Changing ARM clock

Hi, I need to change the ARM clock speed (currently at 283Mhz) to a lower speed (168Mhz) to match what we're planning to use on our custom board. I know the change is somewhere in u-boot; does anyone one know what file in u-boot I need to modify? Also, unlike the kernel, I can't seem to

Re: Changing ARM clock

Never mind, I figured it out by looking through the Makefile; to build: 1) cd u-boot 2) make davinci_config 3) make all The file to change the ARM clock is in u-boot/board/davinci/platform.S Regards, Andy - Original Message From: Andy Ngo [EMAIL PROTECTED] To: davinci-linux

Small footprint filesystem

Hi, The DVEVM board comes with a HUGE filesystem on the 2.5” hard drive. On boot up, the Linux kernel mounts the partition (/dev/hda1) to be used as the root filesystem. The filesystem is 1.9GB! This is good for development purposes but when we have our custom board, we will only have a

Can the ARM and DSP accessing the RAM simulatenously?

I have question that I wanted to ask. The DVEVM board has 256 MB DDR RAM available to the ARM and DSP; according to the document that comes with codec examples, this RAM is partitioned as follows: · 0x8000 .. 0x8780 (0-120MB; size 120MB): Linux, booted with MEM=120M ·

Size of byte on DSP

What is the size of a byte or char on the DSP side? Is it 1 or is it 2 (data aligned at even boundary)? Thanks, Andy ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com

Merging enc and dec codecs

I'm trying to implement the open-source Speex codec (www.speex.org) into a Code Engine Server. The Speex library has both the encoding and decoding support functions. Does that mean I have to link the library to the CE enc codec and also to the CE dec codec? I want to save memory resources

Sound driver full duplex problem?

Hi, I'm trying to do an audio loopback by reading a sample from /dev/dsp and writing it back to /dev/dsp in a while loop; it will work for about 1 to 2 minutes and then no more audio (stalls on the read). I've seen other posts where the solution is to increase intermediate buffer but it
