Hi, current code does not support internal sdhc card as root partition? Because kernel does not recognize the sdhc(mmcsd). Do we need external umass storage for root partition? dwcotg0: <DWC OTG 2.0 integrated USB controller> mem 0xf2980000-0xf299ffff irq 17 on simplebus0 usbus0 on dwcotg0 Timecounters tick every 10.000 msec usbus0: 480Mbps High Speed USB v2.0 Root mount waiting for: usbus0 ugen0.1: <DWCOTG> at usbus0 uhub0: <DWCOTG OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0 uhub0: 1 port with 1 removable, self powered Root mount waiting for: usbus0 ugen0.2: <vendor 0x0424> at usbus0 uhub1: <vendor 0x0424 product 0x9512, class 9/0, rev 2.00/2.00, addr 2> on usbus0 uhub1: MTT enabled uhub1: 3 ports with 2 removable, self powered Root mount waiting for: usbus0 ugen0.3: <vendor 0x0424> at usbus0 smsc0: <vendor 0x0424 product 0xec00, rev 2.00/2.00, addr 3> on usbus0 Trying to mount root from ufs:/dev/mmcsd0s2 []... mountroot: waiting for device /dev/mmcsd0s2 ... smsc0: chip 0xec00, rev. 0002 miibus0: <MII bus> on smsc0 ukphy0: <Generic IEEE 802.3u media interface> PHY 1 on miibus0 ukphy0: none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto ue0: <USB Ethernet> on smsc0 ue0: Ethernet address: 9a:ea:92:da:66:31 Mounting from ufs:/dev/mmcsd0s2 failed with error 19.
