Hello gladarmy,
I had the same problem, and I sent request to support.
Here is the answer:

DM644x devices, as the suggested development path is with the ARM running

Hi,
i have read the "DSP two-level internal memory reference guide (spru610)" &
"DSP cache user guide (spru656)" but
still have some questions about the dm6446 DSP side's cache:
1. by reading these two guides, it seems that level-1 memory ( L1D, L1P) are
always used as cache and level-2 can be co
Hi, all.
I download EVM packages from TI site. As you know,
evm packages provide many tools including
tievms/dvevm_/codec_servers_XXX/. The server contains
some dsp images like decodeCombo.x64P etc.
It is common to rebuild the decodeCombo.x64P server.
By checking TI document, I am told that co
Hi,
for enabling caches in run time have a look into
http://focus.ti.com/lit/ug/spru401j/spru401j.pdf
especially the CACHE section.
If you want access CMEM/DSPLINK data for example (that should be in DDR
0x87 - 0x88 ) you simply #include to your DSP code and write

Hi Steven,
from what I know from cmem_1_02, the device node is not created from the
kernel module itself.
You can try to run
mknod /dev/cmem c 254 0
yourself, or simply edit loadmodules.sh.
By the way, you can check what cmem is doing running
cat /proc/cmem

Hi, Tivy
I have a question.
Can you confirm that doing DSP reset is safe and does no harm to ARM side?
To be more specific,
1. could DSP reset corrupt DDR memory?
2. How about peripherals?
3. Or EDMA?
I am thinking another way.
The theory is, if the DSPLINK on DSP side can detect the link is gone
Please check your hardware design, especially your pcb layout:
1. Check whether your PCB layout follows IDE design rules;
2. use proper resistors.

Hi,
We figured this out, we had enabled the pinmux so we could use UART0,
however this kills the DMA!
Its just as well we no longer wish to use this serial port (never really
got it working) so we just set up the pinmux to exclude it.
Pretty annoying!

Hi,
I tried running my application using CE_DEBUG=2 environment variable. It
showed a debug message that its unable to locate the decoder. I am using the
same configuration file provided by TI in decode demo. I am attaching the
decode configuration file and the log file.so can u please let me know
... and by UART0 I meant UART1!

You're both looking at documents that do not apply to the DM6446.
Please go to the DM6446 product folder for documents applicable to this

Steven,
Did you use the provided Makefile (which includes ../../Rules.make)?
There is a macro USE_UDEV that needs to be set to 1 in order to get
insmod-time /dev/cmem creation. This setting of USE_UDEV is usually
done in the provided 'make' file Rules.make and is 'consumed' in the
rule to build c

Santosh,
the error implies that mpeg2dec is not part of decodeCombo.x64P. I would
go look for the decode.cfg used with the server and see if it is
included there. And make sure that mpeg2dec is actually built into the
server you have.

Thanks, Andre! You are right, I need to create device node myself though
its major number is 253.

Yes,USE_UDEV is disable.
If I enable it, compile error arises.
class_simple_create not define.
My kernel version is 2.6.23 which is cut from davinci tree.
As I know, udev is included in almost every 2.6 kernel based Linux
distribution.But why davinci kernel tree does not support it?
However, I ca
Hi, all.
I update cmem from 1_02 to 2_00_01, and insmod it correctly.
But while running demo application, I am out of luck.
cmemk reports GETPHYS failure.
my kernel mem params is 120M. I have no idea what can be the magic?
It seems get_phys() return zero.
Thanks.

but in my default BIOS .tcf file, it seems all the L2 are used as SRAM.
