C6202: Why EMIF is not active?

Started by tangsword January 22, 2003
We connect a POWERPC to C6202's expansion bus. So we choose the XBUS
boot mode for C6202. But when we finished initializing the
C6202's external memory configuration registers -- EMIF CE0 space
control through the XBUS interface, the CE0 is not active for refresh
SDRAM. And the same reasion,C6202 is dead when access CE1,CE2 memory

The same result got when through the C6202's JTAG.
So what's happened to C6202's EMIF?
