[U-Boot-Users] U-boot for Malta

[calvin]

Hi,

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.
here is the dump file -

 > ffffffffbfc00300:       10000090        b       ffffffffbfc00544 
<romExcHandle>
 > ffffffffbfc00304:       241a0300        li      $k0,768

ffffffffbfc00544 <romExcHandle>:
ffffffffbfc00544:       1000ffff        b       ffffffffbfc00544 
<romExcHandle>

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

Thanks and regards,
Pooja

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

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