6.6.4.1. R-Tile Information

The following table lists a summary of the R-Tile PCIe IP parameter settings in the PCIe IP Parameter Editor when the IP was generated, as read by the R-Tile Debug Toolkit when initialized. Depending on the Hard IP Mode selected during the IP configuration (for example Gen5 2x8), then this tab will populate the R-Tile information for each core (P0 core, P1 core, etc.). Also, please note that:
  • All the information in the R-Tile information tab is read-only.
  • Use the Refresh button to read the settings.
