BASIC OPERATION

The PmPPC7448 monitor performs various configuration tasks upon power-up or reset. This section describes the monitor operation during initialization of the PmPPC7448 board. The flowchart (see Fig. 11-2) illustrates the power-up and global reset sequence (bold text indicates environment variables).

Power-up/Reset Sequence

The PmPPC7448 monitor follows the boot sequence in Fig. 11-2before auto-booting the operating system or application software. At power-up or board reset, the monitor per- forms hardware initialization, diagnostic routines, autoboot procedures, free memory ini- tialization, and if necessary, invokes the command-line. Note that the U-Boot monitor has the ability to timeout while waiting for EREADY. See Table 11-2for default configuration set- tings.

Prior to the console port being available, the monitor will display a four-bit hexadecimal value on LED1 through LED4 to indicate the power-up status. In the event of a specific ini- tialization error, the LED pattern will be displayed and the board initialization will halt. Refer to Fig. 11-2for the LED pattern at the various initialization steps.
