@nlj_moon 检查系统是否存在大量占用CPU时间的程序，也可以通过MTR等工具进行链路测试来判断问题来源。

1.MTR基本信息
MTR（My traceroute）是几乎所有Linux发行版本预装的网络测试工具，此工具也有对应的Windows版本，名称为WinMTR。
MTR工具将ping和traceroute命令的功能并入了同一个工具中，实现更强大的功能。
Linux版本的mtr命令默认发送ICMP数据包进行链路探测。可以通过“-u”参数来指定使用UDP数据包用于探测。
相对于traceroute命令只会做一次链路跟踪测试，mtr命令会对链路上的相关节点做持续探测并给出相应的统计信息。所以，mtr命令能避免节点波动对测试结果的影响，所以其测试结果更正确，建议优先使用。
2.MTR使用方法
在Linux系统上使用
用法说明
mtr [-hvrctglspni46] [-help] [-version] [-report] [-report-cycles=COUNT] [-curses] [-gtk] [-raw] [-split] [-no-dns] [-address interface] [-psize=bytes/-s bytes] [-interval=SECONDS] HOSTNAME [PACKETSIZE]
常见可选参数说明：
-r 或 -report：以报告模式显示输出。 -p 或 -split：将每次追踪的结果分别列出来。 -s 或 -psize：指定ping数据包的大小。 -n 或 -no-dns：不对IP地址做域名反解析。 -a 或 -address：设置发送数据包的IP地址。用于主机有多个IP时。 -4：只使用IPv4协议。 -6：只使用IPv6协议。另外，也可以在mtr命令运行过程中，输入相应字母来快速切换模式。？或 h：显示帮助菜单。 d：切换显示模式。 n：切换启用或禁用DNS域名解析。 u：切换使用ICMP或UDP数据包进行探测。
3.示例输出
66551dfc-e715-4d2f-8f07-d2960523e4b8-image.png
默认配置下，返回结果中各数据列的说明如下。
第一列（Host）：节点IP地址和域名。如前面所示，按n键可以切换显示。
第二列（Loss%）：节点丢包率。
第三列（Snt）：每秒发送数据包数。默认值是10，可以通过参数“-c”指定。
第四列（Last）：最近一次的探测延迟值。
第五、六、七列（Avg、Best、Wrst）：分别是探测延迟的平均值、最小值和最大值。
第八列（StDev）：标准偏差。越大说明相应节点越不稳定。

1、利用xfel软件

利用xfel软件去初始化内存，并将bin文件直接烧录到内存中执行。这种方式需要注意程序的链接地址，链接脚本要做相应修改。

2、剥离内存初始化代码

（1）在xfel软件的源码里有这部分代码；源码地址：https://github.com/xboot/xfel；
（2）在SDK包里的spl代码里也有内存初始化代码；
我还没有将内存初始化代码部分剥离出来，最近也不打算继续研究，后续有剥离出内存初始化代码的同志，请@我分享一下，谢谢。

udp --- 用户数据报协议，是一个无连接的简单的面向数据报的运输层协议。
udp不提供可靠性，它只是把应用程序传给IP层的数据报发送出去，但是并不能保证它们能到达目的地。
udp在传输数据报前不用在客户和服务器之间建立一个连接，且没有超时重发等机制，故而传输速度很快。
udp是一种面向无连接的协议，每个数据报都是一个独立的信息，包括完整的源地址或目的地址，它在网络上以任何可能的路径传往目的地，因此能否到达目的地，到达目的地的时间以及内容的正确性都是不能被保证的。

udp通讯流程很简单，具体步骤如下：

微信图片_20230908105059.png

udp服务端代码
#include <stdio.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #include <sys/socket.h> #include <stdlib.h> #include <netinet/in.h> #include <arpa/inet.h> #include <stdbool.h> #include <pthread.h> #define BUFFER_SIZE 1024 // buf size struct CONNECT_INFO { struct sockaddr_in client_addr; }; static int sock_fd; static volatile bool is_connect = false; bool udp_server_init(short port) { struct sockaddr_in server_addr; sock_fd = socket(AF_INET, SOCK_DGRAM, 0); if (sock_fd == -1) { perror("socket"); return false; } // initialize address. bzero(&server_addr, sizeof(server_addr)); server_addr.sin_family = AF_INET; server_addr.sin_port = htons(port); server_addr.sin_addr.s_addr = htonl(INADDR_ANY); // bind the local port. if ((bind(sock_fd, (struct sockaddr *)&server_addr, sizeof(struct sockaddr_in))) == -1) { perror("bind"); return false; } return true; } void *send_thread(void *arg) { struct CONNECT_INFO *info = (struct CONNECT_INFO *)arg; if (info == NULL) { printf("error connect info"); return (void*)-1; } while (1) { char send_buf[BUFFER_SIZE]; bzero(send_buf, sizeof(send_buf)); // input from keyboard. char *str = fgets(send_buf, sizeof(send_buf), stdin); if (str == NULL) { perror("fgets"); continue; } if (strlen(str) <= 1) { continue; } if(is_connect == false) { printf("No client are available!\n"); continue; } // send data. if ((sendto(sock_fd, send_buf, strlen(str) - 1, 0, (struct sockaddr *)&info->client_addr, sizeof(struct sockaddr_in))) < 0) { perror("sendto"); continue; } } return (void*)0; } int main(int argc, char *argv[]) { // check your input. if (argc != 2) { printf("Usage:\n"); printf(" %s <port number>\n", argv[0]); return -1; } short port = atoi(argv[1]); bool ret = udp_server_init(port); if (ret == false) { goto err; } pthread_t t_id; struct CONNECT_INFO info; socklen_t addr_len = sizeof(struct sockaddr_in); memset(&info, 0, sizeof(info)); pthread_create(&t_id, NULL, send_thread, (void *)&info); pthread_detach(t_id); printf("Waiting for client connectionn\n"); while (1) { // recive from client. char recv_buf[BUFFER_SIZE]; bzero(recv_buf, sizeof(recv_buf)); if ((recvfrom(sock_fd, recv_buf, sizeof(recv_buf), 0, (struct sockaddr *)&info.client_addr, &addr_len)) <= 0) { perror("recvfrom"); goto err; } printf("[Recv from client %s:%d] : %s\n", inet_ntoa(info.client_addr.sin_addr), htons(info.client_addr.sin_port), recv_buf); is_connect = true; } close(sock_fd); return 0; err: close(sock_fd); return -1; }
udp客户端代码：

如何确认是什么中断唤醒的芯片
Wireless & Analog Series • Posted at • newcastle

@newcastle
该部分对应的代码是：src/pm/pm.c ： pm_check_wakeup_irqs
/* Check if there are any interrupts pending */ addr = (unsigned int *)NVIC->ISPR; for (i = 0; i < DIV_ROUND_UP(NVIC_PERIPH_IRQ_NUM, 32); i++) { val = addr[i]; irq[i] = val & nvic_int_mask[i]; if (irq[i]) { PM_LOGD("nvic[%d]:%x, mask:%x en:%x\n", i, val, nvic_int_mask[i], NVIC->ISER[i]); ret |= PM_WAKEUP_SRC_DEVICES; } }
NVIC->ISPR寄存器也就是中断挂起控制寄存器组，代表有中断产生，每一位对应一个中断，可以看到唤醒中断是nvic[1]，8也就是0b1000，也就是对应（nvic[0]）31 + 4 = 35号中断。

XR806对应的芯片中断序号在include/driver/chip/chip.h里面定义。
/*!< Interrupt Number Definition */ typedef enum { /* Cortex-M4/3 Processor Exceptions Numbers*/ NonMaskableInt_IRQn = -14, /*!< 2 Non Maskable Interrupt */ MemoryManagement_IRQn = -12, /*!< 4 Cortex-M3 Memory Management Interrupt */ BusFault_IRQn = -11, /*!< 5 Cortex-M3 Bus Fault Interrupt */ UsageFault_IRQn = -10, /*!< 6 Cortex-M3 Usage Fault Interrupt */ #if defined(CONFIG_CPU_CM33F) SecureFault_IRQn = -9, /*!< 7 Cortex-M33 Secure Fault Interrupt */ #endif SVCall_IRQn = -5, /*!< 11 Cortex-M3 SV Call Interrupt */ DebugMonitor_IRQn = -4, /*!< 12 Cortex-M3 Debug Monitor Interrupt */ PendSV_IRQn = -2, /*!< 14 Cortex-M3 Pend SV Interrupt */ SysTick_IRQn = -1, /*!< 15 Cortex-M3 System Tick Interrupt */ /* Specific Interrupt Numbers */ DMA_IRQn = 0, GPIOA_IRQn = 1, #if (CONFIG_CHIP_ARCH_VER == 2) SDC0_IRQn = 2, #endif UART0_IRQn = 4, UART1_IRQn = 5, SPI0_IRQn = 6, #if (CONFIG_CHIP_ARCH_VER == 2) SPI1_IRQn = 7, #endif I2C0_IRQn = 8, I2C1_IRQn = 9, WDG_IRQn = 10, TIMER0_IRQn = 11, TIMER1_IRQn = 12, RTC_SEC_ALARM_IRQn = 13, RTC_WDAY_ALARM_IRQn = 14, #if (CONFIG_CHIP_ARCH_VER == 2) CSI_JPEG_IRQn = 15, #endif I2S_IRQn = 16, PWM_ECT_IRQn = 17, CE_IRQn = 18, GPADC_IRQn = 19, GPIOB_IRQn = 20, IRRX_IRQn = 22, IRTX_IRQn = 23, A_WAKEUP_IRQn = 25, FLASHC_IRQn = 26, UART2_IRQn = 27, #if (CONFIG_CHIP_ARCH_VER == 2) SDC1_IRQn = 28, #endif WIFIC_IRQn = 29, CODEC_DAC_IRQn = 30, CODEC_ADC_IRQn = 31, AVS_IRQn = 32, /* AVS psensor */ #if (CONFIG_CHIP_ARCH_VER == 2) GPIOC_IRQn = 33, PSRAMC_IRQn = 34, #endif #if (CONFIG_CHIP_ARCH_VER == 3) BLE_LL_IRQn = 35, BTCOEX_IRQn = 36, KEYSCAN_IRQn = 37, SMCARD_IRQn = 38, DMA_SEC_IRQn = 39, CAPSEN_IRQn = 40, LPUART0_IRQn = 41, LPUART1_IRQn = 42, TZASC_IRQn = 43, #endif } IRQn_Type;
可以看到是因为蓝牙中断唤醒的，在休眠关闭蓝牙前关闭广播可以解决。

对于随机数要求不高的应用，可以选择从/dev/urandom设备获取随机数来避免该问题，因为它在熵源不足时会使用伪随机数算法来生成数据，不会出现阻塞现场。

缺点：获取的是伪随机数，随机性差

1、第一次烧录成功了，证明你的flash驱动应该是支持这颗nand的，所以可以烧进去
2、但烧录进去不代表你flash驱动中的ID配置一定是正确的，有可能你拿到的flash驱动中对这颗物料的参数配置（坏块标记位、oob区域划分、ecc校验能力等）配置不正确，导致你第一次烧录的时候，在这颗flash上误标记了bad block，故后续烧录或者启动会提示很多的“bad block......”
3、建议找一个常用型号的flash，先替换上去，看下是否能正常启动，可以试一下这款（MX35LF1GE4AB），这款在很早之前的驱动已经是支持的了

@zzz555 The clock signal may be operating at a speed outside the bandwidth of your oscilloscope. Check the Hz setting of your clock, and ensure it is less than the bandwidth of the oscilloscope (likely 100 MHz).

If it is higher, then the signal will be attenuated. Configure the scope to be AC-coupled and try increasing the scope gain to see a faint signal.

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。

downloadFileByUrl.jpg

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

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。

@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。

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！
[ 1.079831] spi_test 100000000 == get 100000000 ␍␊ [ 1.093426] spi_test 99000000 == get 96000000 ␍␊ [ 1.098527] spi_test 98000000 == get 96000000 ␍␊ [ 1.103587] spi_test 97000000 == get 96000000 ␍␊ [ 1.108714] spi_test 96000000 == get 96000000 ␍␊ [ 1.113807] spi_test 95000000 == get 92307692 ␍␊ [ 1.118905] spi_test 94000000 == get 92307692 ␍␊ [ 1.123996] spi_test 93000000 == get 92307692 ␍␊ [ 1.129127] spi_test 92000000 == get 87771428 ␍␊ [ 1.134193] spi_test 91000000 == get 87771428 ␍␊ [ 1.139293] spi_test 90000000 == get 87771428 ␍␊ [ 1.144406] spi_test 89000000 == get 87771428 ␍␊ [ 1.149506] spi_test 88000000 == get 87771428 ␍␊ [ 1.154601] spi_test 87000000 == get 85714285 ␍␊ [ 1.159739] spi_test 86000000 == get 85714285 ␍␊ [ 1.164835] spi_test 85000000 == get 80000000 ␍␊ [ 1.169939] spi_test 84000000 == get 80000000 ␍␊ [ 1.175074] spi_test 83000000 == get 80000000 ␍␊ [ 1.180142] spi_test 82000000 == get 80000000 ␍␊ [ 1.185243] spi_test 81000000 == get 80000000 ␍␊ [ 1.190346] spi_test 80000000 == get 80000000 ␍␊
就可以知道，有一些值设置是不行的！要特定值才行！
