Download this OpenOCD configuration script to your project directory.Change the linker script to the “xxxx_ram.ld” version:.Open the MSBuild Settings page of VisualGDB Project Properties and locate the linker script: In this tutorial we will switch the program to run entirely from SRAM in order to demonstrate CMSIS-DAP-based debugging. Note that CMSIS-DAP is relatively slow and as of January 2019, the OpenOCD tool used to debug the board with it cannot program the on-board FLASH memory unless you create a FLASH programming plugin. Now we will show how to use the on-board CMSIS-DAP interface instead of Segger J-Link. ![]() As the imported project includes all the necessary code from the SDK, you can use the CodeJumps popups to explore relations between different parts of the program itself and the i.MX RT SDK: You can use the regular debugging techniques to debug your program.Set a breakpoint near the GPIO_PortToggle() call and wait for it to trigger:.Verify that the on-board LED is blinking: Now you can build the project by pressing Ctrl-Shift-B:.Select “Segger J-Link” on the Debug Method page and click “Finish” to generate the project:.Connect J-Link to the 20-pin JTAG connector and plug both J-Link and the board into the USB ports: It comes with out-of-the-box support for on-board FLASH memory programming and is much faster than the on-board CMSIS-DAP interface. The easiest way to debug the i.MX RT devices would be using an external Segger J-Link device. The last page of the wizard allows configuring the debug interface.In this tutorial we will use use the “igpio_led_output” example: Click “KSDK Samples” to view the vendor-supplied samples instead. As the SDK was imported automatically, it won’t contain any VisualGDB-supplied example projects.VisualGDB will import the SDK and display the i.MX RT devices in the device list.Point VisualGDB to the folder where you have extracted the generated SDK:.On the second page of the wizard click “Import an MCUXpresso SDK”:.On the first page of the wizard select “Create a new project with MSBuild”:.Extract the downloaded SDK anywhere on your computer and open the VisualGDB Embedded Project Wizard:.Confirm your OS/toolchain settings (GCC ARM Embedded) and click “Download SDK”:. ![]() Open the MCUXpresso online SDK builder, select your board and click “Build MCUXpresso SDK”: Instead, you need to generate an SDK for your board online. ![]() The i.MX RT devices do not come with a regular stand-alone SDK.We will create a basic “Blinking LED” project for the IMXRT1050-EVB board and will show how to debug it using Segger J-Link and the on-board CMSIS-DAP-compatible interface. Before you begin, install VisualGDB 5.4 Beta 2 or later. ![]() Under SEGGER's Friendly License, Embedded Studio is available for unlimited evaluation, and for educational and non-commercial purposes, free of charge, with no restrictions in terms of code size, features or duration of use.This tutorial shows how to create a basic project targeting the i.MX RT device using Visual Studio and VisualGDB. One IDE fits all!”Įmbedded Studio's built-in debugger natively supports J-Link, ideal for automated testing and, with its integration of the GDB remote protocol, also enables the use of third-party debug probes. We continue to keep our products cutting-edge and multi-platform for everything from small microcontrollers up to devices with multiple Arm Cortex-A 64-bit cores. “This makes support for Arm64 important for our customer base. "We see a migration to 64-bit cores, even for a typical embedded application, simply because many modern SoCs and FPGAs use them,” says Ivo Geilenbruegge, Managing Director of SEGGER. In combination with the highly optimizing C/C++ SEGGER Compiler, extremely small yet efficient programs can be generated, putting every byte to work. It comes with SEGGER’s highly optimized emRun runtime and emFloat floating-point libraries, as well as SEGGER's smart Linker, all of which have been developed from the ground up specifically for embedded systems. With a similar look and feel on all platforms and fully portable projects, developers enjoy efficient development on Windows, Linux, and macOS, on Arm, Intel, and Apple Silicon.Įmbedded Studio includes all the tools and features needed for professional embedded C and C++ programming and development.
