Powering Up the System

The following table shows what takes place when you turn equipment power ON (depending on whether 187Bug is in Board Mode or in System Mode):

If 187Bug is in...

Board Mode	187Bug executes some self-checks and displays the debugger prompt
	187-Bug>

System Mode	The system performs a	If the conÞdence test fails, the test aborts

		control then returns to the menu (refer to
		Chapter 4, Debugger General
		Information, and Chapter 5, Using the
		187Bug Debugger for ENV and MENU
		commands).

Initializing the Real-Time Clock

The onboard real-time clock (RTC) is backed up with a self- contained battery. Before shipment of this board, the clock of the RTC device was stopped to preserve battery life.

The boardÕs ÒSelftestsÓ (ST) and operating systems require the clock of the RTC to be operating. Table 3-15shows the steps required to initialize the RTC, depending on the mode.

Examining and/or Changing Environmental Parameters

Use the 187BugÕs ENV command to verify the NVRAM (BBRAM) parameters, and optionally use ENV to make changes to the Environmental parameters. Refer to Appendix A for the Environment parameters.
