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