兄弟们我离职了，以后看什么时候有机会用上全志的芯片就来问问吧，不过就我这一圈体验下来，只能说代码做得勉强还行，就这样。

没搞过开发板做服务器，老板要求开发板实现屏幕采集，usb键盘鼠标转发，这就涉及开发板视频流推流的问题，预想是的采集后h264编码发送。
现在找着的方法是用nginx服务器+fastcgi做程序和服务器的数据共享，这些都是openwrt自带有的组件，但问题来了，开发板的程序要想用Fastcgi要libfcgi库，我找了半天就找到几个patch文件，具体的库究竟是在哪完成的编译的？？

自己完成libfcgi的交叉编译还是颇有难度，没搞定。
可以用的是cgi，但它每次都要创建线程再删除，性能实在太差了。

@kunyi 开ISP当然可以用，现在关ISP也能用了，就是抓图的时候像素格式没设置对

@xiaowenge 那是，性价比这块全志芯片还不错的，如果能自己搞定软件的话... 确实难就难在这，我这里东西都做得差不多了，只是老板想叫我去做bios编程的工作内容，我不同意，试用期也就这样了。

@zm12138 只看报错是说/usr/是只读文件系统，换个路径看看？

@vincent1 看了看还是web socket挺合适的，很契合本地C语言的数据到网页js

@zm12138 /tmp文件夹谁都能填，或者你 自己创建一个 mkdir /mydir
chmod 777 /mydir

兜兜转转又回到了RK628驱动，老板要求的，因为它比较新，有公司可以问，它做hdmi转mipi csi只能输出YUV422格式像素，驱动对应的是 MEDIA_BUS_FMT_UYVY8_2X8 ，抓图例程用/root/sample_driverVipp，不过我发现实际运行起来后被设成了MEDIA_BUS_FMT_SBGGR8_1X8，只有用 V4L2_PIX_FMT_SBGGR8作为像素格式不会报错，不过也没出图，看mipi clk有1.2V波形，这该咋办？

讲真卡在这里真的太久了，哎，烦

驱动里设置

/*
 * Store information about the video data format.
 */
static struct sensor_format_struct sensor_formats[] = {
	{
		.desc      = "UYVY 4:2:2",
		.mbus_code = MEDIA_BUS_FMT_UYVY8_2X8, /*.mbus_code = MEDIA_BUS_FMT_SBGGR10_1X10, */
		.regs      = 0,
		.regs_size = 0,
		.bpp       = 4,
	},
};
#define N_FMTS ARRAY_SIZE(sensor_formats)

/*
 * Then there is the issue of window sizes.  Try to capture the info here.
 */

static struct sensor_win_size sensor_win_sizes[] = {
	{
		.width      = 1920,
		.height     = 1080,
		.hoffset    = 0,
		.voffset    = 0,
		.hts        = 2200,
		.vts        = 1125,
		.pclk       = 74250000*2,
		.mipi_bps   = 375 * 1000 * 1000,
		.fps_fixed  = 60,
		.regs       = 0,
		.regs_size  = 0,
		.set_size   = NULL,
	},
};

修改了sunxi_isp.c和vin_tdm.c，增加对MEDIA_BUS_FMT_UYVY8_2X8的支持，设备树里设置 sensor0_isp_used = <0>; sensor0_fmt = <0>;

static struct tdm_format sunxi_tdm_formats[] = {
	{
		.code = MEDIA_BUS_FMT_UYVY8_2X8,
		.input_type = INPUTTPYE_8BIT,
		.input_bit_width = RAW_8BIT,
		.raw_fmt = BAYER_RGGB,
	},{
...

static struct isp_pix_fmt sunxi_isp_formats[] = {
	{
		.fourcc = V4L2_PIX_FMT_UYVY,
		.mbus_code = MEDIA_BUS_FMT_UYVY8_2X8,
		.infmt = ISP_BGGR,
		.input_bit = RAW_8,
	},{

使用camerademo setting 抓图

图片格式YUV422，宽高19201080理论上大小是19201080*2=4147200字节，实际上得到的图是4177920字节，多出来啥了？

用yuvplayer看图，颜色设置YUV422，能看到图片还白加点偏移的颜色的

@awwwwa 看来设备树里关ISP只是不使用硬件ISP但set_fmt还是会在代码里面过过，我开了ISP就出现isp error了，现在看来抓图应该是抓成功了，但数据格式不太对，有颜色，颜色都有偏移，文件大小也稍大了些，理论上192010802=417200字节，实际上是4177920字节，多出来什么了？

我截图桌面用ffmpeg转成yuv422图片确实是417200字节

@xiaowenge 那是，性价比这块全志芯片还不错的，如果能自己搞定软件的话... 确实难就难在这，我这里东西都做得差不多了，只是老板想叫我去做bios编程的工作内容，我不同意，试用期也就这样了。

兄弟们我离职了，以后看什么时候有机会用上全志的芯片就来问问吧，不过就我这一圈体验下来，只能说代码做得勉强还行，就这样。

@sunxi vi /etc/init.d/S40network
学一下vi编辑器，用vi来改

或者你在电脑改好这个文件，adb传到开发板
adb push ./S40network /etc/init.d/S40Network

@sunxi 修改脚本/etc/init.d/S40network
添加 ifconfig eth0 up
ifconfig eth0 "192.168.1.1" netmask "255.255.255.0"

参考例子

#!/bin/sh
#
# Start the network....
#

# Debian ifupdown needs the /run/network lock directory
mkdir -p /run/network

MAC_ADDR="`cat /sys/class/sunxi_info/sys_info | awk '$1=="sunxi_chipid" {print $3}' | sed 's/../&:/g' | cut -c1-14`"

ipaddr="192.168.20.162"
netmask="255.255.255.0"

case "$1" in
  start)
        printf "Starting network: "
        /sbin/ifup -a
        [ $? = 0 ] && echo "OK" || echo "FAIL"
        /sbin/ifconfig eth0 hw ether "00:$MAC_ADDR"
        #udhcpc -b -R &
        ifconfig eth0 up
        ifconfig eth0 "$ipaddr" netmask "$netmask"
        ;;
  stop)
        printf "Stopping network: "
        /sbin/ifdown -a
        [ $? = 0 ] && echo "OK" || echo "FAIL"
        ;;
  restart|reload)
        "$0" stop
        "$0" start
        ;;
  *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
esac

exit $?

可以修改openwrt/target/v853/v853-vision/busybox-init-base-files/etc/init.d/S40network，这样每次打包都会把这个脚本改好

@awwwwa 投入boa的怀抱了，反正我只要能把网页发出来就好了

@awwwwa 还是一样的，luci加进来了，官网的配置暂时没找着这个内容
root@TinaLinux:/# luci-
luci-bwc luci-reload
root@TinaLinux:/# /etc/init.d/uhttpd start
root@TinaLinux:/# /etc/rc.common: line 128: uci_load: not found

root@TinaLinux:/#

root@TinaLinux:/# /etc/init.d/uhttpd start
root@TinaLinux:/# /etc/rc.common: line 128: uci_load: not found

不知道怎么添加uci的调用，没找到uci的配置路径，在menuconfig下直接搜索uci信息太多，搜索uci_load就没信息

换了个企业版的V853SDK，menuconfig 没有lighttp可以选，uhttpd找半天没找着教程，这玩意哪有比较全面的配置步骤啊？只要能把html网页发布出去就行了

@zm12138 /tmp文件夹谁都能填，或者你 自己创建一个 mkdir /mydir
chmod 777 /mydir

@zm12138 只看报错是说/usr/是只读文件系统，换个路径看看？
