Hey everyone! If you are looking for concise steps to create and apply a patch in a yocto build, this article will serve you well. The reference taken in this article is of iMX93EVK yocto build. For this exercise, we are modifying a lpspi dts file in the BSP and creating a patch file but you may apply the same steps to other files in the BSP as well. Step-1 Make changes to the dts file in your directory example - arch/arm64/boot/dts/freescale/imx93-11x11-evk-lpspi.dts Step-2 In your yocto build, go to the git folder  cd imx-yocto-bsp-home/build_11x11/tmp/work/imx93_11x11_lpddr4x_evk-poky-linux/linux-imx/6.1.36+gitAUTOINC+04b05c5527-r0/git Step-3 Execute 'git diff' to check the difference between your changes and the default ones    Check the status by executing 'git status'     Step-4 Execute 'git add <file>'  , 'git commit -m <message>', and 'git format-patch -1' to add a file and create a git format patch file for your changes.   copy the generated patch file to a location which yocto build look for the patches Example- My yocto build looks for the patch in various locations, one of them is this one :- sources/meta-imx/meta-bsp/recipes-kernel/linux/files, so after creating the directory 'files', we can move the patch file to this folder    Step-5 Edit the .bb file for linux recipes-kernel for example - Open  /home/nxg06361/imx-yocto-bsp-home/sources/meta-imx/meta-bsp/recipes-kernel/linux/linux-imx_6.1.bb  for editing Append the patch file name to the SRC_URI variable     You can also verify that your patch has been successfully applied or not by doing 'git log'   Voila ! that's all you need to do in order to create and apply a git patch for your yocto build.

This document describes the manual conversion of a (CodeWarrior MCU 10.6) Processor Expert project by creating of a new project in KDS 3.0.0 for the same target MCU and copying of Processor Expert project and user source code. This options of the CodeWarrior (or Driver Suite) project conversion provide an easy way how to convert the project but all customized settings of compiler, linker and libraries must be set manually in the new KDS 3.0.0 project again (this configuration will not be migrated). The migration of the whole CodeWarrior project is described in the document CW MCU 10.6 Processor Expert projects migration into KDS 3.0.0 Steps: 1. Create a new Kinetis project for the same target MCU (navigate to menu File > New > Kinetis Project). Write a new project name (you can write the same name of the original project). Select the same target MCU (or a target board that use the same target MCU). Kinetis SDK – select None Check Processor Expert Select the compiler that is available (installed) in your KDS 3.0.0 installation (GNU C Compiler is available by default). 2. Remove all Processor Expert components from the project (delete all CPUs and components if included). All components will be imported from the original project. 3. In the Components windows, navigate to the View Menu > Import > Import Processor Expert Component Settings 4. In the Import Processor Expert Component Settings windows, click on Browse button 5. In the dialog, select *.pe file extension and select the ProcessorExpert.pe from the original CodeWarrior Processor Expert project. Click on the Open button. 6. In the Import Processor Expert Component Settings windows select the target project (the new project). 7. The window contain list of all components that can be imported (added). You can select components that can be omitted (all will be imported by default). 8. Click on the Finish button. All selected components are imported and no warnings and errors should be reported. 9. Open the folder with the original CodeWarrior project and drag-and-drop source code files (copy files) from the  CodeWarrior project into the new project created in KDS (select Copy files).   Please note, that CodeWarrior projects have the main() function in the ProcessorExpert.c file but the Kinetis Project uses the main.c (copy the content or you can rename the copied ProcessorExpert.c file) . 10. If necessary you can customize the project settings of the project by using Properties (in the Project Explorer window open the context menu of the project and select Properties). You can select the settings that are required by your application (optimization level, adding path to external libraries and so on). 11. Generate the Processor Expert code and Build the application. When all source code is copied (and customized settings and paths are properly set) the application is compiled without any errors and warnings. Debugger connection are pre-configured in the new Kinetis Project in KDS 3.0.0 by default.

Remember Processor Expert? Just to refresh your mind, is a development system to create, configure, optimize, migrate, and deliver software components that generate source code for Freescale silicon, supporting S08/RS08, S12(X), Coldfire, Coldfire+, Kinetis, DSC 56800/E, QorIQ and some other Power Architecture processors. And well, what's the such new great thing in it? Take a look: Microcontroller Driver Suite v10.0 is a software management system to perform Processor Expert's tasks and provide a low-cost, efficient solution for your designs. Just recently a great update has been made into it: the driver suite is delivered and installed as a comprehensive product with the Eclipse 3.7 (Indigo) IDE. It is also available as an Eclipse 3.7 plug-in. This extends Processor Expert software functionality to non-CodeWarrior IDE users for the supported platforms. The cool, useful part of all this is that Processor Expert technology packaged in the driver suite makes it much easier to optimize the low-level intricacies of a hardware platform. It also eliminates the necessity for one-size-fits-all drivers, therefore the driver suite allows you to design custom peripheral drivers ideally suited to your needs, without the need for extensive hardware knowledge! And just as aesy as that, you get a whole new set of possibilities to empower your design! You can try the software by just clicking here Microcontrollers Driver Suite v10.0 And you can also get the Driver Suite for Eclipse by clicking on here Microcontroller Driver Suite v10.0, for Eclipse 3.7 (Indigo)

Since I want to use some settings of the provious project, I find there are two ways which both don't work. I select the "The LCD"  example project which locals in"\\\Freescale\CW MCU v10.3\MCU\CodeWarrior_Examples\Processor_Expert\Kinetis\TWR-K40X256\LCD". First gererate code,  build and run the project with success. Then I save the processor setting as template and add  it in a empty PE project from the "Component Library", Generate Processor Export code with error "Incorrect Tool Chain Select", I check the new project propeties and change the "Current toolchain" as "ARM  toolchain"  in correpondence with the previous project.  Regenerate the code , there still exit 9 errors in the _arm_start.cfile . Description Resource Path Location Type Undefined : "exit" __arm_start.c /PE_use_template/Project_Settings/Startup_Code line 287 C/C++ Problem Link failed.

Can anyone give some hints or advice to this problem?:D
