Fix lag on Rockboy

[Goodyob]

I've been using Rockbox continuously ever since they perfected all Rockboy glitches in the 09-09-09 edition. When I finally got around to updating my Rockbox to the current build, I was shocked to find Rockboy running very slowly and the sound being all choppy even with good framerate. Everything worked fine in the 09-09-09 edition! What happened?

If it was because of the slowing down the processor, please add a button somewhere in the menu that provides an option for normal processor speed (for MicroSD), and for overclocked processor speed (for Rockboy).

I am running the Sansa Fuze edition.

Can you compile your own builds and figure out when it change?  This is pretty unlikely to be looked at if you don't figure out which commit broke it. 

[Goodyob]

I don't really know how...

Actually, I think the first "official" build for Sansa Fuze (the one that wasn't the unstable port) was the one that broke Rockboy, since MicroSD was the only issue with the Sansa Fuze port before they released the official version, and the way to fix MicroSD was to slow down the processor.

Like I said, they should add a button on the menu that lets you choose the processor speed, because some people never use MicroSD and for Rockboy to run good, the processor needs to be overclocked.

[saratoga]

You can already set the processor speed from the debug menu.

[torne]

Rockboy already boosts the processor while it's running.

[Goodyob]

I just got the latest simulator, and I couldn't find the option to change processor speed.

What I meant was to add a button that lets you overclock the processor so that it's fast enough for Rockboy...

[torne]

The simulator doesn't have a processor, which is why you can't find any such button.

And the button in question just controls whether the CPU is boosted or not, and rockboy already sets the CPU to be boosted, so it won't help you anyway.

If you want to actually clock your processor higher than the boosted frequency we use (which is, generally, the fastest speed on a given platform which is actually safe or stable, since it works best that way), then you would have to modify the code yourself (and it's unlikely to be trivial, either; you will likely have to mess around with the entire clock setup of the device).

[Goodyob]

So there's no possible way of having an overclock button without modding the whole thing? In that case, I think I'll just stick with the 09-09-09 edition...

[torne]

As Llorean said, if you can track down which specific change made it perform worse, then someone might look into it and fix the problem.

Just claiming you need to "overclock" the processor to get it to work better doesn't really help...

[Goodyob]

It was the first official release because they needed to slow the processor for MicroSD. I remember now because every time I checked the little chart for unstable releases, it always said that they had everything fixed except MicroSD, which supposedly corrupted because "we are currently running the processor's clocks way too fast". Right after they released the official edition, Rockboy started to be really slow, and the sound quality started being really bad.

If it helps, I still have the 09-09-09 edition's ZIP file (not the source code).

So it worked in August? 

[Goodyob]

(09... September maybe?)

Yes, the 09-09-09 edition had Rockboy perfected. So yes, it worked then.

hello, can i have the 09-09-09 version of ur rockbox? because rockboy on my ipod video 5g lags alot thanks

It lags on your ipod  because your ipod has a slower processor then the Fuze being discussed here.  The only thing you can do about that is try and optimize rockboy some more (no idea how much that would help though).
