Alright. If the charging bug is already known then I guess it'll be fixed in due time then (I will likely update to the latest SVN again once that has been fixed).


Now as for the LCD type in the hardware info, I see this:
LCD Type: 1

This should properly shut down all iPod Photo and iPod Colour LCDs:
http://drop.io/dreamlayers/asset/rockbox-20348-ipodcolorphoto-lcd-shutdown-zip
Please report "LCD Type:" from the debug menu again.  With that build, it can also be 3.

Technical info: 
It seems the Color iPod can have 4 different LCDs.  They're detected via two GPIO bits in lcd-color_nano.c.  0 and 2 are the old LCD with an unknown controller and they use the same init, shutdown and update procedures.  1 and 3 are simillar to HD66789R.  They have different init and shutdown procedures but they share the same update procedure.   Before, both were being reported as type 1. 

I could further develop this code into the HAVE_LCD_SLEEP feature.

I actually rolled back the firmware to the latest stable version again (due to the recharging bug which will cause complications once the battery runs dry and I can't turn on the ipod any longer. I'll feel much more comfortable using the latest SVN once that is fixed). Therefore, 3.1 was the version running when I reported the LCD type which was "1". Would it report differently in the most recent build in other words you would need me to re-install the latest firmware again and retrieve the LCD type from that? Also, is the version you uploaded contain a special fix for the LCD issue?

Yes, the version I uploaded should properly shut down the LCD and fix the problem.  It is a .zip file which may be installed in the usual way.  If it fixes the problem, I will submit a patch.

All official builds report "LCD Type:" as 0 or 1.  The version I uploaded should report 0, 1 or 3.  I was asking you to check the type again with this custom build to see if it is 1 or 3.  It's useful to know which type has this problem, and if the problem is fixed, that the fix has been tested for that type.

Yup  :) That version you uploaded DID fix the problem but if you still need the information:
Hardware rev: 0x00060004
LCD Type: 3

Also, did you by any chance happen to overcome the charging issue in that version as well or should I roll it back again (I don't want my battery to run dry with no means of recharging it although I could simply load the apple firmware manually in order to recharge).

No, I did not include a fix for the charging issue.
