2.2.2 AM261x USB Application Example

Figure 2-3 shows how the AM261x acts as a USB device running the DFU application. The DFU functionality can be used to update the firmware binary via USB in field. This means, there will be no down-time and enhanced firmware can be loaded to the MCU. The host machine having the USB host runs a dfu-utility program. This program is used to send files from the host PC to the AM261x device acting as USB device.

More details about the dfu-util commands can be found here: AM261x MCU_PLUS_SDK USB DFU example.
