Please see https://wikidevi.com/wiki/Broadcom under the SDIO section. The t=

Sorry for the top post.=C2=A0

I said similar or the same, I don't have a lot of bandwidth to check these =
things right now.=C2=A0

SDIO (the hardware interface for both chips) is not currently supported by =
the FreeBSD kernel and there does not seem to be support for the underlying=
 Broadcom chips (as there is no SDIO support!), but Mr. Adrian Chadd may be=
 able to speak more to that. =E2=80=8EHe has previously mentioned that the =
chips are very complex and porting them will be time consuming.=C2=A0

There is currently a new SDIO driver making its way into the head branch bu=
t it will not be in FreeBSD 11. Mr. Warner Losh could speak more to that.=
=C2=A0

Please see =E2=80=8Ehttps://reviews.freebsd.org/D4761 for more details on t=
he new CAMMMC driver.=C2=A0

As I am not a hardware/FTD expert, I would guess that the issue you are see=
ing is the same both ways: the phat is modifying the hardware signature of =
the device, causing the dtb to fail to load. =E2=80=8EBut that's just a gue=
ss.=C2=A0

Hi!

The saga continues. Under Raspbian, I upgraded the pHAT's firmware from
the factory default v0.2 to v0.3.

After the FW-upgrade, under Raspbian, it works fine. But under FreeBSD,
it got worse, as now it failed to boot at all. The actual message is:

Net: Net Initialization Skipped
No ethernet found.
libfdt fdt_check_header(): FDT_ERR_BADMAGIC
Hit any key to stop autoboot: 0
U-Boot>

So there is another problem.

Well, thats wrong. In the Banana Pro, we can find (from :
http://www.lemaker.org/product-bananapro-specification.html )

AP6181 Wifi module.

On the RedBear IoT pHAT (from : https://github.com/redbear/IoT_pHAT )=20
there is

AP6212A Wireless with BCM43438 (Wifi + Bluetooth) module.

(the same Broadcom BCM43438 is in the Pi3.)

Thanks,

G=C3=A1bor
