The phyCORE
‑
i.MX 6UL/ULL provides one green user LED (D2) on board
. It can be controlled by setting GPIO5_4
to the desired output level. A high-level turns the LED on, a low-level turns it off.

14. If the phyCORE-i.MX 6UL/ULL is equipped with the i.MX 6UL/ULL version G3 supporting tamper detection,
J11 needs to be set to 1+2 and 3+4 to connect GPIO1_8 to the USER_LED, because tamper detection
GPIO5_4 can only be used as an output with G0 to G2 and Y0 to Y2 controller versions.
