but where can I find the block with the fw file system.
How to read/interpret your listing, see attached file that I
cut & paste from your recent fw summary.

Oh, I see your problem!

The example that you provide is a SDS2000X file. Not a SDS2000X-E file!

This scope has a Blackfin proc and several FPGAs.

The X-E has an ARM proc. The structure of ADS is completely different, although the basic encryption envelope is pretty much the same.

You don't have a shadow file in the X version because it doesn't have a "file system" and/or linux environment.

Which is the equipment that you want to "analyze"?

markus_jlrb:
Oh,

what's a pity.

So I have to start to analyze from the beginning and
make my own experience and tools.

Thanks for your explanation concerning teh X and X-E
model suffix.

Markus

I think markus has misunderstood your question.

janekivi:
In other words, crypted-reversed-COR-ZIP files you must process to get files,
but in SDS1000X, SDS2000 and SDS2000X firmware you have plain files.
(except part 5 what is BlackFin app and bit obfuscated or so)
So those part 1...5 and 7 are the plain files what scope is using. I haven't given them names
but TV84 probably know better what files they are - FPGA, APP, ... (no LINUX there)
That's what SDS ADS files my SDS file viewer is made for. I haven't done repack utility yet...

markus_jlrb:
@janekivi,
@all,

make it sense to analyze the fw parts sds_ads tool generate with IDA-Pro?
And if so are there templates/addons/extensions that could be used for this
purpose?
