how to directly control the WR703N's LED ?
I direct write the ar9331's gpio27 as following :
1.
the address 0x18040000 : GPIO_OE , bit 27, to 1, enabled it.
2.
the address 0x18040008 : GPIO_OUT , bit 27, switch between 1 and 0 , try to swap the LED , but I failed.
3.
so , I write the address 0x18040028 , GPIO_FUNCTION_!,
bit 25, ETH_SWITCH_LED_DUPL, --> 0
bit 24 , ETH_SWITCH_LED_COLL, --> 0
bit 23 , ETH_SWITCH_LED_ACTV, --> 0
bit 7 , ETH_SWITCH_LED4_EN, --> 0
bit 6 , ETH_SWITCH_LED3_EN, --> 0
bit 5 , ETH_SWITCH_LED2_EN, --> 0
bit 4 , ETH_SWITCH_LED1_EN, --> 0
bit 3 , ETH_SWITCH_LED0_EN, --> 0
but , still nothing happens to the LED,
so, I don't know what happens.
I guess some bit , work as the top switch of the LED0-LED8 array, maybe exist and I have NOT touch.
Anybody know which register I forgot to write ?
