Set CPU Frequency permanent at 70?

(1/3) > >>

Jon:
Hi, I got a 4g ipod. Rockbox is unstable, and locks/crashes the ipod. By reading some thread I found out that setting the cpu frequency to 70 in the debug menu would help, and it has. It does not crash any more.

Anyways.. the "problem" now is that the cpu frequency is reset every time the ipod reboots. Is there any way to set the frequency to 70 permanent?

Thanks!

Llorean:
Oddly enough, before we had CPU scaling support, it WAS set permanently at 70.

There's not a way to do it, because once it works properly, there will never be any reason to do so. Just have patience for the bugs to be fixed, or compile your own build with CPU scaling disabled.

Jon:
okay, thanks!

Keep up the good work! :)

how do i change the cpu frequency? i found it in the debug menu, but it won't let me change it. my ipod freezes up at least once every time i play all the way through an album.

michael.conner:
If you're compiling your own Rockbox, comment out the line that reads "#define HAVE_ADJUSTABLE_CPU_FREQ" by putting "// " in front of the "#" sign in the file "config_ipod4g.h".  Once you compile it, you'll have a custom build that has CPU scaling disabled.  

I did this and it worked just fine when I had a 4G iPod.  I ended up selling my 4G on ebay and getting a 5G, to be honest, which plays nicer w/Rockbox.
