PPC-E7 RELEASE 6-7-2010

Added code for new slower 65nm P30 flash.  
Added progress indicator for flash initialization. 
Fixed Cirrus debugtimer bug which caused problems with Sleep() and similar functions. (This bug only showed up in Sleep() or delayed rescheduling functions after a board has been running for over 12.5 days of continuous runtime).


PPC-E7 RELEASE 6-8-2009

Designed for use with 64MB FLASH/64MB RAM.  This is for use with PPC-E7 with the older P30 flashes.  This image should not be used with the newer slower P30 flashes.

The following updates are included:

	Improved NOR flash driver.
	TEXFAT filesystem for NORflash and USB drives.
	Provision for application launching on power-on or reset.
	Backlight is now controlled by the Display control panel.
	The wallpaper can be easily customized.
	Clear desktop
	
SDMMC is not supported in this revision.


APPLICATION LAUNCHING

During bootup CE looks for applications in the Norflash\Startup folder and runs each one of them.

If no files are found, it looks for the USB drive folder "Hard Disk\Startup" and runs any apps found in it.  If it sees no USB drive it will retry up to 30 times (about once per second) before going to the Windows CE desktop.  If It detects a USB Drive but does not find the startup folder, it will go to the Windows CE desktop immediately without retrying again.

If a jumper is installed connecting pins 41 and 43 on HDR1, the PPC will boot directly to the Windows
desktop without launching any apps.


BACKLIGHT CONTROL

The OS now controls the inactivity timeout for the backlight via the Display|Backlight control panel.  The battery power parameter is not used; The AC power parameter is the only one that is functional.  Any change to this registry parameter is immediately flushed to the flash based registry.

Following are some useful registry values for controlling the backlight.  Note that ACTimeout is automatically changed and flushed to persistent registry any time you change the "external power idle time" from the Display-Backlight control panel.

; Backlight tab of Display control panel (timeouts in seconds)
[HKEY_CURRENT_USER\ControlPanel\BackLight]
	"BatteryTimeout"=dword:0  ; not supported
	"ACTimeout"=dword:384     ; 900 secs or 15 min
	"OnBright"=dword:0100    ; "On" brightness.  0100 is fully on.
	"OffBright"=dword:0020    ; "Off" brightness. 0000 is fully off


WALLPAPER

The wallpaper is easily customizable by naming a jpeg file "wallpaper.jpg" and placing it in the folder "NORflash\Config".
