Legic Prime problem?

Sorry for my bad English but I try to explain the problem..
I have implemented (as I hope) manually the fork from icemann1001 and as the problem concerns legic (???) I choose this forum.
At first as I implemented the fork there where some trouble and got some errors. I solved the problems??? by copy the legic.lua (and the other legic files)  in the proxmark/scripts and the utils.lua in the proxmark folder.
I would read cards with a legic prime 1024 chip with the lua script “legic”(rt). But now I always get the following error:

C: \Projects\Proxmark\utils.lua:93: attempt to call field ‘crc8legic’ (a nil value)

Also with the legic_clone.lua. I tried this with several SAM Cards but I got always the same error.
One SAM card I can read without an error but I don’t want to clone this card
For example the CDF of one card:
CDF: System Area
MCD: 41, MSN: 0a b7 d2, MCC: 4d
DCF: 60 ea, Token_Type=SAM (OLE=0), Stamp_len=18
WRP=15, WRC=1, RD=1, raw=9f, SSC=ff
Remaining Header Area
00 00 00 11 04 1e c0 08 40 5c 90 00 00
I will try to solve the problem but if anybody can help me than feel free to do it

The recommendations is to use the compiled fullimage, client and scripts from the same fork,  otherwise you will most likely open a can of worms.

and in addition to Iceman ...
there are a lot of 3rd-party systems out there ... the layout on the card that works, is close to what I have had in my hands as I wrote the script, but it might produce some errors on unknown tag-formats (like this one - per example)
so, you should start with the 'hf legic read/load/save' and 'data hexsamples' functions

Re: Legic Prime problem?

OK?
I downloaded the pm3-bin-2.5.0 windows client form proxmark.org and unzipped the win32.. in the “proxmark” folder.
After them I download the fork from iceman:
https://github.com/iceman1001/proxmark3
and then I copied manually the files and folders in the “proxmark” folder.
Is that the right way?

@mosci: I had done this. I can read and save the data of the cards. But if I write back to a blank card then I get always a mistake:
#db# operation aborted @ 0x018
Then, in my simple opinion, I found the legic.lua and I thought this would be easier (CRC…) …

I continue to try….

Re: Legic Prime problem?

just coping the files will not do the job.
you will have to build it from the source and upload the (full)image to the PM3
