I am trying to run the RAMTester sample for the XEM7010-A50. It is not working for me using both the regenerated bitstream, and generating it myself. Using the generated bitstream, I get the following output:

And so on for all 10 tests.
When build the bitstream myself by upgrading the IPs and using the provided Verilog files, the memory controller fails calibration (the init_calib_complete signal never goes high). I noticed some strange inconsistencies:
-
The provided bitstream has 0 for the calibration
CAPABILITYlocalparam (connected to endpoint 0x3e) when the value is 1 for the provided verilog file (Ubuntu 22 FrontpanelSDK). -
On the recommended MIG settings in the XEM7010 documentation, the memory part is MT41K256M16XX-125. After doing a parts lookup on the Micron website, the memory part on my board is MT41K256M16TW-107:P, which corresponds to a different memory part selection in the MIG. After trying this memory part, I still cannot pass calibration when I build the bitstream.
It seems the only reason the provided bitstream passes calibration is that it claims it is incapable (endpoint 0x20 is 0), so it just skips it. I don’t understand what the purpose of memory calibration is or if that will even cause the problem with accessing memory, but I am at a loss.
Any help would be appreciated!
