Subject: [U-Boot-Users] [Q]MPC8245 Extended Rom Setting
Date: Thu, 31 Jul 2003 16:11:02 +0900	[thread overview]
Message-ID: <000f01c35732$e7132a00$240110ac@jsbae> (raw)



i want to access extended rom area (0x70000000) in mpc8245 sandpoint board (ARTis Microsystems A-3000)
i tried to reallocate BAT1(initial stack area ) 0x40000000 to 0x70000000 but board was hang...
i wrote BAT1 reallocation function and call BAT1 reallocation function in board.c ( board_init_r () )

 void move_bat1 (void)
    {
    mtspr (IBAT1L, (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT));
    mtspr (IBAT1U, (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP));

    mtspr (DBAT1L, (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT));
    mtspr (DBAT1U, (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP));
    __asm__ __volatile__("eieio");
    __asm__ __volatile__("isync");
    __asm__ __volatile__("sync");

}

i think ram use stack at this function so 0x40000000 nerver accessed 

what's wrong... :-((

^^ best regard~~
