疑问

swann下有的命令root下没有arm-xxx。
编译uboot时，一直出现xxx文件不存在的错误，竟然是因为文件路径名长度的原因？？？！！！
HI3516DV300 HITOOL 等待boot启动超时，单板上无fastboot或当前fastboot无法启动

原来是厂商给的uboot有问题呀😅
Hitools烧写时，uImage能通过网口烧写，rootfs不行。原因是hitool软件bug，烧完uImage依旧占用69TFTP端口。
TFTP服务器启动失败,端口69可能被占用!

由于Clion使用了远程开发功能，把Clion关闭解决问题。。
出厂镜像是imx325.。。。imx335需要自己编译
rtsp-live555

海思hi3516dv300开发–live555交叉编译

hi3518e移植live555实现点播_网络_chengqingyao的博客-CSDN博客

　　POD document had syntax errors at /usr/bin/pod2man line 71.
　　make： *** ［install_docs］错误 255
　　原因分析：这是由于 OpenSSL 1.0.1e 与 perl5.18 不兼容。
　　解决方法：
　　1、有人验证安装 perl 5.16 可以兼容，安排低版本 perl 5.16 可以解决问题。
　　2、删除 pod2man 文件：
　　sudo rm /usr/bin/pod2man

解决方法：另外hi3516dv300的uart3有个bug，缺少对UART3时钟的配置 kernel/linux-4.9.y/
vi drivers/clk/hisilicon/clk-hi3516dv300.c文件中

static struct hisi_gate_clock hi3516dv300_gate_clks[] 在132行添加一项：

1	`{ HI3516DV300_UART3_CLK, "clk_uart3", "uart_mux3",CLK_SET_RATE_PARENT, 0x1b8, 3, 0, },`

如下所示

static struct hisi_gate_clock hi3516dv300_gate_clks[] __initdata = {
			/* fmc */
			{ HI3516DV300_FMC_CLK, "clk_fmc", "fmc_mux",
				CLK_SET_RATE_PARENT, 0x144, 1, 0, },
			/* mmc */
			{ HI3516DV300_MMC0_CLK, "clk_mmc0", "mmc0_mux",
				CLK_SET_RATE_PARENT, 0x148, 1, 0, },

			{ HI3516DV300_UART2_CLK, "clk_uart2", "uart_mux2",
				CLK_SET_RATE_PARENT, 0x1b8, 2, 0, },
			// 132行增加uart3的配置
			{ HI3516DV300_UART3_CLK, "clk_uart3", "uart_mux3",
				CLK_SET_RATE_PARENT, 0x1b8, 3, 0, },
			{ HI3516DV300_UART4_CLK, "clk_uart4", "uart_mux4",

变量命名

1、定义枚举类型，注意字母后面的E。

typedef enum hiHI_MPP_WDR_MODE_E

{
HI_MPP_WDR_MODE_NONE = 0,
HI_MPP_WDR_MODE_BUILT_IN,
HI_MPP_WDR_MODE_2To1_LINE,
HI_MPP_WDR_MODE_2To1_FRAME,
HI_MPP_WDR_MODE_2To1_FRAME_FULL_RATE,
HI_MPP_WDR_MODE_3To1_LINE,
HI_MPP_WDR_MODE_3To1_FRAME,
HI_MPP_WDR_MODE_3To1_FRAME_FULL_RATE,
HI_MPP_WDR_MODE_4To1_LINE,
HI_MPP_WDR_MODE_4To1_FRAME,
HI_MPP_WDR_MODE_4To1_FRAME_FULL_RATE,
HI_MPP_WDR_MODE_BUTT

}HI_MPP_WDR_MODE_E;

定义枚举类型的变量，注意变量前面的en，应试enum的缩写。

HI_MPP_WDR_MODE_E enWdrMode;

2、定义结构体类型。

typedef struct hiHI_MPP_SENSOR_ATTR_S
{undefined
HI_S32 s32FrameRate;
HI_MPP_RESOLUTION_S stResolution;
HI_MPP_WDR_MODE_E enWdrMode;
} HI_MPP_SENSOR_ATTR_S;

注意定义结构体变量时在变量的前面加上“st” ，应是struct的缩写吧。

HI_MPP_SENSOR_ATTR_S stSensorAttr;

3、定义基本类型的别名。

typedef unsigned char HI_U8;
typedef unsigned short HI_U16;
typedef unsigned int HI_U32;

typedef signed char HI_S8;
typedef short HI_S16;
typedef int HI_S32;

HI_S32 s32Ret；//define a int variable,notify “s32”
自启–etc/inittab
