Hi @allen18,


May I check with you on the following items?:

1. Can you please check if the PCIe linked up successfully when the error occurred?

2. Are you using an Altera development kit or a custom board?

3. Could you please share the .ip file, so that I can generate the Example Design based on the parameters you specified?

4. Is this a root port or an endpoint design?

5. Are you using the 'DMA' Example Design?

6. Which PCIe Gen is used in the Example Design?


Thanks.

Best Regards,

Ven

    Hi @ventt ,

    I'm not sure if the DMA timeout is due to the PCIe link down. I suspect it's not.

    I'm using a custom board,endpoint design, the relevant IP files are attached. The platform design file is simply the example design.
