Legic_clone.lua // bad argument

[thebasti314]

I tried to use the Legic_clone script. The script crashed in line 231.

pm3 --> script run Legic_clone -i mydump.bin -d -s [+] Executing: Legic_clone.lua, args '-i mydump.bin -d -s'

read 1 bytes from mydump.bin /proxmark3/client/scripts/Legic_clone.lua:231: bad argument #1 to 'sub' (string expected, got nil)

Any ideas?

Looks like your binary file is very small..

read 1 bytes from mydump.bin

[thebasti314]

I checked it: the file is a binary and is 1024 bytes big. $ ls -lisa 3278259 4 -rw-r--r-- 1 root root 1024 Jun 4 05:53 mydump.bin

I would start looking at the script where it loads the file. It seem to some issue there

[iceman1001]

the script most likely wants a eml version of the file. It doesn't seem to load binary files. Try convert your bin -> eml

@uhei Maybe something more you can have a look at.

Already working on it (s. http://www.proxmark.org/forum/viewtopic.php?id=7710).

[iceman1001]

nice. I think I can close this issue since legic_clone.lua isn't in the repo any longer. legic.lua is the current script that is used.
