Let me try to explain it in simpler terms: So it will work out of the box! The link isn't a mistake. The Sam-chip will come preloaded with a bootloader. There is no bin file that needs to be uploaded. I am also making my own Due and am a little stuck on this step. bin file that needs to be uploaded to the SAM chip?Īlso, I think in your post above you posted an incorrect link by mistake, referring to using Arduino's bossac tool. I have a question: can you please point to the. What I did is add a external script that programs the chip after compilation. I use Atmel Studio sometimes with this chip. NOTE-2: Yes, you can program the chip with Atmels SAM-BA program. If you press it, the chip will be whipped and you'll have to do the process all over again (choosing the SAM-BA drivers etc etc). NOTE: Regarding the hardware erase switch. Just program it with the option Arduino Due Native port (The bootloader will do a soft erase each time it flashes the chip). After programming the USB will remount as the Arduino Due in which case you'll have to point the driver wizard to the arduino drivers located somewhere in the arduino ide folder.Īfter that it's simple really. To program it just go through the normal process through the arduino IDE(Select Arduino Due Native Port in the boards menu). The first time you plug in the board it will present itself as AT91 USB to Serial Converter (use the drivers that comes with the SAM-BA program). Well, you program it through the USB native port. Getting fluctuations from the power supply/circuitry can lead to the USB connecting and disconnecting randomly. The caps are important specially for the USB communication. So what's the programming process w/ the USB attached directly to the MCU? Erase program w/ the button, then hit reset and upload via arduino user interface or what? Can you just upload a hex file with another program instead? A lot more capacitors than I anticipated, and I wasn't sure if both crystals were necessary myself. Īnd by the way I've changed a small thing in the schematic so here is the updated version: After install you should get the following.
The board will restart as Arduino Due (you'll need to install the arduino due drivers that comes with the arduino IDE). Then open Arduino IDE and upload the blink sketch.
After installing the drivers you should get the following: When you attach the USB the first time, you need the drivers delivered with SAM-BA.
After two hours of trying to fit the break out (made wrong measurements) board to my newly soldered board it's finally working.īreakout board attached to the board (Front): It was probably noise from the breadboard. To all of you, yes it works now :D:D:D:D.
