@awwwwa 找到问题了，核心电压原本是0.9v给到0.95就正常了

@whycanservice2 大佬我最近打完板子了，焊接完成后可以识别到usb了，我想玩这个的d1s 能给个学习路线吗，现在没头绪

发现OpenWRT已经内置了Orange Pi PC 支持了。

大佬牛，跟着复现一下。然后去交作业。

@bigfly 那个是电感，这个开发板没有板载麦克风

你要注意一下，这儿的 spi 速度值并不是可以随便设置的！ 因為 cpu 除频后会配不上！ 会跳到默认的 10Mhz 的速度。

建议你可以在 .... spi 中，加打印，看看你那值是否可以通过！

/driver/spi/spi-sunxi.c 中

/* set spi clock */ static void spi_set_clk(u32 spi_clk, u32 ahb_clk, struct sunxi_spi *sspi) { u32 spi_test = 100000000; u32 get_spi; dprintk(DEBUG_INFO, "set spi clock %d, mclk %d\n", spi_clk, ahb_clk); for(spi_test = 50000000; spi_test >= 20000000; spi_test -= 1000000) { clk_set_rate(sspi->mclk, spi_test); get_spi = clk_get_rate(sspi->mclk); printk("spi_test %d == get %d \n", spi_test, get_spi); }

像我以 100Mhz 到 80Mhz ， 每 1Mhz 做变化！

就可以知道，有一些值设置是不行的！ 要特定值才行！

一、修改频率方法

首先通过cboot0命令，跳转到boot0的代码中，路径为：
${root_dir}/lichee/brandy-2.0/spl/

找到lspsram的代码，路径为：
${root_dir}/lichee/brandy-2.0/spl/drivers/psram

修改头文件，将200M的宏打开，修改如下：

vi hal_psramctrl.h diff --git a/drivers/psram/hal_psramctrl.h b/drivers/psram/hal_psramctrl.h index a552a0e..114e330 100644 --- a/drivers/psram/hal_psramctrl.h +++ b/drivers/psram/hal_psramctrl.h @@ -39,7 +39,7 @@ * definition CONFIG_PSRAM_200M. */ -// #define CONFIG_PSRAM_200M +#define CONFIG_PSRAM_200M /* CLK CTRL MODULE */ #define BUS_CLK_GATING_CTRL0 0x4003c004

然后重新编译boot0，就可以让lspsram初始化为200M了。

mboot0 && pack

##二、根据log查看频率

根据boot0的系统log，可以查看到当前lspsram加载的频率，如下图所示：

downloadFileByUrl (2).png

psram chip APS64 init ok!, freq 192000000

证明当前加载的是lspsram型号为APS64，频率为192MHz。若将频率切换成200MHz，此处的打印就会改成"freq 200000000"。

@lvjun0728 你好，你在t113上使用的ncm方式的操作方法能分享一下吗

@haaland DWT组件全称是Data Watchpoint and Trace，M33处理器中有硬件支持，开发者可以使用它提供的watchpoint比较器以及周期计数器进行代码调试、性能分析等工作。

可以借助DWT的计数器获取处理器的时间信息，计数器的精度是（1 / cpu频率）：
（1）使能DWT模块并清0计数器；
（2）使能计数器；
（3）读取计数器值。

统计短代码块耗时示例：

#define DWT_CR *(volatile uint32_t *)0xE0001000 #define DWT_CYCCNT *(volatile uint32_t *)0xE0001004 #define DEM_CR *(volatile uint32_t *)0xE000EDFC #define DEM_CR_TRCENA (1 << 24) #define DWT_CR_CYCCNTENA (1 << 0) int dwt_init(void) { DEM_CR |= (uint32_t)DEM_CR_TRCENA; # 使能DWT追踪 DWT_CYCCNT = (uint32_t)0u; # 计数器清0 DWT_CR |= (uint32_t)DWT_CR_CYCCNTENA; # 使能计数器 return 0; } void main(void) { uint32_t ticks; uint32_t told,tnow; uint32_t cpu_freq = get_cpu_freq(); float time_ms; dwt_init(); tcnt = 0; told = (uint32_t)DWT_CYCCNT; 代码块 tnow = (uint32_t)DWT_CYCCNT; /* 计算间隔 */ if(tnow > told) tcnt += tnow - told; else tcnt += UINT32_MAX - told + tnow; time_ms = (float)(tcnt) / (cpufreq / 1000) # 假设经过的时间以ms为单位 }

实现延迟：
根据计算时间的公式，也可以根据期望时间换算出所需要的tcnt计数值，在while中循环读取计数器值直至其增加的计数值达到tcnt，以实现延迟。

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。

if (!list_empty(&pVencPara->mInBuf_Q.mIdleList)) { I0101 06:57:02.989159 1255 sample_venc.c:1145] <readInFrameThread> idle list empty!! I0101 06:57:02.989212 1255 sample_venc.c:1063] <readInFrameThread> ready list empty I0101 06:57:02.989262 1255 sample_venc.c:1145] <readInFrameThread> idle list empty!! I0101 06:57:02.989313 1255 sample_venc.c:1063] <readInFrameThread> ready list empty I0101 06:57:02.989448 1255 sample_venc.c:1145] <readInFrameThread> idle list empty!!

jlt35031c是比较少见的小端屏，但是大部分的SPI屏都是大端屏，所以用jlt35031c时，需要修改sys_config.fex里面的配置项lcd_rgb_order为9.

unsigned char color[4] = {0xff,0x0,0xff,0x0};

这个数组决定颜色，颜色顺序是R（红） G（绿） B（蓝） A（亮度）。

所以红色 + 蓝色，应该是紫色

但是这里由于使用的是SPI接口驱动这个屏幕，并不支持lcd_rgb_order的参数配置。所以在屏幕初始化的时候通过写寄存器配置为对应的接口以支持LVGL的正确显示输出。但是测试命令可能会出现反色的情况。

自己编译出来的烧录之后启动是这样，用开发手册上现成编译好的镜像烧录可以正常使用，手册上面编译出来烧录运行的截图也是和这个一样，论坛也说v853是默认开启的wifi选项的，还需要额外镜像哪些内核配置和openwrt配置吗

@newcastle 这个是音频那边的问题，可以把audiosystem关闭下先调试屏

R128支持nor-flash，代码可以放在xip运行，保存在xip的方法可以看到对应工程下的xip.lds.S。

或者可以将dsp占用的8Mhpsram转移部分给C906使用，在dsp代码量不大的情况下，例如把dsp的内存裁剪到4M后，参照以下步骤把4M hpsram分给C906

打开C906的menuconfig
1）使能CONFIG_HEAP_MULTIPLE宏，令C906可以同时使用多个内存堆；
2）使能CONFIG_DEFAULT_LPSRAM_HEAP，CONFIG_LPSRAM_HEAP 宏，配置默认内存堆为lpsram；
3）使能CONFIG_LPSRAM_HEAP_DYNAMIC_ADDR宏，意思是lpsram的内存是动态分布的；
4）配置CONFIG_LPSRAM_HEAP_SIZE的大小是0x600000，因为前面2M给M33使用，所以剩下6M；
5）使能CONFIG_HPSRAM_HEAP宏，使能HPSRAM
6）配置CONFIG_HPSRAM_HEAP_START_ADDR为0xc400000，0xc000000是Hpsram的开始地址，前面4M已经分配给dsp使用；
7）配置CONFIG_HPSRAM_HEAP_SIZE为0x400000，意思是可以用的hpsram大小是4M。

其中LPSRAM和HPSRAM的配置也可以考虑互换。

去m33核打开，参考这里https://r128.docs.aw-ol.com/r128/rtos_manual/#_5

@xjy_5 妈耶，原来是少了一句配置，现在搞定了

@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。

@edisondeng 没有测试过TVD1，测试过TVD0,
可以自己阅读下源码和dts的配置关系，改一下看是否能用。

修复好之后的显示效果，一切正常了

你好，问题解决了吗？

请问，这个问题解决了吗？
有大神解决了该问题吗？

尝试将android工具getevent移植到linux中，可以成功查看电阻屏的反馈速度。
参考了 https://www.cnblogs.com/liangliangge/p/12921889.html 中的办法
工具的源码路径为：android/system/core/toolbox/getevent.c
其中源码中getevent.c文件中内容有修改
由于头文件input.h-labels.h生成过程中涉及权限问题，直接新建了input.h-labels.h文件并复制黏贴了参考链接中的内容
Makefile文件参考了 lichee/buildroot-201611/target/user_rootfs_apps/cmd/subs 下的工程里的Makefile

用getevent -lrt命令输出时间戳、上报速率等，要计算事件之间的时间间隔，我们可以取两个连续事件的时间戳（括号内的数值）并计算它们之间的差值。这个时间戳的单位不太清楚。

@zznzzn 这个是由于编译过程需要从github下载东西，但您的网络有问题，所以编译失败，可以更换源试试。

@newcastle 可以尝试关闭在线模式

你好，请问问题解决了吗，我这也遇到类似的问题

你好，我也遇到了相同的问题。您最后怎么解决的

您好，你最后能从自建分区启动吗

屏参改一下

lcd_driver_name = "default_lcd" lcd_backlight = 150 lcd_if = 0 lcd_x = 1024 lcd_y = 600 lcd_width = 150 lcd_height = 94 lcd_rb_swap = 0 lcd_dclk_freq = 48 lcd_pwm_used = 1 lcd_pwm_ch = 7 lcd_pwm_freq = 500000 lcd_pwm_pol = 1 lcd_hbp = 160 lcd_ht = 1344 lcd_hspw = 20 lcd_vbp = 20 lcd_vt = 635 lcd_vspw = 3 lcd_lvds_if = 0 lcd_lvds_colordepth = 1 lcd_lvds_mode = 0 lcd_frm = 0 lcd_io_phase = 0x0000 lcd_gamma_en = 0 lcd_bright_curve_en = 0 lcd_cmap_en = 0

@mysteryli 可以新建docker 容器时，使用当前用户权限

@q1215200171 这个有用

@cywlw 抱歉，这个没调好就没保存了

@awwwwa 好的，谢谢。问题已解决

是否可以创建一路VirChn，同时绑定三路编码(MP4+jpeg+rtsp)，然后在VI上叠Qt的OSD？是OSD效率高，还是采用非绑定模式，先GetCSIFrame后做G2D处理，再send到三路编码的效率高？

@huangyuhan
systemctl不工作

@sunxi source后 mkmpp，你的环境变量没有导入，不能直接make mk文件

鸿蒙，没玩过。一直用的freertos

可以访问：https://github.com/DongshanPI/buildroot_100ask_t113-pro/blob/master/docs/07-Buildroot-SDK_DevelopmentGuide.md

使用buildroot-SDK编译构建系统 简介 此套构建系统基于全志T113-S3芯片，适配了buildroot 2022lts主线版本，兼容了百问网的项目课程以及相关组件，真正做到了低耦合，高可用，使用不同的buildroot external tree规格，讲不同的项目 不同的组件分别管理，来实现更容易上手 也更容易学习理解。 安装必要依赖包 ubuntu-18.04

运行环境配置： 此系统基于ubuntu18.04进行验证，在之前的基础之上还需要安装以下必要依赖

book@100ask:~$ sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip lib32z1 lib32z1-dev lib32stdc++6 libstdc++6 libncurses-dev u-boot-tools -y

参考

bb10ced5b443c6b7af2cf52871b987406faa37b9_2_690x358.png

修改编译指定的配置文件

book@100ask:~/buildroot-100ask_t113-pro/buildroot$ make BR2_EXTERNAL="../br2t113pro ../br2lvgl ../br2qt5" 100ask_t113-pro_sdcard_qt5_defconfig book@100ask:~/buildroot-100ask_t113-pro/buildroot$ make V=1

最终编译生成一个 sdcard.img 烧录至开发板内 启动，就包含了 qt lib库等，同时QT 环境 也会在 buildroot源码根目录下 的 output/host内。

在reboot老化的时候，关闭休眠

从kernel的log来看，安卓层先发起了reboot，内核也收到reboot的消息

#1[2023-07-11,16:56:45][ 41.176369][ T164] init: Received sys.powerctl=‘reboot,’ from pid: 490 (system_server) [2023-07-11,16:56:45][ 41.185428][ T164] init: sys.powerctl: do_shutdown: 0 IsShuttingDown: 0

同时从安卓的log来看，安卓层也会有息屏关机的动作。

所以这个时候是刚好在reboot的过程中，安卓执行休眠打断了reboot并且休眠成功。一般建议做reboot老化的时候要关掉休眠，之前也出过类似现象

可以看 《Linux_Display_开发指南.pdf》 不过这个也没有设备树的配置描述，更多是源码描述

@yuzukitsuru T113 没有这个选项 要怎么设置啊

执行 muboot && mboot
