1.5.2. fpga-configure

Use the fpga-configure utility to perform partial reconfiguration. The script accepts a .rbf file for a given persona. The script performs the following functions:
  • Communicates with the driver to remove device sub-drivers, if any
  • Communicates with the fpga-region-controller script to assert/de-assert freeze
  • Writes the .rbf to the Partial Reconfiguration Controller IP core
  • Re-deploys the sub-drivers, if any, that are required upon successful PR
To perform PR over PCIe* , run the following command: 
fpga-configure -p <path-to-rbf> <region_controller_addr>
Table 7.   fpga-configure Command-Line Options
Option Description
-p

Performs partial reconfiguration over PCIe* programming.

-d

Disables the advanced error reporting on the PCIe* link. Advanced error reporting generally reports any critical errors along the PCIe* link, directly to the kernel. If the PCIe* link is completely disabled, the kernel responds by crashing the system. You must disable advanced error reporting during full chip configuration, as full chip configuration brings down the PCIe* link.

-e

Enables the advanced error reporting for the PCIe* link. Use this option after full chip configuration to ensure the integrity of the PCIe* link.

-r

Prints the contents of a debug ROM within the reference design. Use for debug purposes.
