This prompt is also displayed as an indication that the monitor has finished executing a
command or function invoked at the command prompt (except when the command loads and
jumps to a user application). The hardware product name (ATCA-9305), and current software
version number are displayed in the prompt.
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 (see
Table 9-1 ). See Figure 2-7 for the
debug LED locations. In the event of a specific initialization error, the LED pattern will be
displayed and the board initialization will halt.
9.3 Basic Operation
The monitor performs various configuration tasks upon power-up or reset. This section
describes the monitor operation during initialization of the ATCA-9305 board. The flowchart
(see
Figure 9-2 ) illustrates the power-up and global reset sequence (bold text indicates
environment variables).
