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

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. Sathesh
