I,m using MPC8315 and set immr WIMG to b0101. But uart got problem.

it work well before enable icache and dcache.

after enable icache and dcache,it not work.

I missed something?

valueu = MAKE_BATU( 0xe0000000, MAKE_BL( 1 * 1024 ), 1, 1 );//1M for IMMR

valuel = MAKE_BATL( 0xe0000000, 0, 1, 0, 1, 2 ); //WIMG = b0101

	MOVE_TO_SPR( SPR_IBAT2U, valueu );
	MOVE_TO_SPR( SPR_IBAT2L, valuel );
	MOVE_TO_SPR( SPR_DBAT2U, valueu );
	MOVE_TO_SPR( SPR_DBAT2L, valuel ); Enable_ICache(); Enable_DCache();

What is the exact (binary or hexadecimal) value you are writing to BATs?
