I am follwing along the [GSRD for the S10 SoC][https://rocketboards.org/foswiki/Documentation/S10GSRDBootLinuxFromSDCard180] with a Stratix 10 SX SoC development kit and am having difficulty on step 8. When U-Boot begins, it quickly fails with the error
Error as SDRAM calibration failed.
I haven’t modified any of the GSRD at all and I have the DDR4 memory card in the HPS memory socket. I am using Quartus Prime 18.1.2.
Does anyone have any advice on how to fix such errors or debugging strategies?
