FOTA 固件升级

配置 FOTA 支持

boot yaml 配置

FOTA yaml 相关配置文件路径：

  • solutions/cv181x_boot/package.yaml

YAML 文件中需要开启的配置如下所示：

  - sec_crypto: develop
  - key_mgr: develop
  - bootab: develop
  - xz: develop

  CONFIG_NO_OTA_UPGRADE: 0

  CONFIG_SEC_CRYPTO_AES_SW: 1
  CONFIG_SEC_CRYPTO_SHA_SW: 1
  CONFIG_SEC_CRYPTO_RSA_SW: 1
  CONFIG_SEC_CRYPTO_RNG_SW: 1

flash yaml 配置

配置文件路径：

  • boards/cv181xc_qfn/configs/config.yaml

对于有 FOTA 需求的分区，需增加update和car配置

以下为供参考的分区配置，在该配置中挂载了新的分区 lfs并进行 FOTA

partitions:
  - {
      name: lfs,
      address: 0x4DE000,
      size: 0x850000,
      index: 0,
      filename: lfs.bin,
      update: FULL,
      car: xz,
    }

Note

其中，misc分区用作升级备份分区，升级固件通过网络下载后默认存放至该分区中

升级固件放置

需要把固件上传到平头哥芯片开发社区生成升级包，并选择合适的升级策略

具体操作流程请参考升级方案

boot更新

  • 配置完成后使用 make cv181x_boot 命令，编译生成支持 FOTA 的 boot.bin文件
    • 文件路径为solutions/cv181x_boot
  • 将其重命名为 boot ，替换原固件中的 boot 文件并进行烧录

    正常编译流程默认会将boards/cv18*/bootimgs/boot文件拷贝至升级固件images文件夹下，可使用新boot进行替换

FOTA 升级

FOTA 运行参考日志如下：

在升级完成后，misc分区数据被擦除，在后续板端重新启动过程中，由于检测到该分区数据被清空，从而不会重复升级
