please,please help me for endpoint plus IP core DMA of virtex5LX50T

Hello every one, (1)I try to simplify the debug, I use /MAXMEM switch in boot.ini to reserve 1G memory from windows OS to use it for DMA experiment (write from device). I want to know, my hardware(virtex 5)can operate this reserved memory in DMA way without any driver help in windows or not? Because I want to make sure all the hardware action is right at first step. So I don’t want to code a driver in windows for my card to minimize driver impact for the debug. (2) After I did first step described above. I found endpoint plus IP core report me trn_tdst_rdy_n signal and it looks like the internal TX buffer of IP core is used up, I also found nothing in computer memory reserved by /MAXMEM switch in boot.ini. this is caused by my first step or by some other reason? Thanks for the help.

Hi,

 

Can you be more precise on the problem you are having?

 

If you are looking for any available PCIe driver that is provided by XIlinx, the AR may help you.

If you are looking for a way that you can test your EP device without a driver, you can use PCITree for testing the device.

Hope this will help you.
