Hi!

Hmm, and with similar config, I got N950 to work. ... which should
give me enough clues to get N9 to work. I guess I forgot to reset the
pipeline between the tries, or something.

For the record, this got me some data on n950:

 m.media_ctl( [ '-f', '"OMAP3 ISP CSI2a":0 [fmt:%s/%dx%d]' % (m.fmt, m.cap_=
x, m.cap_y) ] )
 m.media_ctl( [ '-l', '"OMAP3 ISP CSI2a":1 -> "OMAP3 ISP CSI2a output":0[1]=
' ] )

 # WORKS!!!!
 # pavel@n900:~/g/tui/camera$ sudo /my/tui/yavta/yavta
 # --capture=3D8 --skip 0 --format SGRBG10 --size 4272x3016 /dev/video1 --f=
ile=3D/tmp/delme#

=2E..ouch. It only worked twice :-(. Either driver gets confused by my
attempts, or it relied on some other initialization code. Strange.

Best regards,
									Pavel
