I did the memory dump under Linux because that was what was shown in the tutorial post (page 163 of the sniffing the I2C bus thread) and also I saw some reports of people having problems using Windows to do the dump. I have had no prior experience of Linux but did not find it too difficult.
I used 'Universal USB Installer' (UUI) to make a boot USB pen drive. XUBUNTU was selected for the distribution and I set a reasonable value for the persistent file size. The blackfin tool chain file I used was blackfin-toolchain-2013R1_45-RC1.i386.tar.bz2.
In order to boot from the USB stick I had to change the BIOS boot mode setting on my laptop to CSM.
The link to USB Blaster I used is
USB Blaster.This uses a Silabs F321 and a 74LCV125 chip.
When the dump starts the scope will become unresponsive.
It took about three hours to get the dump but it may have been slowed down by running from USB stick.
There are two bits of software you have to run at the same time, a proxy application that works as a server and the client application. To open the terminal windows I just navigated in the file explorer to the directory and right clicked on the directory and selected open terminal here. You will need to read page 163 of the sniffing the I2C bus thread to get the details of the commands.
While the dump is taking place you will see a log as each section of the memory is dumped.
The resulting .bin file that is stored in the home directory was then copied on to another USB stick.
Using a Windows PC copy the dump file to the rigup directory and use the rigup program: rigup ds2072a DumpFile.bin (replace Dumpfile.bin with the name of the file you used).
The rigup program will now give you the keys you need.
The following shows the use of rigup:
rigup ds2072a DumpFile.bin
rigup ds2072a - Version 0.4
Serial number: DS2F162XXXXXX
NSEH: XXXXXXX-XXXXXXX-XXXXXXX-XXXXXXX All options, no bandwidth upgrade
NSER: XXXXXXX-XXXXXXX-XXXXXXX-XXXXXXX All options, bandwidth 100 MHz
NSEQ: XXXXXXX-XXXXXXX-XXXXXXX-XXXXXXX All options, bandwidth 200 MHz
NS8H: XXXXXXX-XXXXXXX-XXXXXXX-XXXXXXX All options, bandwidth 300 MHz
I then install the key directly from the scope by selecting utility - Option -Setup - Editor ON
When opening you scope you can avoid damaging the warranty stick if you follow mikeselectricstuff
