i.MX 91 failing LPDDR4 Calibration

[Ranjit131185]

Hello, I've got a custom board using i.MX 91 and 16Gbit LPDDR4 (Micron MT53E1G16D1FW-046 WT:A).

We do have DDR tool "i.MX_CFG_v13_EAR1_MX93" and USer guide as "DDR tool User Guide_v13_EAR1".
Using this we have geberated the ddr_timing.c file. This ddr_timing.c file we have used in spl_uboot for DDR
configuration in lpddr4 mode.

We able to build the uboot. but after power on we getting stuck un spl_uboot only as below

"
U-Boot SPL 2022.04-lf_v2022.04+g73b88f0342 (Mar 01 2023 - 07:35:40 +0000)
SOC: 0xa0009300
LC: 0x40010
M33 prepare ok
Trying to boot from BOOTROM
Boot Stage: Primary boot
Load image from 0x48c00 by ROM_API
NOTICE: BL31: v2.6(release):lf-6.1.1-1.0.0-0-g616a4588f

"

Note :
1. We dont have RPA for iMX91
2. We have used DDR tool "i.MX_CFG_v13_EAR1_MX93" for ddr_timing.c file creation

Could you please suggest input so that we can configure the lpddr4 mode and want to boot iMX91 ?

Still I am not able to resolve this issue

Hi @Ranjit131185,

I hope you are doing well.

Please make sure that you have performed DDR validation as mentioned in 4.3 DDR validation in User Guide for Config Tools for i.MX

Could you please mention which UART port is used for debug console?

Thanks & Regards,
Dhruvit Vasavada

Yes, I did the lpddr4 and lpddr4x mode validation.

log are as below
