[U-Boot-Users] problem on magicarm board based on lpc2290 cpu

18 Jun 2006


      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)
ENTRY(_start)
