Please check https://bugzilla.kernel.org/show_bug.cgi?id=85201 I aim to use a Cinergy HTC USB XS on ARM with xbmc. The USB stick uses a the driver dvb-usb-dib0700 with the firmware dvb-usb-terratec-htc-stick-drxk.fw taken here wgethttps://github.com/OpenELEC/dvb-firmware/blob/master/firmware/dvb-usb-terratec-htc-stick-drxk.fw I checked on a amd64 PC and successfully media_builded, installed VDR and scan utilities and scanned TV channels with w_scan -ft-A3-c FR >/etc/vdr/channels.conf So I switched to the ARM real target. I encountered this error while executing './build' in build_media directory : CC [M] /root/media_build/v4l/mcam-core.o CC [M] /root/media_build/v4l/coda-common.o /root/media_build/v4l/coda-common.c: In function 'coda_probe': /root/media_build/v4l/coda-common.c:1893:2: error: implicit declaration of function 'devm_reset_control_get_optional' [-Werror=implicit-function-declaration] /root/media_build/v4l/coda-common.c:1893:12: warning: assignment makes pointer from integer without a cast [enabled by default] cc1: some warnings being treated as errors make[3]: *** [/root/media_build/v4l/coda-common.o] Error 1 make[2]: *** [_module_/root/media_build/v4l] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-3.14.14+' make[1]: *** [default] Error 2 make[1]: Leaving directory `/root/media_build/v4l' make: *** [all] Error 2 build failed at ./build line 491. Here is the context The device is a CuBox-i4Pro (SoC is i.MX6 Quad see here :http://www.solid-run.com/wiki/CuBox-i_Hardware) I use the Debian wheezy available at the link given herehttp://www.solid-run.com/wiki/Debian_and_derivatives and more specificallyhttp://www.igorpecovnik.com/2014/08/19/cubox-i-hummingboard-debian-sd-image/ I build a kernel 3.14 as said herehttp://www.solid-run.com/wiki/Building_the_kernel_and_u-boot_for_the_CuBox-i_and_the_HummingBoard and generated kernel packages with apt-get install dpkg-dev apt-get install libfile-fcntllock-perl make deb-pkg cd .. dpkg -i linux*deb And then git clone git://linuxtv.org/media_build.git cd media_build ./build And that's where the error occurs I can't go farther.
