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

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:

Please use shorter lines!

[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;

Please read the processor manual, memory controller section. Try to understand what happens when you write to the BR and OR registers, and why strange things may result if you change one but not the other (like you see when you add code right between these two statements).
