Dear all,
We want to read the Mode Registers during LPDDR4 operation to optimize the values of VREF_CA and VREF_DQ in RPA.
Are there any resources available for reference?
Best Regards,
George

Hi George
seems this could be done using MRCTRL registers described in
sect.9.3.3.1.6 Mode Register Read/Write Control Register i.MX8M Reference Manual
for example one can look at lpddr4_mr_read() in
ddrphy_utils.c\imx8m\ddr\drivers - uboot-imx - i.MX U-Boot
Best regards
