HP/Agilent 1675x logic analyzer card memory up-hack
Hamster:
From my understanding, these cards could be field license upgraded.
For Example here are the .lic files for my cards ( I have masked the Serial # and the last could of digits of the signage )
#START LICENSE INFO
FEATURE 16911_250MHz_State agilent 1.0 permanent uncounted HOSTID=ANY SN=MY44000XXX SIGN=B16B8826xxxx
#END LICENSE INFO
#START LICENSE INFO
FEATURE 16911_4Meg_Samples agilent 1.0 permanent uncounted HOSTID=ANY SN=MY44000XXX SIGN=5B56C2D8xxxx
#END LICENSE INFO
^^ that card that had the 4Meg Samples still has the 256K memory sticker on it ^^

For all those that need to recover licenses for the Agilent 168x(x)/169x(x), attached is the "secret sauce".
It has been tested with the above licenses and should work with all others.

Hmm, So what is Seed1 and Seed2 ? and i assume the Vendor is the Feature?
Also, the u90 eeprom data:

Are those the Seed1 and Seed2 values for the 16700 series analyzers, not the 16900 series analyzers?
What do you do with that information? I have seen images of the "Generic FlexLM Crypt Generator v0.5 by Haldir" posted in other threads on the eevblog forum, but have never found any references to that anywhere else on the net. Where can a copy of that tool be found?
Hamster:
gslick, so, looks like that is a key gen for the Flexeria LMUTils .. and looking at the LA software, it def uses it, i sent all my keys to him and he did verify the key gen..
So its just a mater of figure out the feature codes.. I am assume the 16911 32M feature key is: 16911_32Meg_Samples
The Serial Eeprom only holds the Serial # and 3 extra digits.. i am betting those 3 digits are just option flags. and lmutil decodes the feature key and then updates the Serial Eeprom ( or tells the LPA Service )
as once the feature is enabled, it travels with the card.
