Hi, Can you try below command in your odroid shell? (Actually, the linux-3.10 is for tizen 3.0.)
$ killall sdbd $ echo 0 > /sys/class/usb_mode/usb0/enable $ echo sdb > /sys/class/usb_mode/usb0/funcs_fconf $ echo 1 > /sys/class/usb_mode/usb0/enable $ sdbd In your host PC, $ sdb devices Best Regards, Chanho Park > -----Original Message----- > From: Dev [mailto:[email protected]] On Behalf Of GyeongHwan > Hong > Sent: Friday, August 29, 2014 11:49 PM > To: [email protected] > Subject: [Dev] SDB does not work on ODROID-U3 > > I am porting Tizen 2.2.1 on ODROID-U3 board, and this work is almost > done. > > > I enabled 'USB debugging' in preferences app and plugged it to Host PC > through USB cable. > > > However, on the host PC(Ubuntu 13.10), 'sdb devices' command does not > show any devices at all. > > Host PC cannot even recognize ODROID-U3 with Tizen as USB storage. > > > When I run Android(a version given by manufacturer) on the same device, > ODROID-U3 is successfully connected to host PC through adb or USB > storage connection. > > > I think that I forgot to port something required for SDB or USB storage > connection. > > > Tizen on ODROID-U3 is using Kernel 3.10, which is based on the Tizen > source code and built by myself. > > I recognized some code related to USB-OTG support in "arch/arm/mach- > exynos/mach-smdk4x12.c"(ODROID-U3 uses Exynos 4412.) and > "drivers/usb/gadget/s3c-hsotg.c". > > SDB-related code is also found in "drivers/usb/gadget/f_sdb.c". > > I guess that this kernel have enough code to support SDB and USB stoage > connection. > > However, I don't know about the full processes of them, so I cannot > ensure it. > > > What components are required for SDB? > > If I know the components, I could resolve this problem. > > Please tell me about it. > > > Thanks, > Gyeonghwan Hong. > > > -- > > Gyeonghwan Hong (RedCarrottt) > Embedded Software Lab. > Sungkyunkwan University > [email protected] _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev
