PCIe x8 Gen2 for Stratix IV (usng QSys)

Honored Contributor II

People who have done designs in QSys for Stratix IV would have seen that QSys doesnt support x8 Gen2. It only supports either x8 Gen1 or x4 Gen2. I have my design running currently at x4 gen2, but I would like to get it running at x8 Gen2. If I dont use QSys I might be able to get it to running, but there are certain components I need to either add manually or do myself (avalon mm bridge and all the CRA registers etc.). I am not sure which is the easiest way to do it. has anyone done this? Thanks!

Hi eldos, 


We have developed a PCIe SGDMA solution supporting any PCIe configuration with support for Qsys. We offer drivers for Linux, Windows, QNX, Apple, etc  

For more information see our website; www<dot>lancero<dot>eu<dot>com

Thanks Marco, We are currently using Jungo drivers with QSys provided interface (Gen2 x4) with our own DMAs. I checked your website. For me, at this stage of development, it may not be an option to get service from an external company. I will have to do this myself. But I will keep in mind about this if something comes up in future.
