Source Code for Driver and Application for DMA Read/Write using PCIE Avalon-MM Design

[Altera_Forum]

Hi, 

 Iam working on PCIE Avalon-MM Design using Arria 10 FPGA. Iam using the example design from the below doc to perform the DMA transfer. https://www.altera.com/en_us/pdfs/literature/ug/archives/ug-01145_avmm_dma-1.1.pdf   Iam testing this example design in Hardware using the application “altera_pcie_gui.exe” and the windows 64-bit driver for DMA Read/Write from the below link: http://alterawiki.com/wiki/reference_design:_gen3x8_avmm_dma_-_arria_10   This application run read DMA (move data from system memory to the on-chip memory in the FPGA), write DMA (move data from on-chip memory to system memory), or simultaneous read and write.    is it possible to get the source code of this driver (altera_pcie_win_driver) and the application as we need to modify this driver to build our own application to perform similar DMA Read/Write.   Please let me know where can I find the source code for this driver software.   Thanks.

Hi, 

 I'm also working on the same and need Linux driver code, application code for doing dma transfer between system memory and on-chip memory  Thanks,

Hi, 

 Altera does not provide the Windows source code for the PCIe driver. The reference design and Linux source can be found from related links in the AN690: https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an690.pdf  There is an example simple version source code from the following link that perhaps could be use as reference: http://www.alterawiki.com/wiki/pci_express_in_qsys_example_designs  Please be aware, the material from the wiki page can be publish by anyone and it is provided as-is and is not supported by Altera.  Regards, nyusof (This message was posted on behalf of Intel Corporation)
