Hello,

I have a firmware image from an oscilloscope from which I'd like to extract
the help texts to create a reference manual for our engineers. The firmware
seems to be compressed with a format called 'jzp' or 'jazip'.

Here is the header of the file :

00000000   69 6D 61 67  65 36 32 30  2E 6A 7A 70  43 50 00 02  image620.jzpCP..
00000010   00 00 00 18  EF 05 00 0A  AF 02 4A 41  5A 49 50 00  ..........JAZIP.

00000050   E8 B0 F4 F9  A0 08 28 02  0B 20 97 C0  20 92 2B 84  ......(.. .. .+.

Does anybody know if this is a common and open compression format, and where
I could find a decompressor ? Are there any legal issues when doing these
kind of things with somebody's firmware images ?

Regards,
