可以研究一下xboot

@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。

@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😵

第一种方法，使用cklink/xfel下载到sram内运行，下载后执行sram地址即可，sram只有32k注意程序大小不要超过

第二种方法，使用cklink/xfel初始化dram，下载到dram内运行。dram较大

解决了，对比了LicheeRV_Tina_dock_hdmi_8723ds.img 这个镜像的log， 然后根据关键字在源码里面翻了一遍，做了几处修改。

修改设备树

修改配置文件

@chdeng1 可以参考D1 SDK下面的d1_nezha_min-tina方案进行裁剪，逐步添加上自己需要用到的软件包既可，主要还是针对于uboot部分和rootfs部分不需要的软件包进行裁剪

@whycan 问题已经解决，感谢，硬件排线接触不好

@yuwei 看看有没有这个 package/allwinner/tina_multimedia_demo/encodertest

@wyljkl 实际上就是reboot efex无效导致的，换上面介绍的方式操作吧

可以直接取代sbi的位置

@emperg VE还在解码，可其他模块把buf释放了？应该在解码的回调函数才可以释放buf吧

@whycanservice 三剋有

@how0723 @whycan

@whycan
f50760bb-6fcc-4b8c-8cb5-65c2f872e968-image.png

sunxifb_init(rotated) 这个函数定义在lvgl,开机校准这个界面不能用这个函数，还是没法旋转这个校准界面，

@whycan webwxgetmsgimg.jpg

@lyscut 要在哪里设置呢？

@dyd2022 请问一下，您uboot可以显示logo吗？ 我内核可以驱动lcd 并显示了，移植到uboot,设备树设置了跟内核一样，图片也换了相同分辨率的，但是uboot还是没有显示logo,大概是什么问题呢?大佬可以贴下您uboot 的设备树文件吗？

@whycan 哈哈大哥用的就是你开源的那个板子（自己改造了一下），再请教你一个问题行吗？烧录不对会不会和固件有关系，用SD卡烧录的方法，直接识别不到SD存在。

相同板子，处理器是D1s, 继续测试RTL8189FS，却很稳定，没有出现问题

@gsd_zcm 这个是d1的空间不够，在menuconfig的base system里配置下

@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。

@chengwei_peng 谢谢前辈，讲解的好详细

@gongweijie -J1看看

@xiaowenge 这个问题麻烦您了，帮忙看看

@wyljkl
我找到问题了，这个引脚的配置不能这样配置，改成这样就可以了，感谢各位大佬！

@gsd_zcm 在 希望全志的大神出一个D1s tina APP怎么引用其他库文件的教程 中说：

@chengwei_peng 谢谢前辈，讲解的好详细，按照前辈的方法，代码可以正常编译了，下面是我的makefile，可能有些地方不够好，伙伴们可以参考下。

注释好详细，感谢分享！

@chengwei_peng 好的，谢谢前辈，我去看看

@theoldfisherman 在 添加库 中说：

@jr_online 谢谢你，又多了一个解决方法

得谢谢大佬@WhycanService

@yuzukitsuru

7930b498-20a8-4988-ad72-37e483f1a0b1-image.png

发现2/5/6 没有上拉.

@gsd_zcm 问题解决，需要在顶层文件夹先
source build/envsetup.sh
lunch
最后在make menuconfig

这个问题是openssl版本问题，因为我不是按照建议的ubuntu14.04而是wsl2 ubuntu20.04环境编译的，所以遇到的这个问题可能大家一般不会遇到，后来各种搜索资料解决了，这里说一下方法了结这个问题。
查看openssl版本，通过apt降级到1.1.0版本（SDK里是1.1.0.i），之后手动删除out目录下之前openssl的编译输出，然后重新编译就好了。

@ming899 官方的视频教程提到tina sdk uboot 开启lcd的显示，内核就不走开屏流程了，进内核后可以休眠唤醒打开屏

恭喜恭喜👏 👏

@taoyang 在 D1 两个wdog 的作用是一样的吗？ 中说：

wdog0 和wdog1 都是不喂狗时触发硬件reset 信号吗？

会，都可以通过寄存器配置决定是否产生中断活复位系统。

@geniusgogo melis默认支持的屏幕是什么屏幕，还有触摸支持是啥芯片。刚看到这个代码，还没发现这部分~~

期待更多移植信息，和板子图片😁

@xiaogcc23333 计划这样，贴个SD NAND做数据盘

rm red.bin -rf && while [ 1 ]; do echo -n -e "\x00\x00\xff\xff" >> red.bin; done; rm blue.bin -rf && while [ 1 ]; do echo -n -e "\xff\x00\x00\xff" >> blue.bin; done; rm green.bin -rf && while [ 1 ]; do echo -n -e "\x00\xff\x00\xff" >> green.bin; done;

tina 的玩法不同，不会生成这个文件。

以上是 T113-S3从SDC0 TF卡启动日志。

更新一下修复方案：

问题发生在u-boot-2018/common/board_f.c文件的reserve_board()函数的memset()进行写内存时；
原512M内存的代码在U-Boot运行会出现错误，是由于opensbi的PMP设置中，0xbfxxxxxx地址没有访问权限，故触发异常错误

支持D1 2G内存的主要patch在opensbi的sunxi_platform.c文件sunxi_pmp_region_info()函数中的PMP设置；

正常运行的opensbi：

检查 uboot-board.dts 里面关于 sdc0的引脚配置。

@anruliu 就直接x和y相关的值直接交换一下

@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

@tp055 libssl通过换源解决了，但是ncurses还没有解决

@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。

系统配置/应用打包这两个

@houxiaoni 执行tplaydemo，然后在敲命令，然后quit退不出来，程序死在了TPlayerDestroy了，我也是无语了！

d1s没有mipi csi，只有mipi csi的文档

是，rootfs挂了

@yuzukitsuru
大神你好，我这边也是无法打开debugfs。使用的是D1s芯片。

kernel_menuconfig中尝试打开如下开关：
Kernel hacking > Compile-time checks and compiler options > Debug Filesystem
没有/sys/kernel/debug目录

menuconfig中尝试着再打开如下开关也没有用：
Utilities > Filesystem > debugfs

搜索debugfs，基本上都是和驱动相关的选项。
实在不知道还要打开什么开关了，请大神指教。多谢多谢。

@allwinnertech 666

@yunchawaishi 命令输入就行了

@cube_work 配置USB HID要在input里打开input设备，HID是一个较低层的接口，上层还需要input的支持，或者直接打开USB KEYBOARD这样的，直接提过支持

同刚入门,想问下用这种直接终端操作对比官方的pinctrl操作是否响应速度有不同?
我是想生成脉冲控制步进电机的,如果有区别的话用pinctrl是不是更快一些?
但是找不到例子都不知道头文件该调什么:(

@whycan 在 原生Openwrt支持 中说：

不管能不能成功，先谢谢大佬。

@whycan 在 T113能跑QT吗？ 中说：

@jr_online

【T113-S3开发板视频解码、LVGL、Qt测试-哔哩哔哩】 https://b23.tv/LM5eCu6

好滴，谢谢大佬

@waterworld 可以了，谢谢👍

@huangjun-zopudt 打开通路啊，类似这样的

amixer -D hw:audiocodec cset numid=32 1 && \ amixer -D hw:audiocodec cset numid=16 30 && \ amixer -D hw:audiocodec cset numid=18 0 && \ amixer -D hw:audiocodec cset numid=19 0

@captain 我已经解决这个问题了，在menuconfig里不止要把kernel module/wireless driver里的换成xr829，还需要进到firmware里把xr829 with 40m sdd这个选项关掉

请问楼主成功了吗,一样的问题😢

@lansecd 晶振在作怪，跳线成无源晶振直接就刷进去了。。。。。。。。。。。。。。。。

@nikola 分区boot-resource的大小改了之后还是8M大小

@yuzukitsuru 您好!您能把您的代码发给我做个参考吗？谢谢您了

@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，😂

请问解决了吗？我也想试一下d1的安全启动。
