@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。

xjy_5

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

xjy_5

@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

xjy_5

@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

xjy_5

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

xjy_5

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

xjy_5

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

xjy_5

@zm12138 只看报错是说/usr/是只读文件系统，换个路径看看？

xjy_5

@awwwwa 我这边想走硬件获取视频输入好适配H264编码，像素格式YUV422P，默认mpp的程序里是不支持这个格式的，原来的就只有YUV420，请问有哪个设备的SDK适配了YUV422P像素格式的摄像头吗？我参考参考程序
在videoInputHW.c里有

xjy_5

@awwwwa 通过sample_virvi抓到的图比sample_driverVipp小一半，应该是哪没设置好吧

xjy_5

@awwwwa 现在又开始烦了，我在sample_driverVipp里面用 V4L2_PIX_FMT_YUV422P 抓图，很顺利，不过得到的是1920x1088的图片，然后用sample_virvi抓图，怎么抓出来的图都是红红绿绿蓝蓝的，不过出来的图是1920x1080的了，理论上我应该选MM_PIXEL_FORMAT_UYVY_PACKAGE_422就对了

xjy_5

@xjy_5 成了，用19201088像素格式查看数据就行了，为什么会是19201088啊？？

xjy_5

驱动里设置

/*

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)

/*

		.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

xjy_5

@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

xjy_5

@awwwwa 果然这邪门方法还是不想，出图了，黑白色搞不定，除非继续深挖改写代码，这样这块只会变得越来越像屎山，有没有什么靠谱的办法啊。

xjy_5

@awwwwa 能看到有点彩色，但和图像有偏移

xjy_5

@awwwwa 出图了，黑白色，我的天，今晚做梦都能笑出来了，哈哈
主要改了sunxi_isp_formats 和 sunxi_tdm_formats ，添加了含MEDIA_BUS_FMT_UYVY8_2X8的定义


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_YUV422P,
		.mbus_code = MEDIA_BUS_FMT_UYVY8_2X8,
		.infmt = ISP_BGGR,
		.input_bit = RAW_8,
	},{
          ...

用yuvplayer看的图

xjy_5

@awwwwa 要是有办法绕掉sunxi_isp.c就好了，sunxi_csi_formats里都有MEDIA_BUS_FMT_UYVY8_2X8的定义了

xjy_5

@awwwwa reset脚，中断脚我在设备树其他地方定义，在驱动的sensor_init里获取来用了，也能用，iic是用rk628原本的regmap，也能用，不过这些放一边先。
驱动里设置 MEDIA_BUS_FMT_UYVY8_2X8 用camerademo抓图应该设置那个像素格式？使用gc2053的经验告诉我，设备树里关掉isp后抓图设置的像素格式应该和驱动里设置的一致，那MEDIA_BUS_FMT_UYVY8_2X8 对应的是哪个？

@awwwwa 666，真是来帮大忙了

xjy_5

@awwwwa 是不是要改ISP驱动啊？还是说应用层调用的时候有什么办法不使用ISP?

xjy_5

驱动里的设置

根据VIN_LOG_FMT的debug信息，抓图时它会调用到sunxi_isp_subdev_set_fmt函数，而sunxi_isp_formats的定义并未包含YUV格式像素，我想问题应该就在这，但是不敢乱改代码，也不知道怎么改

@awwwwa 难怪这么久都没有成，一开始就错了，呜呜呜...
现在又有了另一个问题，TC358743里有另一个模式使用的是MEDIA_BUS_FMT_RGB888_1X24，这个V853支持吗？现在我找了半天大概也是不支持

xjy_5

实在不知道这些代表什么意思，该查什么词语？现在找到相关文档但是全英文，有没有国人总结的教程啊

xjy_5

因为给的V853 sensor支持列表全都是raw格式的摄像头，我再在/tina-v853-open/lichee/linux-4.9/drivers/media/platform/sunxi-vin/modules/sensor文件夹下搜索mipi_bps，因为mipi摄像头肯定要设置这个参数，结果只找到rn6854和nvp名称开头的驱动是使用YUV像素的，但这些传感器在kernel_menuconfig里都不能选中。
我再仔细看了看教程，用到的名词是"YUV 的并口模组"，用的是例子是OV5640，它的驱动里没有设置mipi_bps，所以，，是我误解了？V853的MIPI CSI不能接收YUV格式像素？

xjy_5

@nzdzhd 看看驱动的教程，我记得改改设备树就能用了，不过没实际弄过

xjy_5

@xjy_5 我用的是100ask的开发板

xjy_5

我所知道的是设备树里写 sensor0_fmt = <0>;
驱动里设置.mbus_code = MEDIA_BUS_FMT_UYVY8_2X8,
应用层时使用 V4L2_PIX_FMT_YUV422P
初次以外还需要注意啥？

我现在的报错是vin is not support this pixelformat，看源码它会调用好几次vin_find_format，前面几次都查询成功了，直到开始查找 MEDIA_BUS_FMT_SBGGR8_1X8 ，报错退出，我还不清楚这个函数干啥的，得看一会。顺带一提，我设置的MEDIA_BUS_FMT_UYVY8_2X8是0x2006，在就找到了，为什么会要找其他格式像素？

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

xjy_5

@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

xjy_5

RK628驱动里的 format设置

static struct sensor_format_struct sensor_formats[] = {
	{
 		.desc = "YUV 4:2:2",
		.mbus_code = MEDIA_BUS_FMT_UYVY8_2X8,
		.regs = NULL,
		.regs_size = 0,
		.bpp = 2,
		},
};

xjy_5

@xjy_5 成了，用/root/sample_driverVipp 0 1920 1080 5 60 1 1 30 /root/pic可以抓图，注意像素格式要和驱动里的一样是SBGGR10就行，这里对应的是V4L2_PIX_FMT_SBGGR10，

但是我用RK628还是抓不到，RK628驱动设置的是 MEDIA_BUS_FMT_UYVY8_2X8 ,对应的像素格式是V4L2_PIX_FMT_UYVY？？

奇怪的是这里ouput fmt居然是NULL，以前都是INPUT fmt NULL

xjy_5

@kunyi 现在用原厂摄像头，关闭ISP，出现了同样的错误，理论上应该不会有错才对，也有可能是我用的例程不对

xjy_5

我移植HDMI转MIPI驱动，不论是RK628还是TC358743，开启最后都会出现vin_pipeline_try_format failed无法解决，
而开启ISP，又会去用GC2053的isp 配置文件，出现 [VIN_ERR]isp0 configuration error

现在还是买来GC2053参考参考，照着教程走最后确实出视频了，但如果我在设备树里写sensor0_isp_used = <0>;，就一样会出现SET_FMT error

搞得我看了半天mbus_code，那gc2053关ISP还有什么地方要改？

xjy_5

@kunyi 那也就是说可能已经在传图像了？？不过我一直都没出过图，坏图也没见，就是不通，资料匮乏啊。

xjy_5

最近有人离职，要先做其他东西了，这个功能要先停住了。

xjy_5

@awwwwa 又有新发现，CLKP,CLKN在初始化TC358743前和其他数据脚一样维持在1.2V，初始化后就变成了0.2V，后来我再开测试程序，它还是保持0.2V，其他引脚则产生波形

xjy_5

在此之前没学过MIPI的内容，现在只知道它的引脚定义P , N 对的差分信号做数据传输，我移植TP358743驱动到现在IIC已经通了，MIPI数据脚也有信号了，但是MIPI_CLKP, MIPI_CLKN并没有信号，这个接口在工作时是采集端控制时钟脚还是主控端在控制时钟脚啊？另外我用的是sample_virvi验证抓图功能，但从来没成功过，每次都会有这句

[ISP]video0 fd[14] ve_online_en=0, dma_buf_num=0
[ISP_ERR]video_set_fmt, line: 194,VIDIOC_S_FMT error!

set_fmt 失败！！到底咋样才能成啊？？
另外，求一波关于mipi的教程，感谢

xjy_5

@awwwwa 现在又发现其他问题，有时候会出现报错

tc_write8 failed, addr:8514 value:0x00

或者

tc_write8 failed, addr:8543 value:0x32

然后mipi信号就不会发生。
有时候mipi信号有了，但是只在数据线上有信号，CLKP,CLKN没信号

xjy_5

@awwwwa 其实我挺疑惑 mbus_code到底选哪个，看了规格书和其他tc358743的驱动都和这个芯片不太配的样子。

xjy_5

@awwwwa 驱动运行起来了，mipi也有信号，运行sample_virvi抓图失败，报错信息入下，讲真星期五没什么心情写代码了，今天能看多少看多少吧。顺带说一下，我实在不清楚reset函数是什么时候调用的，我把驱动里reset脚的操作放在了PWR_ON里，把sensor_probe里的iic操作放到了sensor_init里。这样就能确定寄存器是重置后配的了

@awwwwa 原来是把TWI的驱动能力改成3，上下拉去掉就可以了

	twi0_pins_a: twi0@0 {
		allwinner,pins = "PA16", "PA17";
		allwinner,pname = "twi0_scl", "twi0_sda";
		allwinner,function = "twi0";
		allwinner,muxsel = <4>;
		allwinner,drive = <3>;//IO驱动能力: Level 3
		allwinner,pull = <0>;//不需要内部上下拉电阻
	};

理清了点头绪但又没完全有，现在发现是这个if不满足，一直都没有读取文件，是venc没准备好吗，还得研究一段时间。

用ffpmeg指令制作了yuv360p视频

ffmpeg -i xk360.mp4 -s 640x360 -pix_fmt yuv420p xk360.yuv

修改sample_venc.conf，只修改了开头几个选项

@sofia 你看电路图呗，100ask上是把usbhub和otg接口用一个开关芯片一起接到typec，又用两个电阻把otg接口接到typec，我用的时候老是不稳定，现在把usbhub摘掉了，稳多了。

@sofia 你用的什么版本开发板，我用的100ask，otg口和hub扩展芯片电路上冲突，拆了hub扩展芯片才好用，你看看你的有没有这个问题

xjy_5

总算是搞定usb 做gadget老是不稳定的问题了，把usb hub芯片拆下来就行了，看电路它可能和usb otg引脚互相干扰，没想到是直接原因啊

xjy_5

@xjy_5 解决了，真是个玄学问题，我把usb线换成原装的就正常了，另买的偶尔用得了，试出了点经验，开发板开机后再插usb容易识别成功，otg口转换功能前先拔掉usb再操作，再用下面的命令重置usb口，更容易成功

cat /sys/devices/platform/soc/usbc0/usb_host
cat /sys/devices/platform/soc/usbc0/usb_device

xjy_5

很奇怪的现象，我把开发板许多不用的功能裁剪掉了，但是otg口工作不正常了，之前用它gadget配置都是能用的，但现在死活不识别，插电脑上就显示多了个hub口，还能识别开发板上hub插的U盘，这是我改掉了什么配置？？

xjy_5

@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

xjy_5

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。

xjy_5

好了，总算能生成的ko文件了，把tc358743文件夹放在/tina-v853-open/kernel/linux-4.9/drivers/media/platform/sunxi-vin/modules/sensor/，修改 Makefile

再修改tc358743文件夹内的makefile

还要配置一下make kernel_menuconfig，搜索dv_timi，选第一个

这就能生成.ko文件了

xjy_5

@awwwwa 没事了，看到开机就调用了

xjy_5

@awwwwa 我改了设备树，在sensor文件夹下添加了tc358743，修改了makefile

编译是通过了，不过我怎么调用？

xjy_5

@awwwwa 谢谢大哥！祝大哥福如东海，寿比南山，永远不死，吃嘛嘛香！给大哥递茶

xjy_5

@awwwwa

手册上说每条land支持1.2Gbps的带宽，也就是说最高频率是600MHZ，但RK628最低是到750MHZ的，用不了，现在看看tc358743怎么样了

xjy_5

@awwwwa V853的mipi csi总线到不了750MHZ，这是RK628的最低频率。禁用ISP的话我还有什么方法调用MIPI CSI？在应用层我只知道ISP的应用接口。

xjy_5

@awwwwa 真的可以不用ISP就取出CSI的数据？？

xjy_5

我在移植RK628D屏幕采集模块到v853上，是CSI 4land接口，开机后电脑已经识别到第二个显示器了

不过信号采集一直有问题，isp一直是config error，我并不清除它究竟是在哪config的
驱动程序里的参数配置如下，IIC是移植RK628驱动原有的regmap操作的，没用到原本的iic操作函数

这个/mnt/extsd/isp0_1920_1080_60_ctx_saved.bin文件是怎么来的，应该往哪个方向排故？

xjy_5

开启usbip Client功能，
make kernel_menuconfig

make menuconfig，搜索usbip

编译报错 error: “_GNU_SOURCE“ redefined [-Werror]
修改文件 tina-v853-open/out/v853/100ask/openwrt/build_dir/target/linux-v853-100ask/usbip-2.0/src/usbipd.c
把

#define _GNU_SOURCE

改成

#ifndef _GNU_SOURCE
    #define _GNU_SOURCE
#endif

又报错 libtool: Version mismatch error. This is libtool 2.4, but the

到tina-v853-open/out/v853/100ask/openwrt/build_dir/target/linux-v853-100ask/usbip-2.0
输入指令

cd ~/tina-v853-open/out/v853/100ask/openwrt/build_dir/target/linux-v853-100ask/usbip-2.0
autoreconf -ivf

编译通过，后头又有啥问题再写

xjy_5

@awwwwa 感谢回复，现在可以用了，我都不知道有这些配置
现在的make menuconfig 的配置

make kernel_menuconfig的配置，搜loop，选的第二个

xjy_5

@awwwwa 修改了分区大小了，现在打包能放下了，但结果还是说 cannot find an unused loop device

xjy_5

@awwwwa 我在 make menuconfig 后，搜索losetup，修改了些配置

把PACKAGE_schroot设置为M，SCHROOT_LOOPBACK设置成y，编译后开机losetup结果

root@TinaLinux:~# losetup -f a.img
losetup: cannot find an unused loop device

是另外的问题了，如果PACKAGE_schroot设为y，pack就会说rootfs太大
ERROR: dl file rootfs.fex size too large
ERROR: filename = rootfs.fex
ERROR: dl_file_size = 49408 sector

xjy_5

应该是不支持这个命令，losetup -h 都报错，这个命令运行内容应该是空的

xjy_5

但mass_stor.img明明就在当前目录下了，是缺少什么编译库吗？

xjy_5

@sofia 测试USB的APP的源码已经放上来了。我在串口命令行运行app马上就会从开发板的usb发出‘a’，所以就打在命令行上了

xjy_5

妈呀，突然发现这部分内容在v853系统开发手册里面有说，但我之前都不知道！不过里面没有给出文件路径，只说了可以修改这些定义，有点云里雾里

xjy_5

现在有点眉目了，看了一上午的gadget初始化流程，困得不行，现在V853已经可以做HID设备发出'a'了，但不确定这么改会不会出什么bug，主要是修改了sunxi_udc的默认配置
修改了 sunxi_usb\include\sunxi_udc.h 的ep2的相关内容,把bulk改成了int，把ep_fifo的偏移地址做了修改

static const char ep0name[] = "ep0";
static const char ep1in_bulk_name[] = "ep1in-bulk";
static const char ep1out_bulk_name[] = "ep1out-bulk";
static const char ep2in_int_name[] = "ep2in-int";
static const char ep2out_int_name[] = "ep2out-int";
static const char ep3_iso_name[] = "ep3-iso";
static const char ep4_int_name[] = "ep4-int";
static const char ep5in_bulk_name[] = "ep5in-bulk";
static const char ep5out_bulk_name[] = "ep5out-bulk";

static const struct sw_udc_fifo ep_fifo[] = {
{ep0name, 0, 512, 0},
{ep1in_bulk_name, 512, 1024, 1},
{ep1out_bulk_name, 1536, 1024, 1},
{ep2in_int_name, 2560, 512, 0},
{ep2out_int_name, 3584-512, 512, 0},
{ep3_iso_name, 4608-1024, 1024, 0},
{ep4_int_name, 5632-1024, 512, 0},
{ep5in_bulk_name, 6144-1024, 1024, 1},
{ep5out_bulk_name, 7168-1024, 1024, 1},
};

sunxi_usb\udc\sunxi_udc.c 也是类似，对应的内容在sunxi_udc的 ep[3],ep[4]

.ep[3] = {
	.num			= 2,
	.ep = {
		.name		= ep2in_int_name,
		.ops		= &sunxi_udc_ep_ops,
		.maxpacket	= SW_UDC_EP_FIFO_SIZE,
		.maxpacket_limit = SW_UDC_EP_FIFO_SIZE,
		.caps	= USB_EP_CAPS(USB_EP_CAPS_TYPE_INT,
				USB_EP_CAPS_DIR_IN),
	},
	.dev		        = &sunxi_udc,
	.bEndpointAddress   = (USB_DIR_IN | 2),
	.bmAttributes	    = USB_ENDPOINT_XFER_INT,
},

.ep[4] = {
	.num			= 2,
	.ep = {
		.name		= ep2out_int_name,
		.ops		= &sunxi_udc_ep_ops,
		.maxpacket	= SW_UDC_EP_FIFO_SIZE,
		.maxpacket_limit = SW_UDC_EP_FIFO_SIZE,
		.caps	= USB_EP_CAPS(USB_EP_CAPS_TYPE_INT,
				USB_EP_CAPS_DIR_OUT),
	},
	.dev		        = &sunxi_udc,
	.bEndpointAddress   = (USB_DIR_OUT | 2),
	.bmAttributes	    = USB_ENDPOINT_XFER_INT,
},

这就完了，然后重新编译，打包，找个了hid gadget键盘的例程，简化了下，只发送‘a’

上传上面的代码编译成app，chmod 给予运行权限，我这里是编译成了hidapp

chmod 777 ./hidapp

kernel/linux-4.9/Documentation/usb/gadget_hid.txt也有例程，但比较复杂全面，一时半会我也看不懂，

然后就是指令
killall adbd 2>/dev/null
setusbconfig hid
cat /sys/devices/platform/soc/usbc0/usb_host
cat /sys/devices/platform/soc/usbc0/usb_device
先关掉ADB程序，再开脚本设置hid键盘，现在就没报错了，但电脑还是没识别到键盘，需要转换usb口到host再转到device才能用，这个时候设备管理器就能看到新键盘了

app测试

说一下其他问题，我用的adb上传文件，每次都要cat /sys/devices/platform/soc/usbc0/usb_host
cat /sys/devices/platform/soc/usbc0/usb_device才能用，完了要是拔插usb口，虚拟机的usb就会卡死再也无法识别，电脑也关不了机，只能强制重启，这个问题很影响调试，有办法解决吗？

为了了解究竟发生了什么，在这三个文件里加了打印来确定哪个if没通过

linux-4.9/drivers/usb/gadget/function/f_hid.c
linux-4.9/drivers/usb/gadget/epautoconf.c
linux-4.9/drivers/usb/gadget/udc/core.c

出错的地方是 f_hid.c-> hidg_bind -> usb_ep_autoconfig

而usb_ep_autoconfig用到的是 epautoconf.c -> usb_ep_autoconfig_ss，usb_gadget_ep_match_desc 没找着匹配的端点

最后是在gadget/udc/core.c的usb_gadget_ep_match_desc函数没通过if (!ep->caps.type_int)

原来是没通过支持中断传输的检查

linux4.9内核的gadget好像有BUG，不能模拟hid设备，V853的sdk刚好就是这个版本的内核，我自己试过确实不行，查了资料找到了远古帖子，好像有补丁能用，但那帖子里的链接已经失效了，我也不懂怎么找补丁，有人有解决办法吗？

@awwwwa 感谢回复！这确实是个办法，不过fifo full是溢出的意思吧？

移植rk628_csi_v4l2驱动到V853上，算是完成了，用命令/sample_driverVipp 0 1920 1080 2 30 0 10 /mnt，能测到MIPI信号了，回复如下

gc2053是原驱动文件的名称，直接在这个文件里改的
报错代码是写在sunxi_isp.c，static irqreturn_t isp_isr(int irq, void *priv)里的，求大佬给个排查思路

写指令前用了 echo "" > /sys/kernel/config/usb_gadget/g1/UDC 关闭ADB，还是说要其他方法重置gadget?

@moider 固件对了照这个教程https://d1.docs.aw-ol.com/study/study_4compile/ 的按住fel按键烧写

xjy_5

解决了，问客服要的网盘里的固件才能启动，在https://d1.docs.aw-ol.com/d1_dev/下的固件用不了

xjy_5

现在PhoenixSuit能用了，烧写进度条满了之后板子重启卡住，烧写软件会再次尝试烧写也卡住，烧的是 D1-H哪吒HDMI测试固件20210804（开机HDMI就有小企鹅启动logo） .img

xjy_5

全志D1-H开发板刚到，烧写就出了问题，用的固件是用repo下载编译出来的，刚开始PhoenixSuit还能用，但烧写着板子重启就卡住了，然后就一直连接不上设备了，开发板再开机串口也是打印同样的内容。按FEL再按RST键也连接不上。在虚拟机ubuntu14用LiveSuit烧写能烧，但是进度条到100%会 Kill Timer,再开机串口的内容和之前一样，这该怎么解决啊!替代文字

xjy_5

水贴，来下全志D1开发板资料的，准备搞个远程桌面和能远程装机的的中继服务器
