-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The board is FriendlyArm tiny4412 ver.1306. I have made the mmc2(sd slot) work and place rootfs in it. But I failed in usbhost part(not otg which has been broken by me), which works properly in manufacturer's kernel. I can't find the ehci controller and root hub at all. In this board, the usb host is conntected to a external hub to change voltage level. in dmesg, log shows as below: [ 1.075000] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 1.075000] ehci-exynos: EHCI EXYNOS driver [ 1.075000] unable to find transceiver of type USB2 PHY [ 1.075000] exynos-ehci 12580000.ehci: no platform data or transceiver defined [ 1.085000] platform 12580000.ehci: Driver exynos-ehci requests probe deferral -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJSjwn3AAoJEPb4VsMIzTziaFIH/0wxwYrSp0HCSQtCN8v4g9Vj 2YxATdQ/SeTLN6F+h6ggooIlaWOUyH2H+yz73T4YYnh+swqPUGyBoXa6KZNep2na O9xCNWSntELXHKJqrVFPBOBSWkhqf71q4DbApWHZYMvVCa1UhAYqg6AFy5M3gMWl jbMd5SBDwKjIioJhgOgqGa1w2HUp8QNmCACtKl+YagTBNAdv3BJr7egKhWoRqOQR INk2kb3UeptmKeTL08uUcgxMxEAn/W+r53FBjbvuU+TKMccj48kpWpZ513hfKKva W9NmaLWDiuV73kz135o/955lCO7wdrs2cVtp37g6BCc0U+RdUI3tqwyswYFWwg4= =suW2 -----END PGP SIGNATURE-----
