Failed to open codec engine

The most common error in this area is using software components from different releases together.  This is very easy to do when you consider the different locations where the softwae components may reside; for example, a user can be working on an NFS mounted file-system and then switches to HDD without realizing it has not been updated to the same software release version as other components.  I have ran the demos in the latest release (1.30.00.41) and can confirm they work.  Have you finish going thru GSG.

I have already had a DM355 EVM and when I switched to DM6446EVM I also add below files to my DVSDK(1_30_00_41) and I follow the instructions in GSG.

dsp_bios_setuplinux_5_31_08_15.bin

TI-C6x-CGTEVAL-v6.0.15.1.bin

I did all in GSG except "4.8 Testing the Build Environment".

Can you tell me which files do I need just for the decode example for example? (What I have are: loadmodules.sh, cmemk.ko, dsplinkk.ko, decode, and the video data)

Do I need to add a codec to the same directory?

Section 4.5 and 4.6 of GSG are key since both these sections can be configured for DM355 or DM6446 and must be configured for the correct platform for things to work correctly.  Completing section 4.6 of the GSG should have copied the necessary DM6446 files over to the file system. 

I would double check section 4.5 and 4.6 in GSG first; if this does not work, please attach a full log starting from the boot process all the way to the error you get when you run the demo.

1)When I came to my office today and started the DVEVM6446 and run ./decode  it can start without a problem.  I did not change anything in my file system. Also ./dvevmdemo can work without any problem. But ./decode gave this error once and I had to restart the system :

root@192.168.184.70:/opt/dvsdk/dm6446# DSP-side configuration mismatch/failure
0              -> success
Positive value -> DSP-side failure code.
(Uint32) -1    -> DSP-side component was not initialized.

    DRV configuration status    [0x0]
    IPS configuration status    [0x1]
    POOL configuration status   [0xffffffff]
    MPCS configuration status   [0xffffffff]
    MPLIST configuration status [0xffffffff]
    MQT configuration status    [0xffffffff]
    RINGIO configuration status [0xffffffff]

2)In addition to that I could not run ./encodedecode which gives the error:

Encodedecode demo started.
TraceUtil> Error: Failed to open codec engine "encodedecode"
TraceUtil> Error: Aborting TraceUtil_start
Encodedecode Error: Failed to open codec engine encodedecode
Encodedecode Error: Failed to open codec engine encodedecode

How can I solve this problem ?

3)Here is my working but unstable boot proccess

Looks like the u-boot version you are using (1.1.3) does not correspond to the u-boot version included with this software release (1.2.0); upgrading may fix the problem.
