UM10503 ( says that in RBC (high-performance) mode content of the mode register must be shifted additionally by the number of bank select bits. SDRAM initialization code in emc_18xx_43xx.c does not perform this shift. So the solution is to use BRC mode only (EMC_DYN_CONFIG_LPSDRAM) or to fix the driver like I did. My fix is attached below.
