有个疑问，如果选择mipi_csi而不是csi parall
vinc0_csi_sel = <0xff>;
vinc0_mipi_sel = <0>;
还是
vinc0_csi_sel = <0>;
vinc0_mipi_sel = <0>;
这样？

抓了系统LOG日志，failed to open /dev/video2，系统莫名其妙去打开video2，实际上的节点只有video0和video1

感觉是相机的进程被系统杀死了，然后又重新启动进程

如何利用v4l2底层调用获取图片？

目前的问题是pair 和trust之后，connect 设备，连上之后又自动断开了。
不能保持连接。

刚开始勾的bluez 3.x编译，后来改成bluez 5.x,任然没有bluetoothctl，找了好久没找到原因，干脆make clean之后重新make，终于有bluetoothctl了

绑定之后能连上发数据吗？

折腾了还是没出来，Realtek Three-wire UART (H5) protocol support，先不管了，勾上这个Three-wire UART (H5) protocol support后试试先

果然没有报H5 协议的错误

根据自己选择的串口，设备树添加相关的定义

TF卡走线受到感染或者太长了

@晕哥

试了V3S插着TF卡短接MISO进不了fel模式

网络不一定能用，应该要用USB比较合适

不修改内核的情况下，怎么设置watchdog 的时间呢？

搞定了，引脚定义没放在pinctrl下面

@晕哥

我用的是V3S linux5.2
代码复制过去的，event出不来，原有的matrix key是evet0，lradc是event1，触摸屏是event2，串口2也注释掉了，开机没有打印PB2中断对应的inputx

@Quotation

请问怎么读LRADC寄存器电压值？

没有这个文件，也没有/sys/class/gpio/gpio64这个目录

估计是读写权限的问题，没有root权限

一开始用PE22作为中断脚申请不到，后面改成PB3就可以了

input: generic ft5x06 (82) as /devices/platform/soc/1c2ac00.i2c/i2c-0/0-0038/input/input1

怎么设置分辨率的？lv_conf.h没看到有
#define LV_HOR_RES_MAX          (480)  //屏幕水平宽度 根据实际使用修改
#define LV_VER_RES_MAX          (320)  //屏幕垂直高度 根据实际使用修改

检查TF卡槽触点及焊接有没有问题

同一张就卡插到zero开发板，播放音乐正常，而做的板子只有滋滋的声音

v3s做板遇到同样问题，用zero开发板可正常开机，是不是TF卡里V3S太远了，文件系统挂载不了？

10.1寸   RGB  50pin屏幕很常见，不过要对照数据手册，不同厂家  VGH VGL VCOM 背光等电源都会有些不同，一不小心就会把屏幕烧了

我调的是
YT101ISM-45B
HZ-TFT101BT001

dev看下是不是有两个fb，会不会是还有一个RGB接口的屏幕没删掉

LCD_CLK用示波器测得25MHz，明明设置的是51.2MHz,uboot打印也是

UBOOT 修改分辨率为1024x600

296 #define CONFIG_SUNXI_MAX_FB_SIZE (2 << 20)

改为

296 #define CONFIG_SUNXI_MAX_FB_SIZE (3 << 20)

接上屏幕依然没有显示，换回5寸 800*480还是能显示
执行fb-test

# ./usr/bin/fb-test
fb-test 1.1.0 (rosetta)
fb res 1024x600 virtual 1024x600, line_len 4096, bpp 32

是的，在找背光驱动方案

目前状态是背光微弱，屏幕没有显示内容

40PIN转50PIN只是硬件转换吗？

dev目录有没有fb，可以用工具fb-test测试

用V3S自带的display engine

V3S的板子还有吗？

开机log有没有输出注册fb信息？dev目录下看看有没有fb设备

linux5.2 文件树&de打开了，录制视频屏幕还是没反应

我想要的效果是拍照时候先用屏幕对好位置，然后再点击按下快门，拍照成图片，把摄像头图像通过v4l采集显示到fb上

能否指点一下，谢谢

解决 https://blog.csdn.net/qulang000/article/details/114686525

@shuiyihang
是怎么解决的？我也遇到初始化后雪花屏，执行cat之后是白屏

USB口供电问题，使用直流电源可以了，就是拍照一团黑，只看到大概轮廓

没，我再试试，谢谢

已经添加了C++ support，但是还是没有

重新折腾了好几天，测试freedtds中tsql可以连接到MS数据库，但交叉编译unixodbc后，在移植freetds时，.configure加上--with-unixodbc=/usr/local/unixodbc

报错
./configure: line 16574: /usr/local/arm/unixODBC/bin/odbc_config: cannot execute binary file: Exec format error
./configure: line 16575: /usr/local/arm/unixODBC/bin/odbc_config: cannot execute binary file: Exec format error
configure: error: /sql.h not found

意思是unixODBC中的bin文件是32位的，在Ubuntu下执行不了，不知其他人是怎么通过的，是不是Ubuntu安装支持32位的库就可以解决？

是这个吗？

是没有装odbc插件，感谢

目前可以显示画面，就是色彩不对，STM32单片机显示又是正常的

注释tcon0，fb0就没了

按照 https://www.cnblogs.com/listenscience/p/13619930.html 方法，出现了两个fb，分别是fb0和fb1，fb1才是st7789，文件树注释掉了panel那一段，重新烧录还是有fb0，不知道怎么删掉fb0，只留一个ST7789

wifi模块是ESP8266吗？

修改lv_font目录下lv_font。mk，后面加+=myFont.c编译通过

应该不是改Makefile，
不好意思，我没问对问题。应该是lv_conf.h应该怎么修改才能使用自定义的字库？

只把myFont.c加入lv_font目录和声明LV_FONT_DECLARE(myFont);不够吧？
