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.
