Pocket beaglebone PIN P2-24(GPIO44) Working issue.

I have write code for my project in that code operate GPIO 44, High-Low operation.

When I restart pocket beaglebone and execute code GPIO 44 Voltage level remaining 1.7V (Not operate properly).

Then stop execution and again execute code GPIO 44 Voltage level 3.3V and 0 V operate properly.

What is issue with GPIO44 on every restart it’s not giving High-Low operation properly.
