I mainly work with microcontrollers from the SAM4 series. So far, I've used a USB interface along with the SAM-BA tool for In-System-Programming. For a new project, a firmware upgrade via Ethernet should be possible.
I have read about the possibility to update the firmware via Ethernet on the SAM4S. For this an Android application is available to transfer the binary file to the microcontroller:
Is there such an application for Windows?
I'm also excited about other ways to update the firmware over Ethernet.
Thanks in advance,
