10.2.3. 参数配置

首先需要搭建好基本的网络环境(使用网口或在C3模块)

10.2.3.1. RTOS配置

使能 OTA 相关配置，自动使能了 ENV 相关配置

在 工程 根目录下执行 scons –menuconfig，进入menuconfig的功能配置界面，按如下选择：

Local packages options  --->
    Third-party packages options  --->
        [*] ota_downloader: The firmware downloader which using on RT-Thread OTA component  --->
            [ ]   Enable HTTP/HTTPS OTA
            [ ]   Enable Ymodem OTA
            [*]   Enable Uart OTA
            Version (latest)  --->

    ZX packages options  --->
        [*] aic-env  --->
            -*-   Enable ENV interface and CMD
            [*]     Enable redundant environment support
            (env)   Env part name
            (env_r) Env redundant part name
            (4096)  Environment Size
            [ ]     Enable ENV debug
            -*-   Enable A/B system support
        [*] aic-ota  --->
            [ ]   Enable OTA downloader debug
            [*]   Enable OTA interface

备注

为了方便配置, 使能 AIC_OTA_INTERFACE 后, 会自动选上 AIC_ENV_INTERFACE , AIC_AB_SYSTEM_INTERFACE

10.2.3.2. Boot 配置

使能 ENV 相关配置

在 工程 根目录下执行 scons –menuconfig，进入menuconfig的功能配置界面，按如下选择：

Local packages options  --->
    ZX packages options  --->
        [*]   Enable ENV interface and CMD
        [*]     Enable redundant environment support
        (env)   Env part name
        (env_r) Env redundant part name
        (4096)  Environment Size
        [ ]     Enable ENV debug
        [*]   Enable A/B system support in bootloader

10.2.3.3. application 配置

开启 AIC_AB_SYSTEM_INTERFACE 后，在对应app demo下，需在main.c中手动添加挂载代码

int main(void)
{
#ifdef AIC_AB_SYSTEM_INTERFACE
    char target[32] = { 0 };
    enum boot_device boot_dev = aic_get_boot_device();

    if (boot_dev != BD_SDMC0) {

        aic_ota_status_update();
        aic_get_rodata_to_mount(target);
        printf("Mount APP in blk %s\n", target);

        if (dfs_mount(target, "/rodata", "elm", 0, 0) < 0)
            printf("Failed to mount elm\n");

        memset(target, 0, sizeof(target));

        aic_get_data_to_mount(target);
        printf("Mount APP in blk %s\n", target);

        if (dfs_mount(target, "/data", "elm", 0, 0) < 0)
            printf("Failed to mount elm\n");
    }
#endif
    return 0;
}

10.2.3.4. 配置说明

ZX OTA 采用A/B 系统方案，需要配置双系统分区，即在对应工程配置的 image_cfg.json 文件中配置分区表(以M4为例)

        "size": "128m", // Size of SPI NAND
