I wonder the timing of gpioRI exported.
I entered “AT!RIOWNER=1” and power off on WP7605.
Then, I checked gpioRI exported or not, using “ls /sys/class/gpio”.
Unfortunately, sometimes it does not exist gpioRI.
However, it returned “1”, when I entered “AT!RIOWNER?”.
Is it too fast power off after entering “AT!RIOWNER=1” to change controll core?
How long seconds must I wait for being changed it?
