M.I.B._More-Incredible-Bash: Harman MIB 2.x 软件开发工具箱

M.I.B. - More Incredible Bash - The Army knife for Harman MIB 2.x aka MHI2(Q) units 项目是一个为 Harman MIB 2.x 设备设计的综合开发工具库。它为开发人员提供了丰富的命令行工具以及脚本支持,帮助他们更好地管理、定制和调试基于 MIB 2.x 的车载信息娱乐系统。

项目背景与痛点

在开发针对 Harman MIB 2.x 设备的应用程序过程中,开发者面临着一系列技术与工具方面的挑战。传统工具可能难以直接满足开发流程中的具体需求,缺乏对 MIB 2.x 系统特性的直接支持。M.I.B. 项目正是为此而生,它为开发者提供了一套完备的工具链,从根本上解决了开发、调试和测试过程中的一系列痛点。有了这样一个强大的命令行工具集合,开发者可以更高效地进行开发、提升集成效率以及更好地调试系统。

核心技术揭秘

技术架构与设计模式

M.I.B._More-Incredible-Bash 项目的核心在于提供了大量的 Bash 脚本和命令行工具,使得开发者可以快速上手,直接进行 MIB 2.x 系统的开发与测试。这些工具在设计时充分考虑了用户的需求及复杂性,通过一系列灵活的模块化脚本进行实现,易于扩展并能够达到不错的执行效率。

通过这张图示可以看出,用户发起的任何命令都将经过脚本解析,然后进行命令分类处理,并最终调用相关脚本进行执行,最后返回结果给用户。这样模块化的处理方式使得项目具有很高的灵活性和扩展性。

核心算法与实现原理

核心的实现原理主要体现在命令行工具的系统化和模块化设计上。项目提供了大量的 Bash 脚本,每一次命令通过解析和分类处理,分别调用对应的脚本来完成任务,各个模块之间通过 Unix 管道机制进行协同工作,确保流畅且高效的执行流程。

功能亮点与差异

与市场上其他竞品相比,M.I.B._More-Incredible-Bash 的独特性主要体现在其对 MIB 2.x 系统的高度兼容、易用性和丰富的定制化能力。它支持的操作和配置极为细致,从底层系统设置到上层应用调试,每个环节都有所覆盖,并且代码完全开源,给予了开发者极大的自主权与定制空间。

应用场景与落地建议

开发者在实际应用中需注意以下几点:

  1. 环境准备:仔细阅读项目文档,尤其关注与特定硬件或操作系统相关的环境配置要求。
  2. 脚本定制:可根据具体需求定制脚本,充分发挥命令工具库的灵活性。
  3. 性能调试:利用提供的调试工具进行系统性能优化,确保平稳运行。

该项目适合于进行与 Harman MIB 2.x 设备密切相关的开发调试工作,包括但不限于车载信息娱乐系统上的应用程序开发、系统级配置与调试等。

综合评价

优点:

  • 丰富且易用的命令行工具集
  • 高度兼容 MIB 2.x 设备及其配置
  • 开源,利于定制及扩展

缺点:

  • 需深入学习才能完全掌握每一项工具的用法
  • 对于特定配置可能需要进一步探索和定制

综上,M.I.B._More-Incredible-Bash 是一款强大且灵活的工具箱,它极大地简化了与 Harman MIB 2.x 设备相关的开发流程,值得深入研究和使用。

M.I.B. - More Incredible Bash

GEM

All bastards who stolen and selling this should be fucked🖕

NOT FOR COMMERCIAL USE - IF YOU BOUGHT THIS YOU GOT RIPPED OFF!

M.I.B. is distributed under the GNU General Public License v2.0. See LICENSE for more information.

Check https://github.com/Mr-MIBonk/M.I.B._More-Incredible-Bash/wiki for even more details about M.I.B and your MHIG/MHI2/MHI2Q unit.

NOTE:

CAUTION:

  • Ensure that a external power is connected to the car during any flash or programming process!
  • It is not recommended to flash with running engine!
  • Power failure during flashing/programming will brick your unit.
  • All you do and use at your own risk!

M.I.B Functions:

Prepare SD card:

  • Extract all files of the M.I.B. to the root folder of a clean FAT32 formatted SD card
  • Make sure that your SD card is not write protected.
  • Patched IFS-stage2 images have to be placed on the SD card in the folder /patches
  • Pre-patched (CP, FEC and EL) ifs-root-stage2 images can be found for all recent MHI2 FW versions here: https://mib.mibsolution.one
  • You only have to copy the folder(s) you need for your car(s) - e.g. /patches/MHI2_ER_SKGxx_Pxxxx_MUxxxx_PATCH
  • They are already prepared in the right way, so that the tool can use them right away

There is also a example video guide available now:
image

FEC Generator:

  • M.I.B is generating custom FecContainer.fec files based on existing FecContainer.fec and addfec.txt in patch folder.
  • addfec.txt can be edited with any ASCII editor (Notepad++). DO NOT change EOL. Only not yet existing FECs will be added to container during the process.
  • Do NOT change FECContainer.fec with WhatTheFec tool, it will break file signature. M.I.B method will keep original FECs intact.

ExceptionList BUG

  • If your unit was patched with M.I.B before April 2021 run “Add new Fecs to FecContainer.fec” script in M.I.B -> PATCH.
  • This will switch over to FecContainer.fec based patch and avoid EL BUG - unit will get stuck during boot.

M.I.B. in Green Engineering Menu - GEM:

  • After M.I.B SD card is prepared
  • Insert the SD card into slot SD1 of your unit.
  • Enter Engineering/Red Menu to start SW Update. Select UPDATE, select SD card, select “FREE for all - M.I.B. Launcher V1.2”, START update.
  • Installation of M.I.B. on your Unit will start. The unit will restart three time until update process is finished.
  • GEM will be activated as part of the installation.
  • SVM error has to be cleared via M.I.B. function in GEM after installation
  • Enter GEM on your unit
  • Select ==>>m.i.b<<== in GEM and have FUN!

IMPORTANT! SD card must be presented in SD slot 1 (SD1) to enable M.I.B. in GEM. --> no SD no M.I.B.

  • GEM screen layout is designed for 9.2’’ screens but should work OK on 8’’ just some text lines may look cut

Update to new M.I.B. version:

  • No need to reinstall M.I.B if you want to use a new version.
  • Just create a fresh SD with latest M.I.B. version and insert into unit.

  • This method is still available in M.I.B, but no longer fully supported.
  • Basic functions are still available - Full functionality is only given via GEM
  • D-Link - e.g. DUB-E100 HW rev. D1 - USB-Ethernet adapter is required to connect to your MHI2 unit.
  • Use Putty/Kitty to connect via UART or Telnet (MIB IP:172.16.250.248) and login into RCC (recommended: port:123) or MMX (port:23).
  • Login and password for your units SW train has to be known.
  • Check your SW-train, a pre-patched ifs-root-stage2 has to be present within the folder /patches
  • Insert the SD card into slot SD1 of your MHI2 unit and login to the RCC shell:
Mount SD card in slot SD1
  • mount -uw /net/mmx/fs/sda0/
Start M.I.B by typing
  • /net/mmx/fs/sda0/start

  • Default screen size of Putty/Kitty is often too small to display the M.I.B. menu in full.

  • Increase the window size manually.
