[U-Boot-Users] Running U-boot in cache area.

    I am tring to run U-boot on MIPS 24KE processor.
      I have done MIPS 24KE cache initilization and configured it for write through  mode in the start.S file.
  If I specify SDRAM start address  as uncached area ( start with 0xa0000000), u-boot boots up and able to get the u-boot prompt.
  It I try SDRAM start address as cached area ( Start with 0x80000000), the u-boot comes up to relocation function and hangs.
  Could you please tell me what could be the problem.
  Did i mss any thing?.
  I see the same behaviour with write back mode also.
  Should i call any cache invalidation ( doing this as part of cache initilization in the start.S) or flush functions before calling relocation().
  I am  enabling primary cache only and no secondary cache.
  Thanks in advance.
