昨天下班前放著的 device 又卡住了

先 build 一版不會自動重開機的來試一下怎麼從 linux 來控制 GPIO

發現一 turn off the IO control power 就再也起不來了 - 照理說 uboot 會把電拉起來才對呀

再改一下 icosmain.c - 拉成 low 後睡個 2 秒再拉成 high

再度測試

又卡住了

### module <schedule-reboot> init
### module <wifi_apsta> init
### module <wifi_ate> init
 icos: reboot...
reset the IO control power
.

### module <wifi_ate> exit

### module <openvpn> exit
### module <vcom> exit

看來斷電的時間點要往後調一下

不過過了快兩分鐘竟然又動了

看來是斷電再開讓 module <lte> exit 卡了快兩分鐘

找一下怎麼在 shell 去控制 GPIO

以 GPIO5-IO9 而言

//GPIO export, called before any other IO
int GPIOExport(int port, int pin)
{
    int number = _get_gpio_number(port, pin);

    char path[GPIO_PATH_LEN];
    if (access(_get_gpio_path(number, path, sizeof(path)), F_OK) == 0)
    {
        return RETCODE_SUCCESS;
    }

    return _write_gpio_value(GPIO_EXPORT, "%d", number);
}

gpio_number 為 (5 - 1) * 32 + 9 = 137

我要先 export

bash-4.3# echo 137 > /sys/class/gpio/export

然後要設定方向

bash-4.3# echo out > /sys/class/gpio/gpio137/direction
bash-4.3# cat /sys/class/gpio/gpio137/direction
out

然後就去寫值了

bash-4.3# echo 0 > /sys/class/gpio/gpio137/value

1430

開機試試吧

整理一次這禮拜的工作摘要

  • M300
    • Set to SIM 1 slot in uboot
      • done
    • WiFi: hidden page (ATE)
      • done
    • WiFi: warm reboot cause hang
      • 從 uboot 去控制該 io control power GPIO 的話 - 約 30 次裡有一次沒有拉成 low
      • 試著讓 uboot 負責第一時間把 io control power GPIO 拉成 high; linux 負責在 restart 前拉成 low
    • Cisco DMVPN
    • Wizard
    • MFG tool with UBI
  • M360
    • Schedule Reboot

就這樣寫週報吧

還沒有 hang 住

看來可以把板子拿給 morris 讓他把 io control power 的控制從 GPIO5-IO9 改回 GPIO4-IO21

來改一下 code

rc.local - sleep 個 9 秒便觸發 reboot

搭配 morris 改完的板子

開機做測試

1645

morris 表示從 web ui 去 restart 大概 20 多次會有一次 reset ic 會沒有 reset

就是因為這樣他才不敢直接用那顆 reset ic 來跟 ic control power 連動

才特別拉一根 GPIO 到 io control power 讓我來控制

john 提到說會不會是因為 /usr/sbin/icosconfig coldreboot 的關係導致 morris 發現的現象

這等下禮拜可以來試一下

rc.local 裡 /usr/sbin/icosconfig coldreboot 換成 reboot 即可

從目前的 SysReboot.sh 來看 SysReboot.sh

turn off the IO control power 這件事會失敗肯定不是後面的 linux reboot 害的

那只有可能是前面的 icosconfig coldreboot

再來改一版

不做 /usr/sbin/icosconfig shutdown 1>/dev/console 2>&1
