That would probably be better than TFTP over ethernet. A USB DFU upgrade would only require the microcontroller to be functioning for the upgrade to work and it doesn't require TCP/IP stack or ethernet chip drivers. I maintain a family of devices which can be built with or without ethernet. Currently we attach an ethernet daughterboard to the device to bootstrap it, and for development, but remove it for commercial use. We are planning on using a PEEDI JTAG for production installation and I have been working with the PEEDI developers to get UBI/UBIFS support into the PEEDI (currently supports JFFS2). JTAG is good for production installation but USB DFU is ideal for field upgrades or bricked-system recovery.
