Dear NXP,
I have a srg_imx8mplus platform (base : imx8mplus).
(1) Please check the MX8M_Plus_LPDDR4_RPA_4G_RAM.xlsx.
(2) Use MSCALE_DDR_Tool to do DDR calibration and stress test . Test result : PASS.
(3) Update the new lpddr4_timing.c and imx8mp_evk.h .
(4) ../include/configs/imx8mp_evk.h modify as follows:
#define PHYS_SDRAM_SIZE 0x80000000 /* 2 GB */
#define PHYS_SDRAM_2_SIZE 0x80000000 /* 2 GB */
(5) srg_imx8mplus can boot successfully.
(6) Please help me to check the content of LPDDR4_RPA_4G_RAM.xlsx. Is it correct ?
(3) About this imx8mp_evk.h modification, is it correct ?
Dear NXP,
I have fixed this issue. Thank you!
Dear NXP,
Please check my imx8mp_evk.h . My modifications are as follows:
/* Totally 6GB DDR */
#define CONFIG_SYS_SDRAM_BASE 0x40000000
#define PHYS_SDRAM 0x40000000
#define PHYS_SDRAM_SIZE 0xC0000000 /* 3 GB */
#define PHYS_SDRAM_2 0x100000000
#ifdef CONFIG_TARGET_IMX8MP_DDR4_EVK
#define PHYS_SDRAM_2_SIZE 0x40000000 /* 1 GB */
#else
#define PHYS_SDRAM_2_SIZE 0x40000000 /* 1 GB */
#endif
U-boot displays the following messages:
Model: NXP i.MX8MPlus LPDDR4 EVK board
DRAM: 6 GiB
Please tell me how to modify.
Dear NXP,
I want to know the answer. Can you tell me as soon as possible.
one can look at example below for "IMX8MP_DDR4_EVK"
Best regards
igor
Dear NXP,
May you provide define HYS_SDRAM_SIZE value ,and define PHYS_SDRAM_2_SIZE value to me ?
Dear NXP,
Although it can be successfully booted, rsync the SD card data to emmc. The following message appears:
root@imx8mm-bse:~# rsync -avAX /* /tmp/rootfs/ --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found,/reserved/*,/boot/*}
sending incremental file list

[ 87.999869] ESR: 0x02000000 -- Unknown/Uncategorized

Are these messages related to the LPDDR4 setting?
Hi Albert
.xlsx seems as correct. For imx8mp_evk.h suggest to leave "PHYS_SDRAM_SIZE" in default value,
change only "PHYS_SDRAM_2_SIZE".
