Subject: ads8272 SEC problem on 2.4.18
Date: Wed, 7 Sep 2005 11:20:25 +0200 [thread overview]
Message-ID: <BDEHJGPIKNLKJJBCCFPLCEOOCPAA.listuser@epygi.de> (raw)
HiHo!
I am trying to get the SEC engine running on a ads8272
but i am completely stuck now. (It feels like the problem
we saw on this list last month, but there is still no solution
to that issue yet.
Quick Problem description:
initialize seems, ok, yet when i feed a single
dpd (for DES EU) into channel 0, the engine
seems to stuck during fetch. Nothing happens.
Questions:
- Can someone help me out? (Not sure if this is the right list for this?)
- Do (open) sources for the SEC1 (motorola/freescale) engine exist for vanilla linux?
(I know of Arabella, but they are neither open nor for vanilla linux)
ciao
Markus
P.S. some more details below
--------------------------------------------
more info:
- i hopefully initialized it correctly
- prepared a dpd
- wrote it into fetch register
- see that something happens: CurrentDescriptorPR changes
- boing, that's it... no more
some dumps:
Before writing the fetch register:
CryptoChannelConfigRegister (f0042008), 0x00000000 0x0000071c
CryptoChannelPointerStatusRegister (f0042010), 0x00000000 0x00000007
CryptoChannelCurrentDescriptorPointerRegister (f0042040), 0x00000000 0x00000000
CryptoChannelFetchDescriptorRegister (f0042048), 0x00000000 0x00000000
CryptoChannelDescriptorBufferRegister 0 (f0042080), 0x00000000
after writing to fetch register
CryptoChannelConfigRegister (f0042008), 0x00000000 0x0000071c
CryptoChannelPointerStatusRegister (f0042010), 0x00000002 0x00000007
CryptoChannelCurrentDescriptorPointerRegister (f0042040), 0x00000000 0x002e9a98
CryptoChannelFetchDescriptorRegister (f0042048), 0x00000000 0x00000000
CryptoChannelDescriptorBufferRegister 0 (f0042080), 0x00000000
CCPSR changes to 2 (error), but i don't know why?
Nothing else (at least nothing i can see) happens.
