I am trying to port u-boot for MALTA(mips) board. The code downloads properly at the appropriate Flash address (0xBFC0000) but then loops back at some point due to memory problems.

If you know that what you see is being caused by memory problems then you should fix those memory problems, right?

here is the dump file -

...

ffffffffbfc00300: 10000090 b ffffffffbfc00544

<romExcHandle> > ffffffffbfc00304: 241a0300 li $k0,768

ffffffffbfc00544 <romExcHandle>: ffffffffbfc00544: 1000ffff b ffffffffbfc00544

Other boot loaders works ok. that means hardware is working perfectly fine. Any pointers would be helpful.

If you come trhough 0x300 you should find out why you see a cache vector exception.
