hi I am grateful for the help that will be given to me. Please help me with the launch of the cam500a by Nano Air. I tried to use http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Air#Connect_to_DVP_Camera_CAM500B guides and go along with it.  but I did not succeed . I am very beginner and need help.  This is all that I get by following the guide http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Air#Connect_to_DVP_Camera_CAM500B. What should i do

I also feel there is another problem, I do not understand it When I execute command ''make'' , the operation is not successful Can you guide me where the problem is? root@NanoPi-NEO-Air:~/mjpg-streamer# make make: svnversion: Command not found make: Warning: File 'Makefile' has modification time 427105 s in the future gcc -D'SVN_REV=""' -O2 -DLINUX -D_GNU_SOURCE -Wall -c -o mjpg_streamer.o mjpg_streamer.c gcc -D'SVN_REV=""' -O2 -DLINUX -D_GNU_SOURCE -Wall -c -o utils.o utils.c gcc -D'SVN_REV=""' -O2 -DLINUX -D_GNU_SOURCE -Wall mjpg_streamer.o utils.o -lpthread -ldl -o mjpg_streamer chmod 755 mjpg_streamer make -C plugins/input_uvc all make[1]: Entering directory '/root/mjpg-streamer/plugins/input_uvc' make[1]: Warning: File 'Makefile' has modification time 427103 s in the future gcc -c -O1 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC -o v4l2uvc.lo v4l2uvc.c v4l2uvc.c: In function ‘init_videoIn’: v4l2uvc.c:88:23: warning: variable ‘currentHeight’ set but not used [-Wunused-but-set-variable] int currentWidth, currentHeight = 0; ^ v4l2uvc.c:88:9: warning: variable ‘currentWidth’ set but not used [-Wunused-but-set-variable] int currentWidth, currentHeight = 0; ^ gcc -c -O1 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC -o jpeg_utils.lo jpeg_utils.c jpeg_utils.c: In function ‘compress_yuv_to_jpeg’: jpeg_utils.c:208:27: warning: ‘v’ may be used uninitialized in this function [-Wmaybe-uninitialized] r = (y + (359 * v)) >> 8; ^ jpeg_utils.c:209:26: warning: ‘u’ may be used uninitialized in this function [-Wmaybe-uninitialized] g = (y - (88 * u) - (183 * v)) >> 8; ^ jpeg_utils.c:209:20: warning: ‘y’ may be used uninitialized in this function [-Wmaybe-uninitialized] g = (y - (88 * u) - (183 * v)) >> 8; ^ gcc -c -O1 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC -o dynctrl.lo dynctrl.c gcc -O1 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC -o input_uvc.so input_uvc.c v4l2uvc.lo jpeg_utils.lo dynctrl.lo -ljpeg make[1]: warning: Clock skew detected.

Is cam500a the only problem? Is the problem resolved by changing it to cam500b? There is no way to answer the cam500a? Thank you very much for your directions
