One 、 Support automatic creation of production configuration

When developing equipment , If developers want to develop products based on a certain development board , It is often necessary to manually delete redundant files based on the downloaded source code 、 Manually modify the directory name and config.json To initialize the product engineering , Resulting in low development efficiency .

In order to solve the above problems , The new version DevEco Device Tool

Support the automatic creation of the minimum file set and directory structure required for production development according to the input inherited development board name and product name

, No extra files , There is no need to manually delete , Product development can be carried out directly .

Specific usage ：

chart 1  Support product configuration

• Pictured 1 Shown , Click create project  >  choice OpenHarmony Stable version  >  Choose what you want to download OpenHarmony Source version  >  Fill in engineering information  >  Click OK to start downloading OpenHarmony Mirror image .

• Then right-click in Explorer  >  choice OpenHarmony > Add new product >  Then fill in the supplier name in the product creation wizard , The product name , Inherited from the development board name and product name  >  After clicking OK, the directory structure and minimum file set of the product will be created with one click .

• Finally, according to the development guidance provided by the reference link , You can start incremental development .

Two 、 Support chip baseline engineering flow

Chip baseline engineering is the basis for module or device development . In the past, upstream chip manufacturers were adapting HarmonyOS Connect A baseline project will be generated , Downstream module or equipment manufacturers need to manually synchronize the chip baseline project before further development , Resulting in reduced efficiency .

In order to solve the above problems , The new version DevEco Device Tool New circulation capacity supporting chip baseline Engineering . Upstream chip manufacturers are completing HarmonyOS Connect After adaptation , Send code information 、 Code repository path 、 Tool chain of Resource Center URL Wait for the information to be packaged into profile File and upload DP（Device Partner） Platform hosting .

Downstream module / The equipment manufacturer obtains profile File can be used after DevEco Device Tool

One click Import and automatic parsing , It includes reading the chip definition information and automatically creating the directory structure and minimum file set corresponding to the chip 、 Read dependent compilation / Burn tool chain information and automatically download it from the Resource Center 、 To configure repo and git Tools and use repo download manifest Warehouse in the list , Greatly simplifies the development steps

, help HarmonyOS Connect Improve the efficiency of module or device development .

Besides , After the module or device development is completed ,DevEco Device Tool Also supports the manifest and profile Repackage the file , To upload to DP（Device Partner） The platform carries out subsequent hosting and circulation .

Specific usage ：

chart 2  One click Import of baseline project

• Pictured 2 Shown , Click create project  > choice HarmonyOS Connect Solution  > Choose download good profile File import .

• Then click OK ,DevEco Device Tool It will start automatically OpenHarmony Image download , Please wait patiently for the baseline project to download .

• After downloading, refer to the development guidance provided by the link , We can continue to develop products based on the baseline project provided by the chip manufacturer .

notes ：

In the import profile When you file , Such as  DevEco Device Tool It will automatically detect whether the dependent tools meet , If not, please click Repo linstallation Guide Refer to the instructions , Main reference links “ Prerequisite ” Of 5 Just one step .

3、 ... and 、 Support one click generation of standard equipment HDF General drive template

HDF（Hardware Driver Foundation） Drive frame , Provide driving framework capability for driving developers , Including driver loading 、 Drive service management and drive message mechanism . In the past HDF When developing , Developers need to write in different directories makefile file ,hcs file ,c++ Header and source files ,kconfig file , The operation steps are tedious .

In order to solve the above problems , The new version DevEco Device Tool newly added

Support one click generation standard （Standard） System HDF General drive template

To the corresponding code directory , To reduce the new HDF Operation steps of driving template , It improves the development efficiency for driving developers .

As shown in the following table , At present, only 2 Only products corresponding to source code types can be generated HDF, adopt HPM The imported distribution source code does not support generation HDF. When using this function , Please use DevEco Device Tool Provided OpenHarmony Stable version download OpenHarmony-v3.1-Release Source code , Or in the OpenHarmony Community download OpenHarmony master Version of the source code use .

Specific usage ：

chart 3  Generate HDF Driver template

After downloading the source code , Choose the product type , Then click on the graph 3 In the toolbar shown HDF >  stay HDF Select the blue drive module + You can create the required HDF Driver template .

Four 、 Integrate QEMU Emulator

In the process of embedded device development , It is often encountered that the code has been developed , Developers lack physical development boards , Unable to verify whether the image file generated by compilation works properly , Code debugging and error correction are also unavailable , Lead to the extension of equipment development cycle , Affect the project schedule .

In order to solve the above problems , The new version DevEco Device Tool  be based on QEMU

It provides the simulation capability of the development board , Support arm_virt and mps2-an386 Two simulation development boards , It can make the compiled image file of the source code run directly on the simulator

（ Currently only supported OpenHarmony V3.1 Release Source code ）, And provide Native Graphic display of application 、 visualization UI Interface and function interaction ability ; Besides ,

It also supports application on the development board / Kernel debugging , So as to help developers greatly reduce the time of hardware connection and on-board debugging

, Even at home, you can analyze software code at any time , Make device development more convenient and efficient . 

Specific usage ：：

• Click Import project  >  Select the project path and OpenHarmony After the source code, click OK >  Choose products 、MCU、 Development board and OpenHarmony Click open after the version number .

• And then click build Compile .

• Finally, click run Start downloading simulator components , Click again after downloading run Button , Image transmission , After the image is transferred, the simulator can be run .

Refer to the official website link for the debugging operation of the simulator ：

5、 ... and 、 Enhance debugging ability

In the development process , Debugging ability is particularly important , A useful debugging function can help developers get twice the result with half the effort .DevEco Device Tool The following debugging capabilities are enhanced on the existing debugging functions ：

• View the assembly context according to the assembly address , Provide quick opening disassembly interface 、 Search disassembly address 、 Search functions and support quick switching between disassembly and source code .

• Memory calculation based on offset address is supported , Provide the starting address , offset , Length can calculate the memory .

• Memory view is supported, and each line is arranged by bytes .

Specific usage ：
