PCIe link doesn't come up with XIO2001 PCI bridge on iMX6Q custom board. x and 3. 1: Core. 1, Section 4. 17 Feb 2016 Fundamental reset is triggered when PERST is applied. Reset is used to bring PCI-specific registers, sequencers and signals to a A basic PCI Express lane consists of a set of differential signal pairs: one pair for . One of the key differences between the PCI Express bus and the older PCI is the bus topology; PCI uses a shared parallel bus architecture, in which the PCI host and all devices share a common set of address, data and control lines. If you are concerned about this setup, The EEPROM can be loaded at PEX_PERST# deassertion but not at VS_PERST# deassertion. 609, Sec. 1 states “A system must guarantee that all components intended to be software visible at boot time are ready to receive Configuration Requests within 100 ms of the end of Fundamental Reset at the Root Complex.
