This page has been verified with the following versions of software tools: You can set breakpoints, examine variables, and debug the hardware as you normally would. The IDE will connect to the hardware, load the bootloader, wait for it to enter debug mode, then load the Harmony application into DDR and execute it. In this example the J-Link and XC-32 v2.41 are used. Select the correct HW debugging tool and Compiler. Right click on the project name and select “Properties”.

Now that the autoload.py and bootstrap are in place, we can use MPLAB X to download and debug our Harmony application. Now copy the boot.bin file from the AT91Bootstrap build done previously to the same directory where the autoload.py script is. Note that for the SAM9X60 the entry_addr is 0x23f00000 and the bootstrap_entry_addr is 0x300000. To start, pick the defconfig for your board that runs out of some NVM, like an SD card, e.g. If your board doesn’t already have a defconfig, not to worry, we can easily create one. Look for a defconfig with the name bkptnone in it, e.g, sama5d2_xplained_bkptnone_defconfig. Some of our existing boards already have a defconfig for use with MPLAB X. For now, we’ll just focus on only the configuration changes needed to build an image for use with MPLAB X.

The github page for the bootloader has instructions on how to configure and build on both Windows and Linux platforms. To make development easier, rather than loading the AT91Bootstrap and Harmony images into NVM, we can use MPLAB X to load both the bootloader and application via the debug interface (e.g. The AT91Bootstrap initializes clocks, PIO, and DDR prior to relocating the application image from NVM to DDR and starting it. Harmony uses the AT91Bootstrap as its second stage boot loader. The SAM MPU’s, like the SAMA5D2 and SAM9X60, have a ROM based boot loader that looks for a second stage boot loader in external NVM, relocates it to internal SRAM, and executes it.
