Hi,

  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.

 

Regards.
