Hello ,
I am trying to build an application to encode video in mpeg4 format
and also integrate the scale example from the codec engine in the
encode combo server. During the integration fro performance reasons I
want to increase the L2 cache size from 64k to 128k. My processor is
tms320dm6446.
Hello,
I remember 64x+ L2 cache size is 64K (maximum).
Regards
Jayakrishnan

Title : Unable to change cache size in codec engine.
Hello ,

Refer to tms320dm6446.pdf /p14 (datasheet of TMS320DM6446) DSP has only
64KB
The DSP Subsystem includes the following features:
· C64x+ DSP CPU
· 32KB L1 Program (L1P)/Cache (up to 32KB)
· 80KB L1 Data (L1D)/Cache (up to 32KB)
· 64KB Unified Mapped RAM/Cache (L2)
· Little endian
Best regards
thanks

All,
Could anyone show me how to convert video clips with other encoder formats
to be playable by dm355 mpeg4 sp decoder using open source tool (ffmpeg or
others)? I need not ArcSoft MediaConverter(I need a free tool). Thanks very
much.

Hello,
Sorry for the confusion. I am able to boot using SPI and SD with the
MV-kernel and I am content with that. But I wanted to see what
linux-davinci had to offer.
For SPI, you would have to take Sandeep's DM355 SPI patches (posted

Thank you for the suggestion. Troy's patch works fine on DM355 EVM.

Troy,
I tried this patch on DM644x EVM and following are my observations:
1. Playback works fine.
2. Record has some issues. Recorded stream has Loud volume on
the right side, and on the left, volume is very low.
3. Loopback (arecord -f cd | aplay -f cd) has some issues.
Audio is bit noisy here.
Hi Kevin,
in general you are right, but in this case is the execution of the
bootloader to fail and there's no way to address the problem after reboot.
I think there's a problem in the logic implemented in the cfi flash driver:
some driver operations don't leave the chip in read array mode and
