The SD card moves over as is, so: - pi_standard_setup can install the Pi 5 kernel (linux-image-rpi-2712, an arm64 package on the armhf userland), which a Pi 4 image lacks. Opt-in via pi_standard_setup_install_pi5_kernel. - The Pi is powered through the HiFiBerry board's GPIO header, so it cannot negotiate a 5A supply and would cap USB at 600mA. pi_hifiberry_amp sets usb_max_current_enable=1 when hifiberry_powers_pi is true (default false). - The DHT22 poller is off: Adafruit_DHT bit-bangs BCM283x registers, which the Pi 5 no longer has (GPIO sits behind the RP1 chip).

# pi_hifiberry_amp
|
|
|
|
Deactivates the Pi's onboard analog audio and activates a HiFiBerry
|
|
amp/DAC overlay instead.
|
|
|
|
**Key vars:** `hifiberry_overlay`, `hifiberry_powers_pi`
|
|
|
|
`hifiberry_powers_pi` (default `false`) is for a Pi fed through the HiFiBerry board's
|
|
GPIO header. On a Pi 5 that sets `usb_max_current_enable=1`, or USB is capped at 600mA.
