This shows you six interfaces, all in configuration 0 and interface 0, with

altsetting 0...4. The name is currently not yet defined, but will be added to

one of the upcoming u-boot releases. The mapping on the Neo1973 is as

follows:

0: RAM

1: 'u-boot' partition

2: 'u-boot_env' partition

3: 'kernel' partition

4: 'splash' partition

5: 'rootfs' partition

1-4-5 device function

You can specify the USB Vendor and Product ID of the device you want to

program:

dfu-util --device 0x1457:0x5119

If you only have one standards-compliant DFU device attached to your PC,

this is optional. However, as soon as you have multiple DFU devices,

dfu-util will detect this and abort, asking you to specify which device it

shall use.

1-4-6 transfer-size

Specifies the size of each individual USB transfer. If you don't use it, the

maximum possible size for your combination of host operating system and

USB device is chosen (for optimal performance).
