[U-Boot-Users] can't light led after flash restrict to preliminary range

[刘辉]

hello all:
	
	I am new for U-boot and try to port uboot base one TQM866M to my board. I meet a problem and I don't know how to sovle it. Here is the situation:
	
	I light a led in cup_init.c -> cpu_init_f( ) as flow:

[174]	led_init(0x7);	/* here is my light led function*/
[175]	/* now restrict to preliminary range */
[176]	memctl->memc_br0 = CFG_BR0_PRELIM;
[177]	memctl->memc_or0 = CFG_OR0_PRELIM;

	And I succeed. But when i move the led function down to line 177 or even to 176, the led doesn't work, as flows:

[174]	/* now restrict to preliminary range */
[175]	memctl->memc_br0 = CFG_BR0_PRELIM;
[176]	led_init(0x7);	/* here is my light led function*/
[177]	memctl->memc_or0 = CFG_OR0_PRELIM;

	Here is the short discription of my board:
	MPC859DSL
	OSCLK
	AM29lv320mb * 1, CS0, 4MByte
	IC42S16800-t *2, CS1, 32Mbyte

	I didn't change any words of the tqm866.h, because I thing that:
	1. althoung I have only one flash chip, while tqm866m has tow and memc_or1 was set in line 168, but it doesn't take into use.
	2. the or and br belong to ram don't take into use at this moment, too.

	i don't have a debuger like IDE2000, so i was so confused. 
	hope you can help me.

	regards.
