Bug ID: 214337
Summary: RPI-B: create separate device tree for RPI-B+
Product: Base System
Version: 11.0-STABLE
Hardware: arm
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
The RPI-B and RPI-B+ are slightly different. The Linux sources for the FDT
recognize this, as evidenced by running
# diff /usr/src/sys/gnu/dts/arm/bcm2835-rpi-b{,-plus}.dts
The FreeBSD version in /usr/src/sys/boot/fdt/dts/arm/rpi.dts seems to cover the
RPI-B, but not the B+. Amongst others, this makes it impossible to use the
activity and power LEDs, and may even lead to hardware problems when trying to
modify the activity LED.
It would be nice to have a dts which is suitable for the RPI-B+.
This possibly means that all the RPI variants allegedly supported by rpi.dts
actually need their own specific dts.
