Hi, I am new to U-Boot and I get some questions when i port U-Boot to my board with lpc2220 the memory map is 0x00000000->interrupt table 0x40000000->internal ram 64K 0x80000000->external nor flash 8M 0x81000000->external ram 1M and TEXT_BASE=0x81000000 i use H_jtag to burn my u-boot.bin to 0x80000000 , then start my board,the code at 0x80000000 in flash first copy itself to 0x81000000 , and remmap the interrupt table to 0x80000000,so far I think the code is running ok but the questions are: 1 what is the monitor_flash_len meaning for, I wander what the "moniter" is? 2 what the address can i set the CFG_MONITOR_BASE

please help is there anyone doing the same work as mine
