This is the memory map how depicted by the datasheet: 0x00000000--0x7fffffff KUser - Cached / Mapped 0x80000000--0x9fffffff KSEG0 - Cached / Unmapped 0xA0000000--0x9fffffff KSEG1 - Uncached / Unmapped .... I think that on my application the UNCACHED_SDRAM should map the address on KSEG1 (how it is now) but this simply doesn't work. Instead, using the PHYSADDR(a) macro... the kernel is able to start. I suspect that there are issues on cache management. Can be?
