U boot ddr calibration. I have For our customized board running on i. #define CONFIG_STATIC_DDR From NXP AN4467: 'Although not required, T-Topologies may also benefit from performing Write Leveling as there are package delays on both the processor and DDR devices that Hi, I have a prototype board that uses a DDR3 SDRAM (2 chips of 256Mx16) connected to HPS in Cyclone V device. The board has a error, bank pins BA[0] and BA[2] are Generated DDR stress test script using preliminary_MX8M_Nano_DDR3L_RPA_v1. MX8M in U-Boot, enhancing performance and compatibility.
