issue with A10 GSRD v17.1 (A10 SOC FPGA) Error "couldn't calibrate SDRAM"

[Matt1]

Hi,

i was trying to boot the HSP using the reference design available in rocketboards using SDMMC.

as there are some display ips available in the reference design which i didnt have license i removed it and generated the binary files.i followed the process what is explained in the rocket boards.

But i am getting an error "couldn't calibrate SDRAM"

can somebody suggest some work around.

the project is not a custom design actually its a reference design from rocket boards v19.3.

thanks in advance .

Hi,

Could you provide the Quartus Version you are using?

Also, which Rocketboards link did you follow? Is it possible for you to provide the link so I can check if that is the correct version for you reference.

You may also provide the booting logs here, that would help.

Based on your comments, I assume that the version of the design you have downloaded is and your Quartus are not identical. Using different version of Quartus and reference design is not recommended.

If you are using Quartus Version 19.3, you may get the pre-built image here:

If you want the sd card pre-built image, the file name is "sdimage.tar.gz" in the above link, and select in the table Arria 10 GHRD Design.

hello el.ign,

yes..i was using Quartus prime18.0 but the project was the latest one 19.3.

i have solved the issue by downloading the 18.0 reference design.

thanks for the support.
