Because i thought adding configs for features not used by all boards not to
be a clean way of implementing it. I am confused as to why adding the
configs for the board that uses those features is being frowned upon, but
enabling them for boards which do not use it is fine. Can someone please
elucidate.
But if adding them to the defconfig file is ok, i will respin the patch
accordingly and resubmit. Thanks.

Don't even waste your time, it won't be acceptable.

Why? If the board doesn't have a NAND flash, it doesn't register the
platform device and the driver doesn't see it. What's the issue?

Note that a NAND flash is a default component of DA850 EVM board too,
nevertheless the NAND driver is not enabled in the defconfig.

Nevermind, the misleading comment made me think that NAND is mounted on the
EVM itself -- actually it's on UI daughter board, just like with DA830 EVM...

You're not just adding the MTD configs, you're *forcing* them, devoiding the
users of any freedom of choice.

Subject: Error While Running Demos
Message-ID:
<[email protected]>
Content-Type: text/plain; charset="iso-8859-1"
I'm trying to run demos for encode decode which came with DVSDK v1.30.01 for
DM6446 EVM
When i boot the board then I'm not seeing any demos which should run
automatically as per the TI doc.
So i opted to run the demos using command line.
First i loaded all the modules which are required to run the demos
Modules loaded :: cmemk.ko and dsplinkk.ko
[email protected]:/opt/demos/dm6446/decode/release# lsmod
Module Size Used by
cmemk 17368 0
dsplinkk 96360 0
But when i excute command to run the demo ::: ./decode -v
/opt/demos/dm6446/data/videos/davincieffect_ntsc.m2v -k
i get following error::
Decode demo started.
TraceUtil> Error: Failed to open codec engine "decode"
TraceUtil> Error: Aborting TraceUtil_start
Decode Error: Failed to open codec engine decode
Decode Error: Failed to open codec engine decode
[email protected]:/opt/demos/dm6446/decode/release#
Please help me out on how to make the sample demos run.
Thanks in advance.!
