Dfu-util
Updating firmware with dfu-util
You will need
dfu-util 0.5 or newer to download dfu files to the DSO Nano. Older
dfu-util versions will not work. The DSO Nano, and many other devices
based on ST Micro's microcontrollers, uses ST Micro's own DFU extensions
(DfuSe) which are not compatible with the DFU standard.
You can
find a dfu-util 0.8 package for Ubuntu 10.04 in Tormod's PPA. Just
download and install the right .deb package. The same package should
install fine in any later Ubuntu version or Debian unstable as well. For
other operating systems you may have to build dfu-util yourself as
described at the dfu-util home page.
To download a .dfu firmware file from your computer to your Nano, run this command
dfu-util -a 0 -D your-firmware-file.dfu
You
might have to rerun it a couple of times until it succeeds. If you get
"permission denied" errors, prefix the command line with "sudo ". Do not
forget to repeat the command with all needed firmware files (APP and
LIB).
Downloading a non-dfuse file to a dfuse device (advanced)
A
standard DFU device will accept a raw binary file from the computer and
load it into the right place in flash memory. On the other hand, with
DfuSe, the addresses are given by the .dfu file and the computer has to
tell the device where to load it.
So to download a raw binary file to a DfuSe device you have to know the target address.
Example, to download a raw binary file (in case you are developing):
dfu-util -a 0 --dfuse-address 0x08004000 -D your-lib.bin
dfu-util -a 0 --dfuse-address 0x0800C000 -D your-app.bin
