Re: A2DP works, help me test it?

1. take the old tarball from lardman: http://people.bath.ac.uk/enpsgp/nokia770/dsp/sbc/ARM-only/bluez-utils_3.28-0osso6.tar.gz

Re: A2DP works, help me test it?

No, but that should be simple: http://talk.maemo.org/showpost.php?p=268526&postcount=307

Just the content of 'sbc' subdirectory from bluez-4.67 should be used now.

Re: Why does Nokia give us such a low default 600MHz?

OTOH the timing is a bit suspicious :) TI announced 720MHz version at about the same time when the mass production of N900 and the other omap3 based phones started. It could be an indication that the...

Re: Why does Nokia give us such a low default 600MHz?

They were not overclocked for sure. Those chips are "speed sorted OMAP2" and are really rated by TI as being able to run at 400MHz clock frequency. Have a look here:...

Re: Overclock the N900?

It seems to be more complex than this. Based on the tables from the datasheet, the lifespan gets significantly shorter if CPU runs more than 1/4 of time at 600MHz. I guess in reality there are no...

Re: Overclock the N900?

That's not quite right, the device is actually in off mode most of the time (and not clocked at all), so it is neither running at 125MHz nor 250MHz. The lowest operating point helps to reduce battery...

Re: Overclock the N900?

It's 5 years only if you never clock it higher that 600MHz (or 720MHz for the latest omap3530 revisions). If each extra 100MHz decrease lifespan twice, you can do the math about how long it will last...

Re: Overclock the N900?

There is an official datasheet from TI (for omap3530 which is very similar to omap3430) with the information about the expected lifespan. Running the chip all the time at 600MHz vs. 500MHz already...

Re: Ufo2000

Not yet. Moreover, the upstream project has slowed down almost to the standstill soon after I stopped actively looking after it :( But thanks for bumping the thread.

Re: Using PC to delete the wrong partition will fix the problem if stepped into this

Just don't use sfdisk, it is buggy and can fail like this. Unless somebody gets really annoyed and fixes it, fdisk is a much better alternative :)

You could also just clear the flash card...

Re: N810 media player, very strage issue

You can try to reflash kernel only. Take the latest official firmware and unpack it:
flasher -u -F RX-44_DIABLO_5.2008.43-7_PR_COMBINED_MR0_ARM.bin
You will get lots of files extracted. File zImage...

Re: Video can be better than expected !

Re: Fbreader hard resets N800

It's a good idea to check memory cards for filesystem corruption. It the filesystem is corrupted, swap file used on it may behave unstable.

Re: Who finds themselves coming to these forums less after the change of image?

Re: Best video quality supported by N800 and N810 via mpalyer

Yes, audio pipeline is a major pain on N8x0 devices. It goes through ESD daemon and ends up in DSP. It is hard to even get audio/video playback in sync, let alone be sure that no extra cpu resources...

Re: Best video quality supported by N800 and N810 via mpalyer

That's a vague statement. Of course any software is limited by hardware capabilities. But reaching the real hardware bounds is possible only with really well optimized software. And mplayer/ffmpeg is...

You probably need a gstreamer plugin for mp3, which works both as sink and source.

Also sbc gstreamer plugin is very slow and has huge cpu overhead. I have not measured its performance on ARM11...
