cat /sys/module/ec_sys/parameters/write_support shows

Y

But still there is no directory /sys/kernel/debug/ec/ :

sudo ls -l /sys/kernel/debug/ec/
ls: cannot access '/sys/kernel/debug/ec/': No such file or directory
sudo ls -l /sys/kernel/debug/ec/ec0/io
ls: cannot access '/sys/kernel/debug/ec/ec0/io': No such file or directory

How to fix this issue?
