NetFPGA SUME - DDR3B acceptance test fails

Question

Hello,

I'm with problem in the acceptance test.  When I run acceptance test, the DDR3 test fail. In the reference manual (git hub NetFPGA SUME) is describe that tests with memory can to fail. The test log (figure in attach) shows the message "ddr3: Calibration Failed".  I executed the  test a lot times and  the error continued appearing. That is a problem with hardware? How I can solved?

Thanks.

Hello @Racyus Delano,

I would instead recommend working with the NetFPGA group as they have a lot more dedicated experience with the SUME board than any of us here at Digilent; the sign-up for that community is available here if you are not already a part of it. Digilent will be able to help you more with the hardware errors and what can be done about it if that group is unable to help you. I do know that the recommended version of Vivado for running the SUME acceptance tests is 2016.4 as improvements to the MIG were made in that version to help mitigate any false negatives that were generated during the tests.

Thanks,
JColvin
