Rm -f $(OBJS) $(OBJS.o=.d) $(ELF) $(CLEANOTHER)Īrm-none-eabi-gdb -iex "target extended-remote localhost:3333" $(ELF) If you have another board, it may have LEDs on a different PIN or not at all, you need to adjust the code below (for example, SAMD21 Xplained pro has an LED on PB30). We will make it blink to test our settings. The pin of the Sparkfun SAMD21 breakout board is marked with a "D13" LED, which is mapped to GPIO PA17: the 17th io port on port A. If you run to this point, OpenOCD has been completed. Type "apropos word" to search for commands related to "word". Type "show configuration" for configuration details.įor bug reporting instructions, please see:įind the GDB manual and other documentation resources online at: This GDB was configured as "-host=x86_64-apple-darwin10 -target=arm-none-eabi". ![]() There is NO WARRANTY, to the extent permitted by law.

Info : at91samd21g18.cpu: hardware has 4 breakpoints, 2 watchpoints If you start OpenOCD again, you should get the following output: Don't forget to power the Atmel SAMD21 board separately, such as USB. Now you can insert the SWD header in the board to be programmed. Info : SWCLK/TCK = 1 SWDIO/TMS = 1 TDI = 1 TDO = 1 nTRST = 0 nRESET = 1 Info : CMSIS-DAP: Interface Initialised (SWD) Info : auto-selecting first available session transport "swd". You only need to type openocd to test the openocd.cfg file. You should change the value 91SAMD21G18 to match the microcontroller you are using. # Atmel-ICE JTAG/SWD in-circuit debugger. To do this, create a file called openocf.cfg with the following content: On Debian Linux, you can use a command similar to aptitude install openocd.Īfter installation, the next step is to set up OpenOCD correctly. ![]() Installing OpenOCD on Mac is also a line of code: On Linux with a Debian-style operating system, you need to refer to your package manager (apt-get or aptitude). On a Mac, using homebrew, it boils down to one command: The ARM developer tools (arm-none-eabi) need to be installed on the system. If you try one direction but it doesn't work, just flip the connector! Step 2: Install C compiler for ARM Since the connector is not locked, there are two ways to insert the Atmel ICE into the circuit board. Then, you will insert the corresponding connector on the Atmel ICE. You don't necessarily need to solder the plug to the circuit board: usually you only need to insert the plug to ensure good electrical contact. You need to install a 2x5 pin 1.27mm male header on the right side, as shown in the figure below. On the Sparkfun SAMD21 breakout board, the SWD plug is present but not soldered, as shown in the figure below, on the left. To use OpenOCD to program the SAMD21 board, you need to connect the programmer to your development board using the SWD plug. On Mac, we recommend using homebrew to install the different tools described here. On Debian Linux, use your package manager (such as'aptitude'). You need to install some software packages to program the SAMD21 development board. In terms of hardware, this article also assumes that you have an Atmel ICE Programmer. It uses the popular Atmel SAMD21G18, and our example should be modified with little or no modification on similar platforms, such as Arduino M0 or TAU. To illustrate the way to program SAMD21 MCU, we will use Sparkfundev breakout board as our target. This article mainly describes how to use Atmel ICE to program the SAMD21 microcontroller, using the command line on Mac OS X or Linux Debian systems, without Atmel Studio or any other IDE, or even any hardware abstraction library.
