How to operate GPIO on and off in sysfs.Please help me

I have an UP2 Intel N4200 evaluation board.I use Ubilinux sysfs shell can operate GPIO on and offreference https://wiki.up-community.org/Pinout_UP2.But after I installed Ubuntu 18.04, in the same way, no error was reported on the shell command, but in fact GPIO did not work.
[CODE][root@test-UP-APL01:/sys/class/gpio# echo 432 > export
root@test-UP-APL01:/sys/class/gpio# cd gpio432
root@test-UP-APL01:/sys/class/gpio/gpio432# echo "out" > direction
root@test-UP-APL01:/sys/class/gpio/gpio432# cat value
0
root@test-UP-APL01:/sys/class/gpio/gpio432# cat value
1
root@test-UP-APL01:/sys/class/gpio/gpio432# echo 1 > value

I really can't find the problem point, how to operate GPIO on and off in sysfs.Please help me,Thank you
