Thanks for you reply.

I think It's relate to the DMM LISA MAP and DDR3 timing configure.

I have two board, One is used 4x128M DDR3 (K4B1G1646G-BCH9), other is used 2x256M DDR3(K4B2G1646G-BCH9); And the result(at same test env), the first camera is ok, and the second camera often happend RSZ OVERFLOW.

The first camera configure(default value of IPNC3.2), 4x128 DDR3

#define PG2_1_DMM_LISA_MAP__0 0x0
#define PG2_1_DMM_LISA_MAP__1 0x0
#define PG2_1_DMM_LISA_MAP__2 0x805C0300
#define PG2_1_DMM_LISA_MAP__3 0xA05C0300

/* TI814X DDR3 EMIF CFG Registers values 400MHz */
#define DDR3_EMIF_READ_LATENCY 0x00170208 //RD_ODT=0x2, IDLE_ODT=0x0, Dynamic power_down enabled
#define DDR3_EMIF_TIM1 0x0AAAD4DB
#define DDR3_EMIF_TIM2 0x682F7FDA
#define DDR3_EMIF_TIM3 0x501F82BF
#define DDR3_EMIF_REF_CTRL 0x00000C30
#define DDR3_EMIF_SDRAM_CONFIG 0x61C011B2
#define DDR3_EMIF_SDRAM_ZQCR 0x50074BE1

**And the second *camera configure(configure by myself), 2x256 DDR3 connect to EMIF0, using the same timing configure.***

In order to in reduce the jointing cost, we want to using 2 pieces of DDR3.

#define PG2_1_DMM_LISA_MAP__0 0x805C0100
#define PG2_1_DMM_LISA_MAP__1 0xA05C0100
#define PG2_1_DMM_LISA_MAP__2 0x0
#define PG2_1_DMM_LISA_MAP__3 0x0
