对于文件 bsp/configs/linux-5.4-ansc/sun300iw1p1.dtsi
明明使用了SPI0连接norflash，为什么spi0还是status = "disabled";呢？
如果我要用到spi1驱动LCD，是都要把SPI1改为status = "okay";呢？

V821平台修改后确实OK了
但是V851S平台还要继续调查

@awwwwa 在 V821平台如何修改文件系统分区大小 中说：

https://docs.aw-ol.com/docs/soc/v821/software/configure#分区表

这个是整个文件系统的，不是文件系统内的分区啊

企鹅群788138909

如下图
我想将/tmp的大小减小，将/的大小变大，将UDISK的大小也减小
V821+PY32Q128

@momoyu 在 wifi命令不打印任何东西 中说：

@mysteryli 我看你的截图，应该是adb里操作的？
在 ADB 输入的 WIFI 指令操作会打印到串口，你直接用串口操作就可以了。
或者按照下面的链接去修改：
https://docs.aw-ol.com/docs/soc/v821/faq/v821_system#adb中输入-wifi-指令adb没有输出

好的，但是V851S平台也是如此，用串口也没输出，这个是怎么回事呢

目前已经可以启动系统，ADB正常，sensor正常，其他外设还在调试中
个人能力有限，有感兴趣的联系我，做了27片
企鹅929916200
由于是晕哥赞助的板子，因此送板子的策略需要我和他商量下
空板也有很多，这个可以免费送，自己出邮费即可，我邮寄也行，全国都是5-6块
还有就是只贴了大部分原件，个别原件需要手工补焊，由于我的焊工确实不怎么样，因此我不管焊接哈

如题，教程如下

但是我的不打印任何东西，也修改了日志级别，我有两个平台，V851S和V821丢都是这样，感觉是哪里配置的不对，请大佬指点。。

如何添加iw命令呢？

有大佬遇到过嘛

哪位大佬知道怎么回事啊 声音文件是没问题的

@awwwwa 在 是否能看出来无法启动的原因是什么，添加了V851S的补丁后就无法启动了 中说：

已经启动了，console=tty0 显示在屏幕上了吧

可以无法进入终端呢，是终端显示到屏幕上了嘛，而且屏幕也没有显示
下一步不知道怎么排查了。。
要把终端重定向到串口嘛

板子是V851S自己设计的板子
加了一下3.1寸mipi屏的驱动后，就无法启动文件系统了，请问大佬什么原因

V851S这两个引脚到底是1.5v还是1.8v呢，看手册说都行啊
实测1.5V的板子一切正常，1.8V的也一切正常但是一用ISP就死机，不知道有关系没，毕竟ISP也要用DRAM

V851S这两个引脚到底是1.5v还是1.8v呢，看手册说都行啊
而且还有一个DRAM供电引脚都是1.8V
实测1.5V的板子一切正常，1.8V的也一切正常但是一用ISP就死机，不知道有关系没，毕竟ISP也要用DRAM

目前在调试ISP，遇到下面问题，大佬提示说可能是文件系统问题，但是完全摸不到头脑应该如何查找。
看起来XZ命令失败了。。。
已经确定的是文件系统不是只读的，可以正常在根目录创建文件和读取

我是自己的V851S板子并使用东山开发板的docker SDK，移植了opencv后发现调用ISP报错了，不知道是不是缺少了isp0_1920_1088_30_0_ctx_saved.bin这个文件，如下是报错内容和串口输出

开发环境使用的是docker
芯片是V851S，之前能正常编译SDK和下载镜像，后来合并了一下小正太大佬的opencv，发下能编译和生成镜像，但是下载的时候下载失败，串口输出如下，应该怎么排查呢

@whycanservice2
老哥 问两个问题
1.你的PH0做pwm调好了吗
2.屏幕会显示启动log嘛

但是patch中修改的文件，例如cap_v4l.cpp等
我只能在out中找到他们

看了大佬的博客
https://gloomyghost.com/live/20240121.aspx
想加入opencv支持，但是遇到问题就是大佬说要改下代码中opencv的视频捕获类型，但是不知道具体是改哪些代码，不知道是否有大佬可指点一二

看到大佬帖子 有人试过吗

成功了请踢我一下

@null037 在 V853/V851s 增加 OpenCV, FFmpeg 编译包 中说：

@yuzukitsuru 大佬，将opencv已经打包进去，编译生成新镜像后，测试了一下opencv-sample，发现opencv无法打开GC2053的video0节点，然后我外接一个USB摄像头就，修改程序读取的节点可以程序就正常读取video1节点。

下面是读取默认GC2053 video0节点时的报错

root@TinaLinux:/# opencv-camera 
VIDEOIO ERROR: V4L2: Unable to c[  702.464977] [VIN_ERR]video0 has already stream off

R: V4L: can't open camera by index 0
/dev/video0 does not support memory mapping

这个GC2053节点使用camerademo可以正常拍照测试。

当我外接一个usb摄像头，修改代码读取video1节点时，就可正常显示

root@TinaLinux:/# ls /dev/video*

请问为什么GC2053节点无法被opencv程序读取呢？

@null037
请问问题解决了么？ 我和你遇到同样的问题。

@yuzukitsuru
但是adb上看来会死掉（是整个linux挂掉adb断开，需要重新上电才行），回头我看一眼串口输出，

运行的时候好像遇到了问题

@qinlinbin 在 T113-s3 CAN linux 下已调通 中说：

大佬，想问一下，你有测试过80k以下波特率的吗？我试了一下，会报这个错误。
ip link set can0 type can bitrate 50000
sunxi_can 2504000.can can0: bitrate error 8589934.5% too high。你有遇到过吗？

看起来是驱动不支持这么低波特率？

rt
想DIY一些汽车诊断相关的东西要用到FD

好像不行

@awwwwa
可以了 谢谢大佬

按照手册打开的时候输出如下，请问大家可能是什么原因，还有就是这个是用作SPI-TFT的背光用，不想每次开机后打开，想启动初始化pwm时候设置后占空比，怎么修改呢，要魔改驱动嘛
sh: write error: No such device
报错如下

设备树如下

勾选了之后编译SDK报错，可能是什么原因呢

@awwwwa 在 问下大家camerademo抓的是原图还是ISP调色过的图呢 中说：

camerademo 支持抓ISP后的图

勾选使用 VIN ISP 驱动即可

使用 ISP  camerademo NV21 1920 1080 20 bmp /tmp 2

直接抓RAW：camerademo BGGR10 1920 1080 20 bmp /tmp 2

好的，谢谢大佬

我是想抓ISP调色过的图

请问下大家 V851S移植了一块SPI屏幕并生成/dev/fb0 目前都正常，想把linux启动日志打印到上面，要怎么修改呢
记得之前V3S可以修改SD卡中的bootargs，现在用的nand不会了

@awwwwa
先谢过老哥
不过试过了 还是不行
这个是GPT的答案嘛哈哈

@awwwwa 在 编译全志V851s的SDK遇到如下问题，有没有同样的 中说：

看起来是系统perl环境问题，请问是什么系统

ubuntu系统20.04
那要怎么解决呢

谢谢，感谢分享，我是为了LV2，加油

@awwwwa 在 YUVToBMP函数运行时间长问题 中说：

@mysteryli 正常，这个函数没有任何优化只是实现了功能，可以使用G2D转换YUV2RGB

有示例啥的嘛
怎么用G2D代替软件实现

RT
V851S下这个函数转换一个1920*1080的图片大概需要100ms左右，这是正常的嘛

另外这个转换是不是可以用G2D硬件完成，会快一些？

@zheng1 在 V851S tina linux ov5647 驱动程序没有 dmesg 中说：

@kanken6174 camerademo抓图正常吗？如果camerademo抓图正常，那就是Tiger ISP的配置问题了。先确保camerademo能抓到正确的图

我的平台camerademo能抓图了
Tiger ISP怎么调呢

V851S的SDK也在这里下载吗？

fbviewer能自动缩放图片嘛

@awwwwa 在 camerademo.c修改后编译打包的camerademo不变 中说：

请问有人遇到过嘛，Tina
by the way
怎么单独编译camerademo

换sensor都需要修改什么呢

@vincent1 在 V853适配FFMPEG网络推流的摄像头有推荐吗？ 中说：

@mysteryli eye-mpp这个包是要做什么才能获取的吗？我的sdk里面是没有eye-mpp这个包得

不会的，官网下的都有的啊

我记得eye-mpp里面有个RTSP的DEMO，如果实时性要求不高可以试试
不过我没跑起来那个Demo，而且有几个网友也没有跑起来，不知道官方是否会去解决
你如果跑起来后，FFmpeg可以推流RTSP

@dingxmhan 楼主解决了吗？遇到同样的问题

我的也是，我也试了VIRVI2VENC也不行
vi_g2d可以

RT，全志的mpp的demo会产生NV21格式的原始图片，怎么查看这些图片呢
我的板子只有/dev/fb0,没有/dev/disp
所以没法显示

回复: v851s g2d 模块 sample 深究

看到G2D的例程输出到/dev/disp，
我换了屏幕使用fbtft，生成了FB0，怎么才能让这个mpp例程输出到fb0呢？

问题解决，结贴

@whycan 在 为什么我的板子复位重启后按上键，没有历史命令了 中说：

@mysteryli

tina默认没有开启cmd history功能，

make menuconfig 搜索 HIST，开启对应的设置，然后重新编译打包烧录，应该就可以了。

好用 还愿

如果改为按下再松开 就是下面这种

有没有哪位大佬手头刚好有evtest，且有触摸的，帮忙看下输出对不对

@misay 在 v853如何调用摄像头并用于yolov3进行目标检测 中说：

目前做好了火焰检测的相关内容，push照片可以推理检测，现在想调用摄像头并存储图像再检测，不知道该咋继续了，来个大佬救救

当然是改代码了，基于SDK里yolov3的demo改成从摄像头拿图

@gaowei15537316965 在 我这个校准没反应，有没有大佬知道的，f1c100s 中说：

@mysteryli 这个有啥解决方法吗，或者就是有啥可以去看的方向吗

我和你平台不同 触摸也不同 我是电容屏，tina环境，估计没啥参考价值

我的问题和你这个还不太一样，我的问题是光标可以受控制，却无法按下，看你这个evtest的结果，只是上报了位置，看起来也没按下，跟进你后面进度

@lingzhi12321 在 V853怎么交叉编译OpenCV 中说：

@whycan V853怎样启动这个界面？make menuconfig启动的是openwrt configuration界面

没用buildroot的文件系统，用的openwrt的文件系统 应该没这个界面吧

触摸移动鼠标可以跟着移动，但是点击却没反应，调试发现ABS_X和ABS_Y事件都有，BTN_TOUCH事件却没有上报到/dev/input/event0
求大佬帮忙分析
驱动中上报关键代码如下

	input_report_abs(ts_data->input_dev,ABS_X, x);
	input_report_abs(ts_data->input_dev,ABS_Y, y);
		printk("key up\r\n");
	input_report_key(ts_data->input_dev,BTN_TOUCH,1);
	input_sync(ts_data->input_dev);

如题，正常不是应该有个.history嘛

如题 平台是V851S，目前是mkernel和pack后生成img用phonesuit刷进去，如果我修改了一些驱动，文件系统中的文件还想保留，怎么办呢

@whycanservice 在 求助，触摸事件上报导致内核崩溃 中说：

直接用root用户你就不怕我再脚本里塞个 rm -rf /*

@whycan
但是这个是说传输未完成
是因为我没接任何IIC设备，主机收不到ACK，所以认为传输未完成是吧
那我直接去内核里吧打印的地方注释了，是不是也行

SDK是东山pi的那个docker，在系统中执行i2cdetece -y 3
就会出现如下情况

@whycan
发现了两个gpio.h不知道什么区别，用的哪个 arch下的那个好像有东西

@whycan
kernel/linux-4.9/include/linux/gpio.h
我想应该不是调用的这个函数，是我查找的方式不对
IO在内核驱动调用阿志肯定得验证过的

一路跟踪GPIO的设置函数，最后发现是个空函数，我哪里搞错了呢？
看了V85X的SDK和D1S的SDK，发现都是这样的

@h2631436132 在 没有make命令怎么make kernel_menuconfig 中说：

@whycanservice 那这一步怎么实现

这是串口信息

虚拟机里也弄不了

我只能说 严格按照手册操作哈

tips：另外还有一个线索就是之前有一块MIPI的屏幕，初始化代码也是正确的，同样无法点亮，大佬docker里面的代码可以点亮，由于内核代码量较大，实在无法比较查分，仅对比了Driver文件夹和设备树，发现是相同的

回复: 使用 LicheeRV 86 Panel 与 Tina BSP 实现 RGB 与 SPI 双屏显示
参照大佬的这个博客修改了代码，无法进入初始化函数，是什么原因呢

怎么把yolov3的demo编译进镜像中呢？

@yelong98 SDK好像适配的都是MIPI接口的 DVP速度跟不上吧

@xiaowenge
一样吧 V851S想用RGMII也没法输出LCD了
