DSP CPU load is always 99%,and then the system will be halted

Hi， Everyone。I have some problems about my platform of davinci dm6446, which is developed by my professor's group. The problem is: When I run the encodedecode demo on my platform, after a few seconds, the DSP CPU load is 99%，and then the system will halt for ever. Can anyone tell me the possible p

[PATCH 1/1] ARM: DaVinci: Don't read from write only registers

about AIO support

Does anybody know if AIO can be bypassed in the Gadget FS application if I do not want to do any IO operation on my ISOC endpoint in user space? I will try to set up DMA instead to let DMA take care of ISOC streaming in kernel? Which means I do not need to handle ISOC endpoint in user space. Can

Re: about the ths8200 register set

The margins and sync_len don't seem right. I don't have my settings with me so I can't check . Look at this website. It will help you find the settings for the margin and sync pulses. http://www.tkk.fi/Misc/Electronics/faq/vga2rgb/calc.html - Brad On Nov 26, 2008, at 11:47 PM, Lori Gao wrot

Hi, Where are you hard-coding buffer size? Can you also check whether user pointer buffer exchange mechanism is supported in the driver? Thanks, Brijesh Jadav From: Mr. V R [mailto:[EMAIL PROTECTED] Sent: Friday, November 28, 2008 6:18 PM To: Jadav, Brijesh R; d

I am not getting any error after hardcoding buffer size to 884736, and able to dequeue and enque buffer successfully, but this buffer does not contain any frame data. On Fri, Nov 28, 2008 at 5:10 PM, Jadav, Brijesh R <[EMAIL PROTECTED]> wrote: > Hi, > > As far as I remember, earlier dm644x captur

RE: Requesting for help:

Looks like the Monta Vista toolchain is used. Alternatively, you can try adding /opt/montavista/pro/bin in your search path. There should be a pre-compile mkimage binary there. Regards, Steve On Fri, 2008-11-28 at 17:40 +0530, Jadav, Brijesh R wrote: > Hi, > > > > I think you need to comp

Re: Need help with V4L2 USERPTR method

Hi Andrea, Thanks for reply. 1) DVSDK 1.30 kernel does not provide CONFIG_CAPTURE_DAVINCIHD ( I could not find in autoconfig.h or KConfig anywhere, but Makefile mentions about it). Do I have to apply patch to enable support this? (I tried tweak it manually but looks like I have to disable part of

Hi, As far as I remember, earlier dm644x capture code was not supporting user pointer buffer exchange mechanism. Can you tell me which error you are getting? Does it allow to do reqbuf? Thanks, Brijesh Jadav -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf
