Occasional ContributorHello,
Below action can be implement to see if anything help.
1. You can use the original qts to test, no need to update.
2. Lower the EMIF clock frequency to 933Mhz.
3. Disable address/command calibration step one by one shown as below.
New ContributorHi @ybin ,
Thank you for your response.
1) I am using Quartus pro 19.4 in our system. The HILO module will need to be integrated into our system later. Therefore, I don't see any reason to downgrade the Quartus from 19.4 to 18.1 just for testing for memory module.
2) The example design is using 1066 MHz. Does lower EMIF clock to 933 MHz mean the example design was not correct?
3) The example design already disabled that setting.
Thanks
Occasional ContributorHi,
To lower the frequency is just to have a test, to see if lower frequency is effect.
To disable/skip address/command calibration step is to enable the highlight setting. Pls make sure you follow it. If all the 3 actions you are implement, please let me know the result.
New ContributorHi,
Lowering the frequency to 933 or 933.3333 caused error as shown below
I also made the test with
- Skip address/command leveling
- Skip address/command leveling & deskew
None of them works.
Thanks
Occasional ContributorHi,
I check the development kit bts setting, I find that the type of DDR4 is UDIMM. Can you check your board's DDR4 type from the part number? To see if it's the same as BTS setting.
BTW, you compiled BTS and test it, not just use the sof from the download package, Is that right?
