Overview

The REMCU CHIP SDK Collection is a comprehensive compilation of prepared Microcontroller Unit (MCU) Software Development Kits (SDKs) sourced from various chip vendors. These SDKs have undergone meticulous customization and adaptation to seamlessly integrate with the REMCU library on multiple platforms, including Windows, Linux, and MacOS.This collection empowers developers to remotely control MCUs from their PC applications using familiar APIs from the vendor SDKs made possible through the technology of MCU Peripheral Forwarding.

MCU Peripheral Forwarding

By leveraging the REMCU library, developers can seamlessly integrate the functions of the vendor SDKs into their PC applications. REMCU interrupts all peripheral operations, including storing and loading from registers, and executes them on the chip using OpenOCD or GDB server. This allows developers to conveniently and efficiently control the MCU's peripherals directly from their PC environment.

How to use

See remcu examples repo

It is highly recommended to use OpenOCD version v0.10.0-12 or v0.12.0-1.

Unix-like OS

Docker way

To facilitate cross-compilation for Linux and Embedded Linux, you can utilize Docker images specifically designed for this purpose. Docker provides a convenient way to encapsulate the build environment and dependencies, ensuring consistency across different systems. You can use pre-built Docker images or create your own. Here's how you can use Docker for cross-compilation:

  1. Install Docker: If you don't have Docker installed, follow the official Docker installation instructions for your operating system. Visit the Docker website (https://www.docker.com/) and download the appropriate version for your platform.

  2. Pull the Docker Image: Once you have identified the appropriate Docker image, use the following command to pull the image from the Docker registry:

    docker pull sermkd/remcu_builder
    
  3. Obtain the source code:

    • Clone the REMCU CHIP SDKs repository from GitHub using the following command:
      git clone --recurse-submodules https://github.com/remotemcu/remcu-chip-sdks.git
      
  4. Run a Docker Container: Start a Docker container based on the pulled image using the following command:

    docker run -it --name remcu-build-docker -v $PWD/remcu-chip-sdks:/remcu-chip-sdks -w /remcu-chip-sdks sermkd/remcu_builder
    
  5. Configure REMCU Lib:

    • Create a build directory:

      mkdir build
      cd build
      
    • Configure the build using CMake, specifying the your platform toolchain file: for Linux x64

      cmake .. -DCMAKE_TOOLCHAIN_FILE=/remcu-chip-sdks/REMCU/platform/linux_x64.cmake
      

      for Raspberry V1:

     cmake .. -DCMAKE_TOOLCHAIN_FILE=/remcu-chip-sdks/REMCU/platform/raspberry_pi_armv6_bcm2708.cmake
    
  6. To build a specific target, run:

    make <target>
    

    Replace <target> with the name of the specific target you want to build. For example, if you have a target named "STM8L15X_MD", the command will be:

    make STM8L15X_MD
    
    • To list all possible targets available on your platform, run:
    $ make help
    .....
    ... LL_STM32H750
    ... STM8L15X_MD
    ... LPC175X_6X
    ... EFM32TG840F32
    ... samd20
    ... MK64FN1M0VMD12
    ... XMC1100_series
    
    • To build all targets, simply run:
      make
      
      This command will build all the targets defined in the Makefile.

    After the build process completes successfully, the built library and tests will be located in the "output" directory.

    $ ls output
    ...
    STM32F030-StdPeriph_Lib-V1.5.0-01
    STM32F042-StdPeriph_Lib-V1.5.0-01

Troubleshooting

  • If you encounter error messages such as

       (ERROR)$#/#:207: Can't read value from addr: 0x40013008, typesize: 16
       (ERROR)$#/#:141: can't parse answer of server: [31] invalid command name "ocd_mdh"�
    

    during the usage of REMCU and the OpenOCD server, it is advisable to check the version of OpenOCD you are using. It is highly recommended to use OpenOCD version v0.10.0-12 or v0.12.0-1.

    Using the recommended version of OpenOCD ensures better compatibility and stability with REMCU. If you are unable to change the OpenOCD version for any reason, an alternative solution is to utilize the GDB server instead of the OpenOCD server. You can achieve this by utilizing the remcu_connect2GDB function to connect to the GDB server.

    remcu_connect2GDB("localhost", 3333, 0);
    
  • If you encounter an error message like:

    during the build process, specifically after the instrumentation operation using opt, it is recommended to check the versions of Clang and the ADIN opt tool. To ensure compatibility and avoid such errors, both Clang and ADIN opt should be version 8.0.0.

       $ $LLVM_ADIN_PATH/opt --version
          LLVM (http://llvm.org/):
            LLVM version 8.0.0svn
            Optimized build.
            Default target: x86_64-unknown-linux-gnu
            Host CPU: icelake-client
    
        $ clang --version
       clang version 8.0.0-3~ubuntu16.04.1 (tags/RELEASE_800/final)
       Target: x86_64-pc-linux-gnu
       Thread model: posix
       InstalledDir: /usr/lib/llvm-8/bin
    
    

    Mismatched versions of Clang and ADIN opt may result in compatibility issues and error messages during the build process. Therefore, it is crucial to ensure that you are using the correct versions to maintain a smooth and successful build
