I was able to build an updated rpi-firmware port based on 1.20210805 and this boots successfully on pi400 as well as rpi4. With this, I can load the rpi-poe-plus overlay and I just need to try and reverse engineer the undocumented mailbox API by reading the Linux code. diff --git a/sysutils/rpi-firmware/Makefile b/sysutils/rpi-firmware/Makefile index e82ab20ebc74..4fbb5df6d743 100644 --- a/sysutils/rpi-firmware/Makefile +++ b/sysutils/rpi-firmware/Makefile @@ -1,5 +1,5 @@ PORTNAME= rpi-firmware -PORTVERSION= 1.20210303.g20210303 +PORTVERSION= 1.20210805.g20210805 CATEGORIES= sysutils MAINTAINER= [email protected] @@ -17,7 +17,7 @@ USE_GITHUB= yes GH_ACCOUNT= raspberrypi gonzoua:pscimon GH_PROJECT= firmware rpi3-psci-monitor:pscimon -FW_TAG= fcf8d2f +FW_TAG= 8939bde PSCI_TAG= 558620c GH_TAGNAME= ${FW_TAG} ${PSCI_TAG}:pscimon diff --git a/sysutils/rpi-firmware/distinfo b/sysutils/rpi-firmware/distinfo index 2e1e0c92066a..27a0eb8c9fa3 100644 --- a/sysutils/rpi-firmware/distinfo +++ b/sysutils/rpi-firmware/distinfo @@ -1,5 +1,5 @@ -TIMESTAMP = 1614939753 -SHA256 (raspberrypi-firmware-1.20210303.g20210303-fcf8d2f_GH0.tar.gz) = 5a0d7247490e0207f0fc32baabcec25a0e97ebdab9cbee216bf9537a1de22e69 -SIZE (raspberrypi-firmware-1.20210303.g20210303-fcf8d2f_GH0.tar.gz) = 192233875 +TIMESTAMP = 1683975782 +SHA256 (raspberrypi-firmware-1.20210805.g20210805-8939bde_GH0.tar.gz) = 2069df5b1dff340c78e393e4cc10feba395524d26cf5db475876d62b7a0507b2 +SIZE (raspberrypi-firmware-1.20210805.g20210805-8939bde_GH0.tar.gz) = 193244754 SHA256 (gonzoua-rpi3-psci-monitor-558620c_GH0.tar.gz) = 7621db7933eedaa17a03c282ef8a50be597bd14366149dfa93172d1b3985dbb7 SIZE (gonzoua-rpi3-psci-monitor-558620c_GH0.tar.gz) = 5614 diff --git a/sysutils/rpi-firmware/pkg-plist b/sysutils/rpi-firmware/pkg-plist index 7661a0a13cb2..02a41640a0be 100644 --- a/sysutils/rpi-firmware/pkg-plist +++ b/sysutils/rpi-firmware/pkg-plist @@ -183,6 +183,7 @@ %%DATADIR%%/overlays/rpi-display.dtbo %%DATADIR%%/overlays/rpi-ft5406.dtbo %%DATADIR%%/overlays/rpi-poe.dtbo +%%DATADIR%%/overlays/rpi-poe-plus.dtbo %%DATADIR%%/overlays/rpi-proto.dtbo %%DATADIR%%/overlays/rpi-sense.dtbo %%DATADIR%%/overlays/rpi-tv.dtbo On Fri, 12 May 2023 at 18:41, Mark Millard <[email protected]> wrote: > On May 12, 2023, at 10:19, Mark Millard <[email protected]> wrote: > > > On May 12, 2023, at 10:11, Mark Millard <[email protected]> wrote: > > > >> On May 12, 2023, at 09:38, Doug Rabson <[email protected]> wrote: > >> > >>> On Fri, 12 May 2023 at 17:27, Mark Millard <[email protected]> wrote: > >>> On May 12, 2023, at 08:43, Doug Rabson <[email protected]> wrote: > >>> > >>>> I have a pi4 with the official POE+ hat which I want to run FreeBSD > on.
