Release: Yocto-Morty (4.9.51_GA)
Board: i.MX8MQ EVK
I want to know at which frequency LPDDR4 is working on iMX8MQ EVK board?
I have downloaded LPDDR4 RPA from iMX8MQ DDR stress tool v2.1 and generated ddr_init.c & ddrphy_train.c with same configurations for 3GB DDR on iMX8MQ EVK board.
1) Using default ddr_init.c & ddrphy_train.c files in u-boot, system boot ups properly.
2) After changing ddr_init.c & ddrphy_train.c files which are generated from DDR stress tool, board boot up stuck at the kernel level. We are using the EVk only & only these two files are changed.
Can you please provide your inputs. I have attached files which I was taken as reference for DDR configurations. Also, I have attached ddr_init.c & ddrphy_train.c files which I have used for both cases.
(NOTE: Calibrations are passed successfully with these changes)
