7535 Hardware Reference Guide 33
Chapter 3: The Software
User Interface
When the main operating system is loaded and run, a splash screen is
displayed on the terminal’s screen.
At the end of the boot process, the 7535’s shell is displayed on the screen.
Status messages are written to the 7535’s serial console ports during the boot pro-
cess. The peripheral controller and the main processor console ports are multiplexed
on the same physical port. They use different command prompts to let the user know
which processor is displaying the status message.
The peripheral controller can display the following messages on the console port:
Starting BooSt
No image in the NAND flash
No/Invalid image on CF card
PXA250 jumping to BooSt
The main processor (the PXA250) can display the following messages on the
console port:
Starting BooSt
Recovering from sleep
PXA250 jumping to Windows CE
Going to BooSt prompt
Valid image in flash date code = <date code>
Invalid image in flash
Valid image on CF card date code = <date code>
Invalid image on CF card
The user has also been given the ability to adjust when certain transition times are
affected. This is done using the Power Properties applet in the Windows Control
Panel. One of two power schemes, ‘AC Power’ or ‘Battery Power’ can be chosen.
The following options can be changed by the user:
Switch To Suspend
This is the amount of time the unit is idle before the unit executes the Run-
to-Suspend transition. This setting is on the Schemes tab of the Power Prop-
erties dialog. Possible settings are: Never, 1, 2, 3, 4, 5, 10, and 30 minutes.
