Texas Instruments XIO3130 EVM manual

1.1 Overview SLLU108 – July 2008 XIO3130 EVM The Texas Instruments XIO3130 EVM is a functional implementation of a four-port PCIe-to-PCIe switch. The XIO3130 EVM was designed to allow validation of three separate functional modes. In normal mode, the EVM is configured as a generic PCI Express (PCIe) switch. In hot-plug mode, downstream ports 1 an[...]

1.2 Normal-Mode Operation Normal-Mode Operation www.ti.com By default, the EVM should be configured to operate in normal mode. The six jumpers (J7, J11, J13, J14, J15, and J16) should be covering both pins of each header (see Figure 1-2 ). Figure 1-2. Power Jumpers The dipswitch should be configured with SCL slide switch in the up position and DN1_[...]

1.3 Hot-Plug-Mode Operation www.ti.com Hot-Plug-Mode Operation Figure 1-4. GPIO Control Register • General control register (PCI register offset: D4h in each downstream bridge) – RCVR_PRSNT_EN = 0b – PRSNT pin is used to determine whether slot is present – REFCK_DIS = 0b – REFCK enabled – LINK_ACT_RPT_CAP = 1b – Slot is link active re[...]

Hot-Plug-Mode Operation www.ti.com Figure 1-6. Dipswitch Configuration The EEPROM (U3) should be reconfigured for hot-plug-mode operation. See Section 1.5 for an explanation of how to configure the EEPROM. Upon deassertion of PERST, the XIO3130 automatically reads data from the EEPROM. This data is used to preset various PCI configuration register [...]

1.4 ExpressCard-Mode operation www.ti.com ExpressCard-Mode operation • General control register (PCI register offset: D4h in port 1 and port 2 downstream bridges) – RCVR_PRSNT_EN = 0b – PRSNT pin is used to determine whether slot is present – REFCK_DIS = 0b – REFCK enabled – LINK_ACT_RPT_CAP = 1b – Slot is link active reporting capabl[...]

ExpressCard-Mode operation www.ti.com Figure 1-8. ExpressCard Adapter Board To configure the XIO3130 EVM for ExpressCard-mode operation, connect the ribbon cable connector from J1 on the adapter board to one of the matching connectors (J2, J3 or J4) on the XIO3130 EVM board. Then plug the adapter board into the adjacent PCIe slot as shown in Figure[...]

www.ti.com ExpressCard-Mode operation Figure 1-9. EVM Configuration for ExpressCard Mode To configure the XIO3130 EVM for ExpressCard-mode operation, the six jumpers (J7, J11, J13, J14, J15, J16) must be populated (see Figure 1-5 ). This routes power directly to slots 1 and 2 bypassing the TPS2363, which is not required for ExpressCard operation. T[...]

1.5 Using WinROM to Configure the EEPROM Using WinROM to Configure the EEPROM www.ti.com The EEPROM (U3) will need to be reconfigured for ExpressCard-mode operation. See Section 1.5 for an explanation of how to configure the EEPROM. Upon deassertion of PERST the XIO3130 will automatically read data from the EEPROM. This data is used to pre-set vari[...]

www.ti.com Using WinROM to Configure the EEPROM Figure 1-11. EEPROM Data To update the entire EEPROM from a .dat file that was provided by TI, right click on the XIO3130 entry (see Figure 1-12 ). Select the option "Program EEPROM Data From File." Figure 1-12. Updating the EEPROM SLLU108 – July 2008 XIO3130 EVM 9 Submit Documentation Fee[...]

Using WinROM to Configure the EEPROM www.ti.com A new dialog box appears that allows the user to select which .dat file to use to program the EEPROM (see Figure 1-13 ). Select from one of the three operating modes supplied with the EVM. Figure 1-13. Selecting a .dat File After the Open button has been pressed, a new dialog box opens asking if the u[...]

1.6 Using the TopHAT Utility www.ti.com Using the TopHAT Utility Once flashing has completed, the contents of the EEPROM now contains the data from the .dat file. However, this data is not yet present in the PCI configuration space of the XIO3130. Once flashing has finished, WinROM displays a dialog box reminding the user to power cycle the system.[...]

www.ti.com Using the TopHAT Utility TopHAT parses the PCI configuration space looking for any capability structure. If it finds a capability structure, a new icon and description of the capability will show under the device. For example, under the XIO3130 PCI/PCI bridge (TI) entry, a capability for Power Management Capability Structure is shown wit[...]
