荔枝派Nano的linux5.2版本主线下载及编译(支持USB设备与主机模式)

下载与编译linux5.2

下载linux5.2:https://github.com/Lichee-Pi/linux/archive/nano-5.2-tf.zip
解压:

unzip nano-5.2-tf.zip ./

进入linux目录下:

cd linux-nano-5.2-tf

使用荔枝派Nano默认配置:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make sunxi_defconfig  ###使用默认配置

编译linux:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j4 ###四进程编译

打补丁

patch -p1 < usb.patch

配置文件.config下载(包括已编译好的可以镜像、设备树)

重新编译dtb

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- dtbs -j4

重新编译内核

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j4

下载到TF卡运行(如下图):

uboot和文件系统自行安装到tf卡。

HOST模式测试(如下图):
插入U盘

设备模式测试(如下图):

1、PC端设置

USB线连接PC(linux主机,Windows没找到驱动),如下:

ens35u1为设置IP:
ifconfig ens35u1 192.168.1.120

2、F1C100S板子端设置
