从 APSS 更新 RTSS 软件镜像

本主题介绍通过邮箱（Mailbox）接口从 APSS 更新 RTSS 软件镜像的可用方法。

​

使用 Fastboot 方法更新软件镜像

使用 Fastboot 方法将 RTSS 软件镜像烧写到设备上。

​

前提条件

1. 设备必须处于已启动状态。
2. 设置调试 UART.

​

步骤

1. 在 APSS UART 控制台中运行以下命令，使设备进入 Fastboot 模式：

   reboot bootloader
   

2. 运行以下 fastboot 命令，将 sailhyp.elf 和 sailsw1.elf 镜像烧写到 RTSS 分区：

   fastboot flash <partition_name> <software image path>
   

   例如：

   linuxhost@machine:~$ fastboot flash sail_hyp_a  <path name>/qcs9075-iq-9075-evk/qcom-multimedia-image/sail_nor/sailhyp.elf
   Sending 'sail_hyp_a' (632 KB)                      OKAY [  0.123s]
   Writing 'sail_hyp_a'                               OKAY [  8.500s]
   Finished. Total time: 8.756s
   

   linuxhost@machine:~$ fastboot flash sail_sw1_a  <path name>/qcs9075-iq-9075-evk/qcom-multimedia-image/sail_nor/sailsw1.elf
   Sending 'sail_sw1_a' (1710 KB)                     OKAY [  0.123s]
   Writing 'sail_sw1_a'                               OKAY [ 20.185s]
   Finished. Total time: 20.448s
   

   注意sailhyp.elf 和 sailsw1.elf 镜像位于 <Path name>\qualcomm-linux-spf-1-0_ap_standard_oem_sail\SAIL.SI.1.2\sail_proc\build\ms\bin\SAIL_RTOS\DEBUG\lemans\signed\。

RTSS 软件镜像成功更新后，将显示以下日志：

• APSS 日志：

使用 sail_updater 工具更新软件镜像

​

前提条件

1. 设备必须处于已启动状态。
2. 设置调试 UART.

​

步骤

1. 在 APSS UART 控制台中运行以下命令，创建用于复制 sailhyp.elf 和 sailsw1.elf 镜像的测试文件夹：

   mount -o rw,remount /
   

   cd tmp/
   
   mkdir test
   
2. 将 sailhyp.elf 和 sailsw1.elf 镜像文件推送到 /tmp/test 目录。 例如：

   adb push sailhyp.elf /tmp/test
   268 KB/s (645792 bytes in 2.346s)
   

   adb push sailsw1.elf /tmp/test
   295 KB/s (950144 bytes in 3.138s)
   

3. 启用对 sailhyp.elf 和 sailsw1.elf 镜像的访问权限。

   chmod 777 /tmp/test/*.elf
   

4. 烧写 sailhyp.elf 和 sailsw1.elf 镜像。

   sail_updater -r 0 -p /tmp/test
