Arria10 SoC DDR4 Interface calibration failed at the stage "write per-bit deskew", is there any Intel employee or FPGA customer knows the reason?
PCB design problem?
Power supply problem?
Time parameter problem?
Pin assignment problem?
FPGA IO termination problem?
Or anything else?
I'll be appreciated if anyone can help me loacte the problem so I can update software or hardware.
There are a lot of reasons that can cause DDR4 calibration failure. For example as below:
I hope this helps.😊
Have you solved your problem about JTAG interface
How did you solve it？
I have the same problem as you.
I'll be appreciated if you can tell me the answer.
If your JTAG circuit is correct, probably beacuse your download cable doesn't support Arria10. I suggest you to change to a newer download cable, and it's better to be produced by Altera.
The problem has been solved.I changed a USB BLASTER II. THANKS!
I have a new problem.
When I download jjc file to EPCQL1024 through JTAG interface, an error occurs "Error (209014): CONF_DONE failed to go high in device".
Observe DCLK with an oscilloscope and find that there is no clock and nCSO is not pulled down.(EPCQL1024 replaced by MT25QU01G)
Have you ever had such a problem？
