1.9. Additional Chaining DMA Commands
|Run endpoint DMA||Write only Read only Read then write Write then read Read and write||Writes transfers data from the FPGA to system memory. Reads transfer data from system memory to the FPGA.|
|Scan the endpoint configuration space registers||Type 0 Configuration PCI Express capability MSI capability Power management capability||Reports the byte address offset, value and a description of the selected register set.|
|Scan the current PCI Express board settings||N/A||Reports the configuration settings for the development board.|
|Scan the motherboard PCI bus||N/A||Reports the vendor ID, device ID, slot, bus, and function numbers for all devices on the motherboard’s PCI bus.|
|Run target read||At endpoint address From 0x0 to endpoint address||Programs the Root Port of the motherboard’s PCI Express chipset to read from the FPGA’s memory, as follows:
|Run target write||At endpoint address From 0x0 to endpoint address||Programs the Root Port of the motherboard’s PCI Express chipset to write to the FPGA’s memory, as follows:
