Using dfu-util to upgrade firmware on attached USB device

[kjetil-fleten]

Hi

I'm trying to update my sons internet radios firmware from one of our Ubuntu computers; we have 5 Ubuntu, no Mac and no Windows in our household :-)
The radio can be upgraded via USB, and I have installed dfu-util for the purpose.
When I connect the radio to the PC in download mode, I can see that the radio is connected, but I can't upload firmware because dfu-util tells me there is to many attached devices. There is only one, and thats the radio. I get this ouput:


$ dfu-util -l
dfu-util 0.5

And the failure message itselves:

More than one DFU capable USB device found, you might try `--list' and then disconnect all but one device

Any idéas how I can tell dfu-util which DFU entry to use ?
Or how to remove all the extra DFU's from the same device ?

Ok, I found the problem.
Here is the solution, if anyone else runs into the same issue:

First, it helps to use the commands with sudo ;-)
(http://community.spark.io/t/dfu-util-cant-list-address/889/8)

sudo sudo dfu-util -l gives

dfu-util 0.5

Found DFU: [1d50:5119] devnum=0, cfg=1, intf=0, alt=9, name="rootfs2"



Then address the firmware files to the right Altsetting. In my case, the Internet Radio is a Sagemcom RM-50 with 3 files:

sudo dfu-util -a 5 -D RM50/zImage-RM50-YD3-V0.45-P-20121210-204454.img1
sudo dfu-util -a 8 -D RM50/rootfs1.squashfs-RM50-YD3-V0.45-P-20121210-204454.img2
sudo dfu-util -a 9 -D RM50/rootfs2.squashfs-RM50-YD3-V0.45-P-20121210-204454.img3

Now it works !
