Hello,

What tool did you acquire memory with?

Something like jtag debugger.

Hello,

Would it be possible to send the memory sample you acquired or is it senstive? 
I can give you credentials to a private FTP server only used by the developers, 
it would not be made public.

It's under strict NDA. So all what I can - try patches from you and send debug 
logs back.

Andrew, can you provide an update on this issue? Are there some patches you can 
send Vitaly to help debug?

Hello Vitaly,

Do you know if there is public documentation of how the jtag interface is 
acquiring RAM? I read about trace32 and it seems to run against live systems. 
From looking at the output of -dd it shows that the ARM profile is selected, 
but then pslist falls apart. This means that the initial (static) translation 
is correct, but the dynamic ones are not. 

I have a feeling the memory dump is in a format that does not pad output so 
that the offsets retrieved from address tralsnation are wrong. On the live 
system could you run 'cat /proc/iomem' and paste the output here (or email to 
me if its sensitive)? This will help me figure out how RAM is laid out in 
physical memory.

Hi Vitaly, 

You can get Andrew's email from the tracker (its just atcuno [at] gmail.com) 
and mine is michael [dot] hale @ gmail.com. Feel free to shoot us an email when 
you get a chance to run cat /proc/iomem and we can help you troubleshoot 
through the issue. I'll close the issue here, because it sounds like some info 
shouldn't be discussed publicly. Thanks!
