PCI-E DMA Failure

Question

Hi folks,

I run into a problem using Altera OpenCL and the Nallatech PCI-E 385N under Windoze. Everything works as intended and data is valid when using the AMD OpenCL SDK under Linux with the exact same code.

Has anyone ever got this error while writing a buffer? Got a clue for me?

MMD FATAL: acl_pcie_dma_windows.cpp: WDC_DMASGBufLock function failed.

Thanks in advance!

Edit: BTW, does someone know when the 14.1 software is going to be released? It was happening in November in the past...

I still get this error in 14.1.

Hi The Smith,

Nallatech has a new version of the Windows PCIe driver which will be released as part fo the next version of the BSP (R001.003.0001).

You can always contact Nallatech Support for early access (http://www.nallatech.com/support/support-inquiry)

Thanks
