Other Parts Discussed in Thread: SYSBIOS
Tool/software: TI-RTOS
Hi,
We are using VSDK3.03 source on Tda2px EVM C rev based customized HW.
Here, we are using 4GB Micron DDR3. For this ,we have configured LISA and DMM EMIF register as below mentioned :
ti_components/drivers/pdk_01_09_00_17/packages/ti/boot/sbl_auto/sbl_utils/src/tda2xxsbl_utils_tda2px_ddr_config.c
#if (TDA2XX_EMIF_MODE == SBLLIB_DUAL_EMIF_2X1GB)
{
SBLLibPrintf(SBLLIB_TRACE_LEVEL_IMP_INFO,
" Two EMIFs 1GB each (Total = 2GB)\n");
/* MA_LISA_MAP_i */
HW_WR_REG32(SOC_MA_MPU_CONF_REGS_BASE + LISA_MAP_0, 0x80700200U);
HW_WR_REG32(SOC_MA_MPU_CONF_REGS_BASE + LISA_MAP_1, 0xC0700100U);
/* DMM_LISA_MAP_i */
HW_WR_REG32(SOC_DMM_CONF_REGS_BASE + LISA_MAP_0, 0x80700200U);
HW_WR_REG32(SOC_DMM_CONF_REGS_BASE + LISA_MAP_1, 0xC0700100U);
}
#endif
As we know that SYSBIOS has an 1GB DDR size limitation on per EMIF so , Is there any implication if we configure 2GB on per EMIF when we have total 4GB DDR size?
What is pros/cons , If we configure 1GB DDR on per EMIF even though we have availability of 2GB DDR on per EMIF ?
Can we configure like as LISA_MAP_0 – >EMIF2 and + LISA_MAP_1 -> EMIF1 ,this order makes any impact?
What will be advantage when we configure interleaved LISA map in MA_LISA_MAP and DMM_LISA_MAP ?
Will it impact on performance ?
