// MMU_SetMTT(0x00000000,0x07f00000,0x00000000,RW_NCNB); //bank0
MMU_SetMTT(0x00000000,0x00100000,(U32)__ENTRY,RW_CB); //bank0 when no nor flash, must do this
//!!! Important note, redirect IRQ vector to reset entry !!!
MMU_SetMTT(0x04000000,0x07f00000,0x00000000,RW_NCNB); //bank0
这是摘自示例程序的几行代码
为什么一定要把0x00000000-0x00100000映射到(U32)__ENTRY(0x30000000),还说//bank0 when no nor flash, must do this?
为什么说//!!! Important note, redirect IRQ vector to reset entry !!!?
为什么0x04000000映射到0x00000000,使得访问NOR flash时要用0x04000000?
