DDR3 narrow mode error issue on the DM385 IPNC Kit

Other Parts Discussed in Thread: DM385

Dear all,

我們想要在DM385 IPNC reference design kit上改用NARROW mode,將DDR3的Data bus width由32 bits改成16 Bits。

我們把原本DDR3(533MHz)之中的參數SDRCR(DDR3_EMIF_SDRAM_CONFIG)設定由0x61C11A32改成0x61C15A32。

在IPNC kit上執行Pre-build的uImage與UBIFS時,會產生Timeout Error(如下)而無法開機。
