Audio stream goes silent in loopback

Hi all, I am working on Davinci customized board. It has aic23 audio codec which is configured as Master and McASP configured as slave. Kernel version is TI MVL LSP 1_20_00_05. My task is to capture and play audio stream (loopback) on the board. I am able to capture and play audio strea

RE:Upgrading NOR flash from 16MB to 32MB

Tnx, i have already changed u-boot/include/configs/davinci.h in u-boot to 0x200 but when I look into kernel for DAVINCI_CS0_PHYS + SZ_16 -1 I can not find it. I am using MontaVista's linux-2.6.10_mvl401. Any ideas? Regards, Benjamin Manjunatha AM <[EMAIL PROTECTED]> wrote: Hi, You need

RE: What is the relationship between Codec Engine and DSPLink

Yan Ming, Codec Engine is a codec execution framework that automates the invocation and instantiation of eXpressDSP-compliant codecs and algorithms. TI Codec Engine is provided as part of the TMS320DM644x Digital Video Evaluation Module (DVEVM). Codec engine can execute in ARM-only, ARM-DSP, or

RE: How and when DSP BIOS load and run,and what about .x64P?

RyanYee, I can answer your question from the perspective of DSP/BIOS Link. The loading of the DSP executable occurs when the GPP side application calls the API PROC_load. When the GPP side application calls the API PROC_start, the already loaded DSP/BIOS application starts up. This triggers th

Hi Ben. I guess this is my first posting ;-) Glad I can help you First, DVEVM already, Did, have a 32MB NOR Flash. Second, Even if you install the 32MB Flash. Youo will be able to use only 16MB due to the limit of address line on AEMIF. Regards, Ashuaria 2007/12/25, Zgembo Adislic <[EMAIL PROTE

Upgrading NOR flash from 16MB to 32MB

Hi all, I am using DVEVM 6446 and I have changed my existing NOR flash chip from 16MB to new one that has 32MB. What changes do I need to make so that my board can recognize this new 32 MB of NOR flash? I presume that I need to make some changes to u-boot. Tnx, Benjamin -

What is the relationship between Codec Engine and DSPLink

Hi, What's the relationship between between Codec Engine and DSPLink? Which one can be downloaded freely from TI's website, and which one must buy DVEM in order to get it? I am interested in development for DM355. Because no DSP in the DM355, do I still need DSPLink? Thanks & Regards, Y
