      实在抱歉,由于这批液晶的FPC老化比较严重,年后大约只能提供20片左右焊好的板子(带液晶,不带RTL8723DS,不带FLASH,不带电池)给各位朋友了。

      排线焊接之后,可能由于高温,导致本来就很脆的FPC断路更严重了。

      @memory 在menuconfig下也可以使用“/”搜索想要的配置项关键字。有些功能模块是选中了,它所依赖的功能模块也一并会被选中,或者看help也可以把依赖项都手工选中,但是有些驱动或者功能模块是想要正常工作需要多个配置单独设置的,如串口的内核启动打印,需要打开printk,需要设置log_level,需要配置字符设备,根据soc不一样还需要选中特定的串口驱动,类似于这种组合式配置只能通过经验或者问原厂来解决吗?

      【XR806开发板试用】使用FDCM操作Flash记录开机次数

      @funfulzhao 在 【XR806开发板试用】使用FDCM操作Flash记录开机次数 中说:

      一、寻找系统分配的自定义用户数据地址
      (1)XR806的Flash布局
      d9b423b2-e419-447a-a36e-818449e30c25-image.png
      如图1所示,FLASH的布局有两种:
      1、没有开启OTA模式;Image1+Padding+Sysinfo
      2、开启OTA模式;Image1+Padding+Sysinfo+OTA area +Image2 +Padding
      fa07eb9a-2cee-4fb6-ad75-f861b6248859-image.png 9fad5ccc-1b5a-4488-a518-24ccb92dee9f-image.png

      如图2/3,当前工程采用wlan_ble_demo,未开启OTA模式,
      查看device/xradio/xr806/xr_skylark/project/demo/wlan_ble_demo/gcc/Makefile文件,Flash的cfg文件为IMAGE_CFG := ./image_wlan_ble.cfg
      5b720328-f4b2-4752-9cc2-003f46d192ec-image.png
      (2)查看Sysinfo的地址
      Sysinfo区域是一段用于存储用户自定义数据的区域,紧跟在Image1区域后面,通过device/xradio/xr806/xr_skylark/project/demo/wlan_ble_demo/prj_config.h得知Sysinfo的地址和长度
      368e49bc-fca2-4c5a-b46e-901cfe7cf93d-image.png
      二、使用FDCM操作Sysinfo区域
      FDCM模块与SDK中其他模块之间的关系如下图所示。Sysinfo,OTA和IMAGE等模块中都有使用到FDCM模块接口,保存其对应的数据。
      bf44d439-26a6-4dd9-aba5-63f0763e2202-image.png
      注意:(1)FDCM操作的区域需要与Flash可擦除的Block对齐;
      (2)FDCM模块管理的Flash区域不要与其他模块(如Image)使用的Flash区域产生冲突,避免相互影响
      (3)用FDCM模块管理的Flash区域必须与Flash可擦除的block对齐,即区域起始地址与Flash擦除Block的边缘对齐,并且区域大小为Flash可擦除最小Block大小的整数倍
      三、实现代码

      #include <stdio.h> #include <unistd.h> #include <string.h> #include <stdlib.h> #include "ohos_init.h" #include "kernel/os/os.h" #include "sys/fdcm.h" #include "common/framework/platform_init.h" #define FLASH_DEVICE_NUM 0 #define IoT_FLASH 1 #define FDCM_FLASH_START_ADDR (1536*1024) #define FDCM_SIZE (4*1024) static OS_Thread_t g_main_thread; static void MainThread(void *arg) { fdcm_handle_t *fdcm; uint8_t write_buf[100]; uint8_t read_buf[100]; fdcm = fdcm_open(FLASH_DEVICE_NUM, FDCM_FLASH_START_ADDR, FDCM_SIZE); if (fdcm == NULL) { printf("fdcm open fail.\n"); return ; } printf("fdcm open success, flash addr:0x%x, flash size:%d\n", FDCM_FLASH_START_ADDR, FDCM_SIZE); printf("we can use fdcm to save info to flash.\n"); fdcm_read(fdcm, &read_buf, sizeof(read_buf)); if(strlen(read_buf)==0) { printf("first power on \r\n"); sprintf((char *)write_buf,"%d",1); fdcm_write(fdcm, &write_buf, sizeof(write_buf)); } else { printf("read_buf = %d\r\n",atoi((char *)read_buf)); sprintf(write_buf,"%d",atoi((char *)read_buf)+1); printf("write_buf = %d\r\n",atoi((char *)write_buf)); fdcm_write(fdcm, &write_buf, sizeof(write_buf)); } LOS_Msleep(10); fdcm_read(fdcm, &read_buf, sizeof(read_buf)); LOS_Msleep(20); printf("Power-on times:%s\r\n",read_buf); fdcm_close(fdcm); } void FlashTestMain(void) { printf("FDCM Flash Test \r\n"); if (OS_ThreadCreate(&g_main_thread, "MainThread", MainThread, NULL, OS_THREAD_PRIO_APP, 4 * 1024) != OS_OK) { printf("[ERR] Create MainThread Failed\n"); } } SYS_RUN(FlashTestMain);

      五:遗留问题
      (1)Image的max_size为1532K,设置FDCM的起始地址为(15321024)时,本次开机的写入读取未报错,但是数据未保存;FDCM的起始地址改为(15361024),则正常。
      六:参考

      @i_a_student 果真如此。多谢指点!👍 原来把默认的路径注释掉了。刚开始创建tools文件夹的位置和官方的路径不一样,路径做了些修改,编译的时候中间出现过很多问题,又把tools文件夹copy到官方指定的路径。config删掉新路径的同时忘记删掉默认的路径前面#。犯了个低级错误。

      哈哈,抱歉来晚了。
      整理一下Wi-Fi的启动流程:
      1.系统启动通过sunxi-rf驱动读取board.dts配置,解析供电,sdio,引脚,时钟等配置。完成上电动作。
      2.驱动加载时完成扫卡,下载firmware,add wlan0 interface。
      3.系统的自启动脚本在etc/init.d/wpa_supplicant中启动服务,启wlan0。
      4.利用wpa_cli/wifimanager进行应用的操作。
      上面的错误
      建议排查思路:
      1.系统起来执行lsmod 查看xradio_mac/xradio_core/xradio_wlan(也有可能是单ko的形式xr829)驱动是否加载成功。
      顺便提一下驱动加载失败最常见的错误:

      1.供电不匹配。 2.扫卡时失败,sdio配置错误。 3.下载firmware失败。(注意路径:默认是/lib/firmware)

      2.执行ps | grep wpa_supplicant查看服务是否启动。
      也可以直接执行

      ./etc/init.d/wpa_supplicant start //再次手动启动

      服务启动失败的常见原因:

      1.前面驱动加载已经失败了,导致没有wlan0 interface. 2.配置文件不存在比如:wpa_supplicant.conf。默认是在/etc/wifi、目录下 3.文件存在,但是文件系统只读,导致无法对配置文件写操作。

      可以手动执行wpa_supplicant命令起服务就可以看到提示如下:

      Successfully initialized wpa_supplicant [ 796.252780] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready mkdir[ctrl_interface=/etc/wifi/sockets]: **Read-only file system** Failed to initialize control interface '/etc/wifi/sockets'. You may have another wpa_supplicant process already running or the file was left by an unclean termination of wpa_supplicant in which case you will need to manually remove this file before starting wpa_supplicant again. nl80211: deinit ifname=wlan0 disabled_11b_rates=0

      解决办法:
      1.直接修改文件系统,换成可读写的,例如ext4.
      2.可以自己临时创建配置文件到/tmp目录。

      使用afalg小块性能非常拉胯,可能是受限于内核通信或硬件中断之类的吧。
