Latest Rockbox not working on Nano

Llorean:
My point was that you're making a faulty relationship.

If you leave an iPod Nano sitting in Room Temperature, you're not actively adding energy to the backplate. The only thing affecting the temperature change is sitting in the room.

If you're running current through a microprocessor, it heats up. Fairly quickly. Turn on your PC from a cold start, run your CPU at 100%, and see how long it takes to heat up. The backplate is not having current run through it, so even if the microprocessor heats up, it still may be quite some time before you feel the back plate at the same temperature.

My point is that you should use some scientific method in your experimentation rather than making assumptions. Correlation does not imply causation.

Why not use a thermometer to actually measure component heat in your Nano? If it goes from "Room temperature" to "Too hot" almost immediately, then a great deal of heat is added.

Another important fact: FLAC has LESS boost ratio than MP3. This means that FLAC runs the core processor cooler than MP3, and yet for many people FLAC is more problematic, not less as your theory requires it must be.

Please, look at all of the evidence, and perform structured testing, rather than trying to make leaps. While it clearly runs better for some people cooler, this doesn't mean that we're generating significantly more heat, it only means that "certain hardware performs better cooler", not strictly "we're making it too hot".

For example, in a hypothetical example, if something can be updated 60 times per second "cold" and 50 time per second "hot", and your code previously updated at 45, and moves to 55, it doesn't need to be operating at a new temperature to experience problems if it was always "hot" before, but if you cool it these problems will vanish despite a lack of change of original operating temperature. Which means that the problem is in how fast we update it (in this hypothetical situation) but a lept to conclusion could be that we make it too hot, since cooling seems to fix it.

So please, PLEASE, investigate thoroughly from every angle, rather than making any assumption. Even if it's right, PROVE that it's right, rather than simply assuming it is, by figuring out what's actually going wrong. Even if it's overheating, we need to know WHY it is.

aressto:
when trying to play mp3 file, ipod nano 2gb says:

Undefined instruction at 40003934 (0)

and freezes

using

iPod Nano 1st gen
r14976


tryed different releases for a 3-4 days, same thing

Would you please recomend stable release and where to download it

aressto:
i tryed one by one rockbox-ipodnano-20070904.zip
rockbox-ipodnano-20070905.zip
rockbox-ipodnano-20070921.zip

GodEater:
Please don't double post.

tvg:
Llorean, you are right.
Next days I'll manage an "experiment" with clock timer. Unfortunately, I can't disassebmle it.
