omap_musb_mailbox: musb core is not yet ready message. It looks related...?Can you try tree https://gitorious.org/linux-n900/linux-n900/ ? I think with rx51_defconfig from above tree it worked fine for 3.10 - 3.13 versions.From your tree, I am trying 815039686baffff6432b45028dd405b1981a9112 (3.16 based). I attempted to make gadget drivers build-in and enabled nfsroot. I could not detect nokia on USB after bootup. Are you sure about defconfig? AFAICT defconfig will always be unsuitable for nfsroot, as it will not contain nfs support built-in... I am trying c089e5f8ba2d44afd2db2c2042d43ca70205c536 (3.13 based). Same result :-(. Do you have any tree where usb gadget works for you?My N900 can boot kernel from v3.12-rc5-n900 branch compiled with arch/arm/configs/rx51_defconfig. Also it can boot full Maemo5 system (with CSSU and some minor system changes) and usb network via g_nokia.ko gadget working fine...
Thanks for the info. Network seems to work on this one.
So if it does not working for you then kernel usb subsystem could have problems with using gadgets directly from zimage.
It seems to work with 3.12, but not with 3.13 (in similar config). If you could test USB networking in 3.13, that would help... Thanks, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
