Subject: [PATCH] overlays: rpi-poe-plus: Improve the cooling levels
|
|
|
|
The PoE HAT cooling levels are not well suited for the PoE+ HAT - the
|
|
fan fails to come on until the temperature reaches the third trip point
|
|
(50C).
|
|
|
|
Give the rpi-poe-plus overlay a different set of cooling levels -
|
|
0 32 64 128 255, as suggested by @chris-kai-in.
|
|
|
|
See: https://github.com/raspberrypi/firmware/issues/1607
