请问有关于wdr模式的底层框架图吗，我这边需要在支持该功能，在论坛上找了挺久也没有找到相关资料，，求帮助~~

@yuzukitsuru 十分感谢！！

buildroot请使用ubuntu14.04

@xiaowenge 谢谢大佬😊

https://bbs.aw-ol.com/topic/1080/在tinav2-2-d1s上面搞lvgl8去调用g2d旋转让lvgl8的软件旋转再见?_=1646643614443

可以参考这个帖子

@fresird Windows 自带有的。

@chinazhangdj 在 Tina linux spi lcd无法刷屏 中说：
大佬有调试通过了吗？能否请教一下怎么调

大大单片机（（（

@yuzukitsuru 请问有具体的配置方法吗，dts需要修改什么地方去指定不？我看vinc1_isp_tx_ch的通道指定只是适用于wdr这些多路输出。

您好，你最后能从自建分区启动吗

@chinazhangdj 我试试，感谢

@yuzukitsuru 谢谢大佬的解答

@sunchipv 在 V853的QT被random进程阻塞了 中说：

haveged -w 1024 -v 1

可以了，谢谢。我将这个命令写到 profile 里面，开机后熵池可以到2000+，可以很快的启动我的QT了。

我也找到了rgnd工具，可以执行rngd -r /dev/urandom -o /dev/random，熵值可以到4000+

@zznzzn 我目前这样写的，还是写入失败，/etc/resolv.conf里面没有东西，会不会是权限问题？ppdd那个正常
1663836218094.png

@yuzukitsuru 开启了，图像内部的一些轮廓位置一直抖动，好奇怪，其他文件又是正常的

@gonboy 现在芒果的店里应该不卖了，到闲鱼上找找应该有

@yuzukitsuru 怎么样才可以跳过啊？为什么要跳过？ 我现在就是需要在RISC-V上的perf链接linunwind这个库

楼主，T113 RTT SMP跑起来了吗，方便共享下资料不

@icpachong 已编辑，感谢老哥分享

@lk664243752 已解決 export FORCE_UNSAFE_CONFIGURE=1或

@waterworld

find . -name "*.o" |xargs rm

@yuzukitsuru 这个就很尴尬了

@whycan 感谢晕哥，串口杜邦线出问题了，搞了好几天，最后发现用杜邦线短接Ch340不能回读。。。。

@whycan 好的谢谢！

@whycan 好的 谢谢大佬

@dream 按住UBOOT再按RESET就可以了

@yuzukitsuru 好的，感谢

@yuzukitsuru 确实是没配置串口，我改硬件了，只有BOOT0那里修改了，内核设备树那里没改，😂

你好 请问问题解决了吗，需要相同情况

@yelong98 谢谢指点，已经解决了。

@yuzukitsuru 在 环境变量中关于ubifs、nand_root的疑问 中说：

第一个使用ubifs作为fs，第二个使用sqfs作为fs，ubi提供操作接口，一般都用第二种

所以第一种的前提是必须构建好ubifs才可以成功启动？

以及我若是需要使用第二种方式来使用ubi，两者在配置上还存在哪一部分的差异呢🤠 🤠 🤠

V853开发板工厂测试固件20220630.img 是测试使用的，root命令行被测试工具占用了

@dream 因为这是教程

@sdlmd2020
可以用硬件dsp实现

@inomec 强刷呀。找 boot 或者 fel 的按键，按下再复位或者重上电。

@whycan
试了试扩大roofs.fex大小，换了张64G的SD卡，重新烧录，好像还是不行。不过其他的demo，比如lenet，是不会出现这个问题的。只有YOLOV3 会有这个问题。

@yuzukitsuru 都烧不进去，是不是要改什么配置？

@aozima

给大佬点赞，改成10K之后，LED没那么刺眼了，与全志官方的V853开发板通讯也正常了．

@yixiuge 在 开发板报错 中说：

fsck.ext4 /dev/mmcblk0p7

root@inomec:/# fsck.ext4 /dev/mmcblk0p7 e2fsck 1.42.12 (29-Aug-2014) /dev/mmcblk0p7 is mounted. e2fsck: Cannot continue, aborting.

@yuzukitsuru 我用的buildroot ，之前用openWrt 编译后启动不了，多谢，我再试试

@ottojiang 在 Ubuntu官方又支持了一款仅有硬币大小的RISC-V SBC 中说：

我如果想修改内核添加驱动该怎么做呢

下载源码自己移植编译

@whycan 板子是在/lib下，实际构建时添加进去的，构建路径放在了/package/add-rootfs-demo/lib路径下。

@yuzukitsuru 我没有按照教程安装repo 才导致这个错误

你好，我修改时钟为50m后，发现twi工作不正常了，我应该怎么去修改。

@whycanservice 谢谢回复。
我已经在clk驱动中将module_platform_driver(clk_driver);
改成了
static int __init clk_init(void)
{
return platform_driver_register(&clk_driver);
}
arch_initcall(clk_init);//arch_initcall 等级为3
我通过kernel log 看，clk_driver 执行probe的时间确实有提前，但是有的使用module_init的驱动还是会在clk_driver之前执行probe。这让我感觉很疑惑。
我想过将驱动编译为module,但是clk涉及到很多功能，像是gpio，lcd，audio等，如果将上述的驱动都使用module，那就涉及到这些部分的驱动可能都需要编译成module，这样做是否会很奇怪。

@whycanservice 好的，谢谢大佬

我用t113编译点灯驱动也遇到了这个问题，楼主是怎么解决的

@whycanservice 感谢 确实发现设备了

@zhujun19790920 直接可以用，直接替换pin2pin的

@kelsey
搞定啦，flash上拉电阻补焊搞定。

@whycanservice 大佬，请问有没有摄像头的购买链接

@chengwei_peng 好的，谢谢前辈，我去看看

@xiaowenge 如何降低，mpp的功耗呢？

@whycanservice 很奏效，药到病除😊

可以的，但是那样裁剪后就没多少地方放东西了，6mb的kernel，1mb的rootfs太极限了

@whycanservice 在 【萌新】t113(tina)进入kernel时如何优先加载某个驱动？ 中说：

https://v853.docs.aw-ol.com/soft/soft_start/

可以手动配置wifi的执行顺序，wifi初始化完成后再开lvgl

好滴，谢谢大佬指点，我试一试。

Hi 您遇到的T113+RTL8189FS问题是必现的吗？目前情况如何？

@i_a_student 在 全志XR808芯片 如何设置AP模式默认IP地址、子网掩码、网关？ 中说：

@adsikl 就是在src/net/udhcp-0.9.8/dhcpd_cfg.h这里的，你修改后应该是有效的

鸿蒙系统的话用的事en2，试试改成en2试试？

@whycanservice 好的，多谢！

如果是镜像显示，这个接口支持不~~ 或是只能用g2d？

@whycanservice 哈喽，谢谢您的回复，我是想 win10 环境下编译的，需要如何配置编译环境呢？

主线使用的是drm驱动，建议参考kernel的doc

https://www.kernel.org/doc/html/latest/

@whycan 在 【萌新】Tina rtl8189fs 搜索wifi 中文名称乱码如何解决？ 中说：

538ba4b0-2975-4f10-9b2d-1bc02aa2b0c0-image.png

用 UTF-8 解码

晕哥，我通过c代码获取到的就是wifi名称的字符串数组：

BX_WIFI_24G_\xe6\xb5\x8b\xe8\xaf\x95\xe5\xa3\xb9\xe5\x8f\xb7

然后显示在lvgl的list组件上，就是乱码的。

但按以下方法就可以正常显示中文。

char *test = "BX_WIFI_24G_\xe6\xb5\x8b\xe8\xaf\x95\xe5\xa3\xb9\xe5\x8f\xb7"; printf("%s\n",test );

83dad9a7-ad08-47ac-b510-ede22945f279-image.png

是通过 "iw dev wlan0 scan | grep SSID: | awk '{print $2}'" 来获取wifi名称的，这样的话\x转义字符就变成字符串了，所以就直接显示乱码了，就不知道咋搞了😵

@whycanservice 时序参数问了屏幕厂家，也没有。相位调了一下没变化。之前是用stm32的fsmc驱动的。发现有rgb，所以看看用t113看能不能驱动。资料太少，还是放弃了。已买其它屏幕。谢谢了。

我现在在用MQ Pro + OV5640做项目，大佬是否愿意加我QQ？

@chengwei_peng 谢谢。 后面我试试， 现在使用ADB 将ko文件传到板子上调试了。

@whycanservice 问题解决了，原因是训练的权重文件迭代次数过高，不完善。需要降低

@whycan 谢谢，等疫情结束回到办公室再试吧，笔记本硬盘太小，编译不了

@q62865555 鸿蒙的没有OTA例程，只能下载freertos版本的才有OTA例程

@whycanservice 在 VFS: Cannot open root device "ubiblock0_4" or unknown-block(0,0): error -6 中说：

你好：

# flash CONFIG_SUNXI_SDMMC=y CONFIG_MMC=y CONFIG_SUNXI_FLASH=y CONFIG_SUNXI_NAND=y CONFIG_SUNXI_UBIFS=y CONFIG_SUNXI_COMM_NAND_V1=y CONFIG_SUNXI_SPINOR=y

@whycanservice 好的

getprop 里面并没有发现这个配置

这个配置在源代码里面的哪个位置啊? 我去看看源码

粉色版到货了哈哈哈，也太好看了吧

@yuzukitsuru 感谢回答！
如果在量化和预推理时循环多次的话，需要加入--iterations 6参数

@lingzijian
试一下直接管理员身份运行安装这个驱动，
全志USB烧录驱动20201229.zip

再不行的话下载全志的APST量产中心，里面也有一个USB驱动，把那个装上去试一下

@rain_tk 感谢大佬的回答

@whycanservice 大佬，非常感谢

@yixiuge buildroot是个啥

@jinxiangwzh 你好兄弟，能分享一下你的软件吗，我的版本太低想测的芯片没有

@whycan 已经解决 感谢回复~

@y97788 在 ubifs卷挂载问题 中说：

ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据，但是如何修改boot-resource.fex里bootlogo.bmp，或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件，然后再用上面命令来更新卷数据

你好，我也碰到了这个问题，请问你解决了吗

@whycan
x64-> x86-64 or a64
arm-> aarch64
ok ?
无所谓，用qemu运行也能用。

ae3f96f5-ab8c-4a55-a529-227bd0501808-image.png

请问一下这种情况要怎么解决

@whycan 谢谢晕哥，我重启一下虚拟机好了

@whycanservice 可以了 感谢回复，还有个问题，UVC要怎么设置两路，sample_uvcout只有一路预览，我改了run_org设置多一个uvc.usb1，运行的时候系统会崩溃

@hacker_exkc
请问 D1s 和 D1h 的 uboot 等通用吗?

@jinxiangwzh 有个通过 ADC 检测按键的 ADC，加颗上拉电阻。 不然只能修改 BOOT0

@whycan 就是按照v853的文档上操作的。
(1) ./build.sh config # 配置编译模式和项目文件
(2) ./build.sh # 编译
(3) ./build.sh pack # 打包

@whycan
感谢您分享信息。

有时A40i进入FEL模式，想修改一下，可惜了。

@whycan 晕哥我也遇到类似的问题了，检查了root.squash里面有/ pesduo_init文件。之前编译都是没问题的，存储用的GD SPINAND，编译OTA包总是出问题，make distclean后，再编译就有这个问题了。怎么查找问题，解决呀~

@leoneeyan 这个是正常报错，32bit下训练不过！没问题的！

@whycan 在 F1C200s类似正点原子驱动开发指南的资料？ 中说：

这个代码风格和正点原子接近: https://item.taobao.com/item.htm?id=589639202997 (没有PY关系, 三思再下手)

里面有教程吗？比如说某个驱动，有没有对应的教程文档，分析驱动原理与代码？谢谢晕哥
