Ipod nano 2nd gen - white screen

(1/6) > >>

siouxes:
Hi guys,

 i have an old ipod nano 2nd generation and some days ago i read about rockbox. I am not a linux noob and i use the rockboxutility to reborn my pod to a new life.
So, i read on port status that now ipod 2nd gen is supported, since rockbox 3.7.

RockBox utility says that installation was going all done, but after reset my ipod, after the apple logo, i can read "rockbox" on the screen for a while, and than all the LCD fade to a 100% white.

The strange things, is that if i connect my earpiece, and move the clickwheel, i hear rockbox TTS that says to me in wich menu item i am!!!

So, seems to be that rockbox is working, but somethings goes wrong on LCD initialization, i think.

Just for information, i tried all version under the 'release' folder, from 3.7 to last one 3.8.1. I have also tested the latest build version with the same behaviour.
Notice that between one version to the other, i always recover my ipod via itunes, so i am sure that firmware nor files on my pod was corrupted.

I am available to any test, i really want to have rockbox installed (and working) on my ipod.

BR to all.

Simone

I'm no ipod nano 2g expert, but a slow fade to white (like a blooming effect) of the LCD generally means that the display is no longer driven by the LCD controller.

It's a bit odd that you do see a rockbox logo at the start. Perhaps the logo was shown by the rockbox bootloader and the display driver is somehow not working in the main rockbox firmware.

Hi bertrik, from the wiki:

http://www.rockbox.org/wiki/IPodNano2GPort

in status section, says:

LCD driver    - Done - Full functionality implemented and reasonably optimized (since r28813)

I am using latest SVN source, r29749.

I think that my ipod, probably, has some hardware difference or other things that i don't know... the reason for this thread is that i googled this problem and i found other rockbox users with the same issue... so, i have some time to spent over this and i think that is good to use this time to help this project to enlarge the device compatibility.

(excuse for my english, i hope it's clear...)

Chronon:
Your English is perfectly clear.  :)

I agree that initial display of the Rockbox logo then a slow fade to white gives the appearance that the bootloader and firmware are doing something a bit differently.  Do different contrast values have any effect?
