Building SPL/u-boot to boot from SD on i.MX 8M QUAD EVK

I am trying to build SPL/u-boot from  source code and boot from SD, but SPL gets stuck in lpddr4_800M_cfg_phy() when calling wait_ddrphy_training_complete().

I am building the code from https: // , branch is imx_v2017.03_4.9.51_imx8m_beta.

I am using the imx8mq_evk_defconfig configuration. Below is the SPL output.

Any idea what am I missing?


Thank you,
