bossac.exe --port=COM1 -U true -i
Hello kingmail,Bossac is not only a boot-loader tool for the SAM3X8E but supports all of Atmel's known flash-based SAM devices. I believe bossac checks automatically the CIDR of the MCU. Just try:I used comm. port 1 as an example. Remember to change to your current COM port.Also change to 'false' if your are connecting to the USB-to-TTL serial chip.You should program your sam3x8c using bossac in the same way you do it for Arduino Due.Anyway, I have a 3x8c system at home and I can try some tests tonight.Regards! EDIT:<< Do not use the Arduino IDE to compile/program your SAM3X8C based board at least you have the variant files redefined for the 100-pin package of SAM3X8c. I am not sure about the uart interface settings but may be you will need to redefine them too.I would recommend you to use Atmel Studio 6.1 where you can create bare minimum project templates for the SAM3X8C which will automatically generates the 100-in/out pins and other utily files. Just let me know where you are in your project (stage).You can always count with the at91 Atmel tech support team after generate a ticket. >>
Hello duramaxhd,Can you elaborate a bit more your question? For example, will the variant files that you need work with a third-party board? or it is your own design?Are you planning to have the variant files available into Arduino IDE? or another environment like Atmel Studio?I am asking this because adding or updating variant files based on SAM3X8C is not a big deal but it will depend on your hardware and IDE.In case you have a third-party board, you can generate generic variant files from Atmel Studio that work for it and customize them to the I/O pin definitions (LEDs, buttons, etc.) of the real board. In case you have your own design, another option is to fork in github to introduce your board and present basic variant.h/cpp and pin_arduino.h files, so that others can help you on this.Finally, a third option can be to contact directly Atmel SAM-based tech support team (I don't know if they are Microchip now). Good luck.-p
