我无法使用system_upgrade_start函数编译自己的固件版本。 SDK示例中的IoT_Demo正在编译成功。在我的情况下，编译器仅在我使用system_upgrade_start时才删除错误，当我仅删除此函数（而不是system_upgrade_userbin_check()）时，它编译时没有错误。制作固件需要做什么？
我的用户主要是例如：

需要将-lupgrade参数添加到编译器命令中。
如果编译器命令自动生成，则变量SDK_LIBS必须具有upgrade字面值，例如：
SDK_LIBS = c gcc phy pp net80211 wpa main lwip crypto ssl json driver upgrade
