: Good reading info - thanks! I had similar problems (bit of an audiophile meself) but I've used the BioEq libraries: http://www.head-fi.org/wiki/bioeq-rockbox and they work great both with my sennheiser headphones as well as my philips dock. The sound has a natural fullness now, which is improved once you adjust the freq response to the natural response of the speakers.

::: Hi Vasyl - try the thrum or throb settings with any decent headgear and you'll see the difference. You may have to modify the freq response a bit to match the dynamic response of your own headphones, but it's way better than the default settings. With regards to r755, you need to build, modify and compile the code yourself off the svn, and you'd most likely need to have some flavour of linux installed as your primary (or virtual) os. If you're not familiar with basic code development it would probably be best to wait until /7 or someone else releases a more updated EmCORE version, ideally with some better lcd and ide handling (my drive groans awfully when seeking long tracks, unlike apple's firmware). But r755 (and r708) are way better than the original apple software!

== Classic and RGB666 capabilities ==
 +
 +
Hi TheSeven/User890104
 +
 +
I know this is not about an 'official' EmCORE release, but I need to flag it up to the development team just in case. As of r746 my ipod6g (classic) w/ emcore does not initialise rockbox correctly. EmCORE loads up perfectly, but when Rockbox is selected a few garbled pixels are displayed at the top left hand corner and the LCD is never properly initialised. Rockbox is still fully functional though (play/seek/usb/etc) but the display doesn't work.
 +
 +
I seem to have tracked the culprit down to a change in the RGB666 driver in r746&r747, and having reverted the changes from the SVN, I can successfully build any version which works well, up to the most recent build (r764). The latest 'vanilla' svn version r764 still doesn't work properly on my ipod6g, so I wanted to flag this up just in case you may be using some slightly different hardware to test any 6g functionality.
 +
 +
On another note - great work so far - I'm really impressed with the work & functionality to date - can't wait for some new snazzy features such as piezo, better pm and proper undervolting again!
 +
 +
Hope this helps!

Voltage reduction on classic

Reducing the CPU core voltage on the iPod Classic has been disabled. Battery life might be adversely affected.

Is it good or bad? (:

In general, this is bad (and should eventually be handled differently) as the CPU now consumes more power than actually necesarry, but for now, it solves problems where it didn't work properly due to a too low voltage. --Benedikt93 13:03, 2 May 2011 (UTC)

Classic and RGB666 capabilities

Hi TheSeven/User890104

I know this is not about an 'official' EmCORE release, but I need to flag it up to the development team just in case. As of r746 my ipod6g (classic) w/ emcore does not initialise rockbox correctly. EmCORE loads up perfectly, but when Rockbox is selected a few garbled pixels are displayed at the top left hand corner and the LCD is never properly initialised. Rockbox is still fully functional though (play/seek/usb/etc) but the display doesn't work.

I seem to have tracked the culprit down to a change in the RGB666 driver in r746&r747, and having reverted the changes from the SVN, I can successfully build any version which works well, up to the most recent build (r764).
