Orangepi PC: Read PA15 and map to PA7

kelvinlo0223

I am using Orangepi PC;Orangepipc_2.0.8_ubuntu_focal_desktop_linux5.4.65;

I wonder if there is any method (by linux command) to:
(1) read the logic of PA15 (STATUS_LED), connected to green LED, and then
(2) map the result of (1) to EXT Port PA7 as output.

Many thanks for help!
