I port u-boot to magicarm board based on lpc2290, this board has a nor flash whose address range form 0x80000000 to 0x801fffff
ram address(0x81000000-0x817fffff). I modified the micro TEXT_BASE to 0x81080000 and dowmload the u-boot.bin into the flash. the u-boot doesn't work at all . when i modified the micao TEXT_BASE to 0x80000000 and download to flash ,it only work for a while and soon collapsed . who can tell me what the problem is.
this is the ld sccript

OUTPUT_FORMAT("elf32-littlearm", "elf32-littlearm", "elf32-littlearm")
OUTPUT_ARCH(arm)
