I think the new gpio driver(after r38026(include)) of ramips platform has some bugs, after i set uartf to "gpio uartf" mode, i can't export any gpio. Maybe there are some relationship between this error and mine.
root@OpenWrt:/sys/class/gpio# echo 1 > export [ 1056.700000] rt2880-pinmux pinctrl.1: pin 1 is not set to gpio mux [ 1056.720000] rt2880-pinmux pinctrl.1: request() failed for pin 1 [ 1056.730000] rt2880-pinmux pinctrl.1: pin-1 (pio:1) status -22 ash: write error: Invalid argument
