Hi, I've been searching everywhere and I can't find an answer to this. I am planning on designing a custom board with the sam3x processor and I'm attempting to program it with the raspberry pi. I can program the due with the bossac gui in ubuntu no problems via the usb ports, but I eventually wanted to ditch the 16u2 interface and go directly into the first uart (Tx0 & Rx0). I pulled out the datasheet on the sam3x and my understanding is that if I press the erase button, the sam3x should boot into samba which looks for programming on the native port or uart, is that right? Bossac doesn't even recognize the due this way.
Any questions or if I've left any important info out please ask and any ideas would be helpful. Thanks.
