Issue #2899 has been updated by swildner.

I've pushed a commit that hopefully fixes the disk size detection issue you're seeing with mmcsd(4). See the commit msg for further details.


If you need an ISO or IMG with that fix, wait a day or two and it should show up in our snapshots: http://avalon.dragonflybsd.org/snapshots/x86_64/

I haven't done any further testing with it yet.

Please report results. :)

Hi to all DragonFly BSD developers and Community!
Sorry for my bad English...
I am try to install DragonFly BSD to my mini-PC Intel NUC5PPYH CPU Intel N3700, latest at this time BIOS 0050, to SD card Sony 32GB. NUC5PPYH BIOS supports booting Linux/FreeBSD from SD card.
uname -a
DragonFly dfw-7732.localdomain 4.5-DEVELOPMENT DragonFly v4.5.0.763.g541aa16-DEVELOPMENT #0: Tue Mar 29 10:54:30 UTC 2016    root at pkgbox64.dragonflybsd.org:/usr/obj/usr/src/sys/X86_64_GENERIC  x86_64
FreeBSD 10.3 successfully installed and works from SD card, but DragonFly is not. As I am understand, DragonFly detected SD, but Dfly Installer cant support geometry of this mmcsd0.
How I can install DragonFly BSD to SD card?
I am booted from USB stick and can installing Dfly to USB stick or HDD (later, afrer buying new HDD after failed previous), DragonFly Installer: Select a disk on which to install DragonFly BSD.
<da8: 7643MB (15654848 512 byte sectors: 255 63S/T 974C) > # This is bootable USB stick-installer
<mmcsd0> [void space]
If select mmcsd0, then Dfly Installer say about error. As I am understand, Installer cant recognized geometry of SD.
ls /dev/mmc* # on mmcsd0 installed version of FreeBSD 10.3

vendor = 'Intel Corporation'
class = base peripherial
subclass = SD host controller
dmesg | grep sd

sd hci_pci0:1slot(s) allocated
mmc0:<MMC/SD bus> on sdhci_pci0
mmcsd0:29GB < SDHC Memory Card > at mmc0 50Mhz/4bit
On FreeBSD different output data is:
dmesg | grep sd
