本实验调试基于全志H5芯片,使用nanopi-neo2开发板。
编译ATF
直接使用官方仓库,使用最新的ATF2.6代码。注意编译器百度自行安装, aarch64-linux-gnu- 推荐工具链使用最新的,下不赘述。
仓库:https://github.com/ARM-software/arm-trusted-firmware.git
make PLAT=sun50i_a64 DEBUG=1 bl31 CROSS_COMPILE=aarch64- linux-gnu-
编译完成后,将绝对路径导出,编译u-boot的时候需要使用。
export BL31=/path/to/bl31.bin
编译CRUST(全志协处理器的固件代码)
H5里面有一个openrisc 架构的协处理器,编译该代码,还需要安装改架构的交叉编译工具。
仓库地址:https://github.com/crust-firmware/crust
交叉编译工具下载地址:https://openrisc.io/software
make pine64_plus_defconfig && make -j5 scp CROSS_COMPILE=or1k-linux-musl-
export SCP=/src/crust/build/scp/scp.bin
编译u-boot:
u-boot 代码,我选择的是:u-boot-2021.10.tar.bz2 官方下载。
注意在编译U-BOOT前,请将ATF 和 CRUST的成果,路径导出。
ARCH=arm64 CROSS_COMPILE=aarch64 -linux-gnu- make nanopi_neo2_defconfig
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j16
烧录u-boot到SD卡:
U盘接入linux主机,dd进去。
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdx bs=8k seek=1编译文件系统:
我使用buildroot 搭建文件系统。版本:buildroot-2021.08.2.tar.gz
主要将以下配置选对。
选择生成CPIO镜像, 这样子跑RAMFS 调试比较方便。
编译后 将rootfs.cpio.gz 复制到你的 kernel/usr目录下。
编译内核:
内核源码:https://www.kernel.org/
下载自己感兴趣的版本。
make ARCH=arm64 CROSS_COMPILE=aarch64 -linux-gnu- defconfig
修改内核配置:
make ARCH=arm64 CROSS_COMPILE=aarch64 -linux-gnu- menuconfig- 支持ramfs
- 打开网络驱动
开始编译内核
make ARCH=arm64 CROSS_COMPILE=aarch64 -linux-gnu- Image -j16
make ARCH=arm64 CROSS_COMPILE=aarch64 -linux-gnu- dtbs -j16tftp启动内核:
setenv ipaddr 192.168.31.222
setenv serverip 192.168.31.3
tftp 0x40080000 Image
tftp 0x4FA00000 sun50i-h5-nanopi-neo2.dtb
booti 0x40080000 - 0x4FA00000到此,A53的开发环境搭建完毕。

【DIY教程】用D1实现提醒器
人体红外传感器坏了,那便手动设置GPIO吧,原理一样,硬件换上去就好了。
先看看效果图(没有UI)。。。
程序的大概组成:BOA实现web服务器,实现对提醒内容的配置。
LVGL程序实现UI,实现逻辑,蜂鸣器的,红外传感器的控制与读取。内核增加NFS支持
为了调试程序方便,打开NFS功能,方便板卡和服务器交换文件。
在
tina-d1-open/device/config/chips/d1/configs/nezha/linux-5.4
目录中,备份原始配置。cp config-5.4 config-5.4.bk
在
tina-d1-open/out/d1-nezha/compile_dir/target/linux-d1-nezha/linux-5.4.61
目录下make ARCH=riscv menuconfig #把如下选项打开 File systems ---> [*] Network File Systems ---> <*> NFS client support [*] NFS client support for NFS version 3 [*] NFS client support for the NFSv3 ACL protocol extension [*] NFS client support for NFS version 4 (EXPERIMENTAL) [*] NFS client support for NFSv4.1 (DEVELOPER ONLY)
修改完成后,将该目录下的
.config
复制为tina-d1-open/device/config/chips/d1/configs/nezha/linux-5.4/config-5.4
mboot;mkernel #重新编译uboot以及内核 make -j4 pack
增加NTP--网络对时
在tina-d1-open下执行如下:
source build/envsetup.sh lunch d1_nezha-tina make menuconfig
使用
/
可以在目录中进行查找,找到ntpd,打开后保存退出。make -j4 pack
LVGL支持
采用坛友的工程,在这个工程上进行修改。
链接:https://bbs.aw-ol.com/topic/303/哪吒d1开发板-lvgl7-源码下载-带git仓库/4
网页服务器
采用BOA作为网页服务器。
下载 boa-0.94.13.tar.gz
解压后进入src目录执行:
./configure --prefix=../../riscv-boa/ --host=riscv-linux
修改生成的Makefile
CC = riscv64-unknown-linux-gnu-gcc CPP = riscv64-unknown-linux-gnu-gcc -E
修改源码:
vi compat.h +120
#define TIMEZONE_OFFSET(foo) foo##->tm_gmtoff
编译后,生成的boa,复制到D1的/bin目录下,在D1根目录下新建
/WWW (这个目录下,放index.html)
/www/cgi-bin (这个目录下放运行cgi的bin文件)
/etc/boa/boa.conf //附件提供
运行时 可能会产生缺少mime.types的错误,直接将ubuntu的/etc/mime.types复制到D1的ETC目录。
HDMI的开关
//找到驱动定义 enum disp_output_type { DISP_OUTPUT_TYPE_NONE = 0, DISP_OUTPUT_TYPE_LCD = 1, DISP_OUTPUT_TYPE_TV = 2, DISP_OUTPUT_TYPE_HDMI = 4, DISP_OUTPUT_TYPE_VGA = 8, DISP_OUTPUT_TYPE_EDP = 32, /*16 for vdpo*/ };
打开HDMI
cd /sys/kernel/debug/dispdbg echo disp0 > name; echo switch1 > command; echo 4 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;
关闭HDMI
cd /sys/kernel/debug/dispdbg echo disp0 > name; echo switch1 > command; echo 0 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;
注意:echo 1 4 0 0 0x4 0x101 0 0 0 8 > param;——此处的第一个参数 1 代表MIPI-DSI输出,如果是要切换为HDMI输出,则改为 4,关闭则改为0
GPIO 操作
echo 65 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio65/direction echo 1 > /sys/class/gpio/gpio65/value
