Hi.
Tested some images. Each image, that is able to record, contains the pau in /usr/bin/ and it's init script in init.d!
pau itself is closed source, so no chance to find the sources.
Using pau from another image doesn't work (look post up).
By the way, original image doesn't contain a pau.
Best regards
Mike

open("/dev/bcm_au", O_RDWR) = -1 ENOENT (No such file or directory)
It looks for /dev/bcm_au ...
Posted 7 January 2015 - 14:15
~# ls /dev
bcm_au
but copied pau from oe-alliance or from another image is not executeable on my solo se
due to ELF error.
What I'm doing wrong?
Posted 7 January 2015 - 14:15
chmod +x ?
Posted 7 January 2015 - 14:25
of course chmod +x
readelf --symbols pau:
readelf: Error: Unable to read in 0x550 bytes of section headers
So is's definitely the binary
Posted 7 January 2015 - 14:32
Maybe binary corrupted? You can download from github directly https://github.com/o...au/pau?raw=true
md5sum pau f3c9619098980c1772415e6d8e823b61 pau
Posted 7 January 2015 - 14:37
~# ./pau
: not found 1: ELF0
./pau: line 2: syntax error: unexpected word (expecting ")")
size of that pau differs from size of the openvix pau

hmmm strange behavior:
If I copy a binary from my solo via filezilla to my debian system and the back to my solo teh binary isn't executeable anymore, even if I do a chmod +x.

Maybe you do ascii transfer? It worked here.
Posted 7 January 2015 - 17:52
@malakudi: you're the big boss!
I'm using debian sid and during last compilation of filezilla ftp switched to auto (I didn't realize that).
After switching to binary all works as excepted.
But it's time for a little bit reverse engeneering.
In the meantime I've different versions auf the pau binary.
All of them uses
librt.so.1
libstdc++.so.6
libm.so.6libgcc_s.so.1
libc.so.6
One of them contains 550 unreadable bytes (I don't know to handle that).
The pau from the post up instead contains crypto calls:

Again you're wellcome for the "transfer option"....

I think it is a little silly to disable this option in the drivers and then release a utility that enables it. If they go to court for tax fraud, I bet no judge will believe them that the utility pau is not from them. So they better stop this nonsense.
As an EU citizen I also find it quite disturbing for a big company to try avoid taxes.
Posted 8 January 2015 - 09:37
I agree, but I'm not shure about pau. There are to much different versions. As far as I analyzed that tool it's the only ambition to provide a key for the soc.
I didn't analyze the other vu duo images (yet) if they contain a pau, too.
By the way, the info about the oe-alliance git was well. I did a git clone, because there are many usable "things" in there.
Bye

Yes,; it's a pity PLi & OE-A don't have a bit of cooperation. Would be of mutual benefit.
Posted 8 January 2015 - 13:18
So why isn't it there? We don't block any cooperation.

You know the story very well yourself.
Posted 8 January 2015 - 15:39
No.
We are open to cooperate with anyone. And we accept code from anyone. The only thing we require is that our standards are adhered to.
If you are suggesting otherwise, you are wrong.

You know I'm not suggesting anything.
And 'accepting code' isn't the same as cooperating. But that's the end of me going off-topic: you know the full story very well indeed.
Posted 8 January 2015 - 16:25
Why do you always cut discussions off when it doesn't suit you? And go on and on as like a broken record when it does?
You know very well why we don't let OE-A dictate how we operate, exactly because of a difference in opinion about standards.
So again, where are we a blocking factor in cooperating with anyone else?
