Are you running under root ?
Try it from bash under root user.
Code:
# cd /sys/class/gpio
# ### chose pin to use - pinheader pin 11 == GPIO1_C6 == should be CPU pin 54 (1*32+2*8+6)
# echo 54 > export
# ls gpio54
active_low  device  direction  edge  power  subsystem  uevent  value
# echo out > gpio54/direction
# echo 0 > gpio54/value
# echo 1 > gpio54/value
# echo 0 > gpio54/value
# echo 1 > gpio54/value
# echo in > gpio54/direction
# cat gpio54/value
# echo 54 > unexport
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" Angry. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
