If the bootloader for your board should not be available you can simply dump it into a binary file also using the J-Link Commander and the command savebin.įor more information see our J-Link user manual. If you want to revert the Arduino board to its original state you need to flash the Arduino bootloader of the corresponding board you are using.įor this the now established connection between your J-Link and the board can be used.Īs a tool we recommend using J-Link Commander where you can use commands loadfile/loadbin to flash the bootloader file. Note: Using this example project will erase the Arduino bootloader and allow bare-metal debugging of the target device. It is a simple Hello World sample and can be downloaded here: The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the Arduino Due board. You can set Ozone to attach to the target device via Debug->Start Debug Session->Attach to Running Program.īare-metal Debugging Example project for SEGGER Embedded Studio We recommend using Ozone, the J-Link debugger as it offers the best debug experience with SEGGER debug probes. ![]() Now you can launch your favorite debugger with J-Link and attach to the running application and debug your system.Arduino IDE via the USB-Interface as usual. Download your Arduino Sketch with e.g.Connect your board to a J-Link as explained above and test the connection with J-Link Commander.But if for some reason you can't use that method you can still debug as follows. Generally we recommend the direct debug approach as shown above. How_to_debug_Arduino_a_Sketch_with_Ozone_and_J-Link Indirect debugging of the Arduino sketch Im doing a project where in Im using Arduino Due to measure the time difference of arrival of signals to four piezoelectric sensors. How to debug your Arduino sketch directly is explained here: Generally there is two ways to debug a Arduino sketch with J-Link. Power the board via one of the USB-Mini ports.This function will change the state of the LED each time it is called. Next, we will create a function to blink the LED. The following picture shows the LED blinking program using the Arduino Due timer interrupt. ![]() The resulting connection will then look like this: The Arduino Due sends high signal and low signal at interval of 500ms which is controlled by the interrupt service routine(ISR). In this example we are using a J-Link Plus Compact. ![]() If you are using the full size or compact models of J-Link the 9-Pin Cortex-M Adapter can be used. A way to connect to the 10 pin debug connector of the Arduino Due boardĪs the Arduino Due board comes with a presoldered 10-pin debug connector labeled JTAG all you need is a connector/adapter for that interface.4.1 Example project for SEGGER Embedded Studio.3.2 Indirect debugging of the Arduino sketch.3.1 Direct debugging of the Arduino sketch.
