About the cache issues of dm6446

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

How to rebuild codec server?

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 CACHE_enableCaching ( CACHE_

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 -- Andre Subject: cmem issu

Re: Unclean CODEC engine shutdown.

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. Regards Gao (www.ruiva.com.cn) 2008/6/11 Andrew Armstrong <[EMAIL PROTECTED]>: > I was wondering if any resolution to this problem was ever found? I

Re: Hard Disk DMA Problem

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! Regards, Andrew On Wed, 2008-06-11 at 18

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. Sam -Original Message- From: [EMAIL PROTECTED] [mail

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
