零知识玩转AVH（5）—— 怎么玩（4）

接前一篇文章：零知识玩转AVH（4）—— 怎么玩（3）

上一回经过了一个艰苦的探索过程，最终完成了“arm-avh-best-practice-project-product-subscription-guide-cn.pdf”即“Arm虚拟硬件实践专题一：产品订阅指南（百度智能云版）”中的第2步：连接Arm虚拟硬件（AVH）云服务器BCC实例。本回结合实际操作，详细讲解第3步：查看Arm虚拟硬件（AVH）云服务器BCC实例预装软件清单。

上一回最终通过SecureCRT中的SSH方式成功连接了远程云服务器。成功登录后，界面如下：

3. 查看Arm虚拟硬件（AVH）云服务器BCC实例预装软件清单

Arm虚拟硬件（AVH）云服务器BCC实例预装的Arm相关软件工具清单，可以通过以下两种方式查看：

（1）云市场Arm虚拟硬件产品详情页的规格参数介绍中的“集成服务组件及版本”。

产品参数

交付形式：镜像交付
交付时间：实时
系统类型：Linux
基础系统版本：Ubuntu,20.04 LTS aarch64 (64bit)
集成服务组件及版本：Arm 工具及其版本信息如下： Arm Compiler 6.18 GCC compiler 11.2 CMSIS-Toolbox 1.2.0 FVP模型: VHT_MPS2_Cortex-M0: 11.19.25 VHT_MPS2_Cortex-M0plus: 11.19.25 VHT_MPS2_Cortex-M3: 11.19.25 VHT_MPS2_Cortex-M4: 11.19.25 VHT_MPS2_Cortex-M7: 11.19.25 VHT_MPS2_Cortex-M23: 11.19.25 VHT_MPS2_Cortex-M33: 11.19.25 VHT_MPS3_Corstone_SSE-300: 11.19.25 VHT_Corstone_SSE-300_Ethos-U55: 11.19.25 VHT_Corstone_SSE-300_Ethos-U65: 11.19.25 VHT_Corstone_SSE-310: 11.19.25 VHT_Corstone_SSE-310_Ethos-U65: 11.19.25

（2）登录AVH BCC实例（登录后默认目录为：/home/ubuntu），运行以下命令将自动显示当前AVH BCC实例中安装的Arm软件工具清单及版本信息。同时，在该目录下会自动生成文本文件tool-inventory.txt，该文件记录了所显示的工具清单及版本信息。

由于是以root用户登录的，因此登录后默认路径为：

root@instance-eoy24hji:/home/ubuntu# ls
ArmVirtualHardwareTargets_EULA.pdf  packs  tool-inventory.sh
root@instance-eoy24hji:/home/ubuntu#

tool-inventory.sh文件的内容如下：

#!/bin/bash

# Print an inventory of the installed tools.

# record the output of this script into a text file
exec > >(tee -i tool-inventory.txt)

COLOR=`tput setaf 4`
BCOLOR=`tput setab 7`
RESET=`tput sgr0`

arch=$(uname -m)

# Arm Compiler

armclang --target=arm-arm-none-eabi --version
echo -e "\n"

# GNU Compiler
echo "${COLOR}${BCOLOR}GNU Compiler information: ${RESET}"

for i in $(ls /opt/VHT/VHT_*); do
        echo "  ${COLOR}${BCOLOR}$(basename $i) information: ${RESET}"
        $i --version
        echo -e "\n"
done

# Vela Compiler
# echo "${COLOR}${BCOLOR}Vela Compiler information: ${RESET}"
# vela --version
# echo -e "\n"

执行以下命令：

./tool-inventory.sh

命令及结果如下：

与文档“arm-avh-best-practice-project-product-subscription-guide-cn.pdf”即“Arm虚拟硬件实践专题一：产品订阅指南（百度智能云版）”中所给出的结果基本一致。

此外，若仅想查看Arm虚拟硬件（AVH）镜像支持的Arm固定虚拟平台（Fixed Virtual Platform，FVP），可以运行以下命令：

ls /opt/VHT/VHT*

实际命令及结果如下：

root@instance-eoy24hji:/home/ubuntu# ls /opt/VHT/VHT*
/opt/VHT/VHT_Corstone_SSE-300_Ethos-U55  /opt/VHT/VHT_Corstone_SSE-310_Ethos-U65  /opt/VHT/VHT_MPS2_Cortex-M23  /opt/VHT/VHT_MPS2_Cortex-M4
/opt/VHT/VHT_Corstone_SSE-300_Ethos-U65  /opt/VHT/VHT_MPS2_Cortex-M0              /opt/VHT/VHT_MPS2_Cortex-M3   /opt/VHT/VHT_MPS2_Cortex-M7
/opt/VHT/VHT_Corstone_SSE-310            /opt/VHT/VHT_MPS2_Cortex-M0plus          /opt/VHT/VHT_MPS2_Cortex-M33  /opt/VHT/VHT_MPS3_Corstone_SSE-300

以上结果就是目前支持的FVP模型清单。

至此，第三步“3. 查看Arm虚拟硬件（AVH）云服务器BCC实例预装软件清单”就完成了。第一篇文档“arm-avh-best-practice-project-product-subscription-guide-cn.pdf”即“Arm虚拟硬件实践专题一：产品订阅指南（百度智能云版）”中的全部内容也就都结合实操讲解完了。

按照计划原，下一回应该开始讲解第二篇文档：arm-avh-best-practice-project-fvp-model-getting-started-guide-cn.pdf，即Arm虚拟硬件实践专题二：Arm虚拟硬件FVP模型入门指南。但是，笔者决定还是优先完成门槛任务，在此过程中可以边做边研究第二个文档的内容，在实践中学习效率才更高。因此，下一回就开始实际完成门槛任务了，会对于完成门槛任务的全步骤、以及遇到问题和解决问题的过程进行详细解析。

欲知后事如何，且看下回分解。
