System Memory Map and Block Diagram Configuration for PNX17xx Series in Standalone Mode
3.2 The Specifics of the Boot From Flash Memory Devices
8-256 MB DRAM
In standalone mode PNX17xx Series fetches its TM5250 binary program and data
from a Flash memory device. The PCI module has internal DMA logic that allows,
with few MMIO register writes, to autonomously fetch data from Flash memory
devices (connected to the PCI-XIO bus) to the main memory. The typical simplified
board system is sketched in
same
(resistor pull-up or -down) on the BOOT_MODE[6:4] pins. The Flash memory device
used for boot must be connected and therefore selectable by the XIO_SEL0 pin.
In order to be able to access the content of the Flash memory devices the following
actions are taken in the boot scripts:
1. The XIO_ACK and the XIO_D[15:8] are removed from their reset state that sets
