Hi Hongliang

 

since all trainings are with errors, one can check with oscilloscope if there are any signals

on memory. Also recommended to use latest MX8DualX_C0_B0_LPDDR4_RPA_1.2GHz_v16.xlsx on

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8QXP-DXP-DX-DDR-Register-Programming...
