Hi, I am trying to bring a board with i.MX21s processor, but it fails when I try to initialize SDRAM to load bootloader.I am using Infineon's Mobile DRAM (HYE18L256160BF). The failure happens when I to set the precharge all command. The command is done by writing 0x92120300 to the SDRAM contol register (0xDF000000). However, when reading the register back, I get the value of 0x12120300
