Hi Laurent, With 3.2-rc2, omap3isp seems to silently hang in my setup (sensor-less OMAP3).
Turning on lockdep yields the below messages, care to take a quick look ? Thanks! Ohad. root@zoom3:~# media-ctl -r -l '"OMAP3 ISP CCP2 input":0->"OMAP3 ISP CCP2":0[1], "OMAP3 ISP CCP 2":1->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]' media-ctl -f '"OMAP3 ISP CCP2":0[SGRBG10 1280x1024], "OMAP3 ISP CCP2":1[SGRBG10 1280x1024], "OMAP3 ISP CCDC":1[SGRBG10 1280x1024], "OMAP3 ISP CCDC":2[SGRBG10 12 80x1023]' [ 29.014221] Linux video capture interface: v2.00 [ 29.423675] omap3isp omap3isp: Revision 15.0 found [ 29.429168] omap-iommu omap-iommu.0: isp: version 1.1 Resetting all links to inactive Setting up link 2:0 -> 1:0 [1] Setting up link 1:1 -> 5:0 [1] Setting up link 5:1 -> 6:0 [1] Setting up format SGRBG10 1280x1024 on pad OMAP3 ISP CCP2/0 Format set: SGRBG10 1280x1024 Setting up format SGRBG10 1280x1024 on pad OMAP3 ISP CCP2/1 Format set: SGRBG10 1280x1024 Setting up format SGRBG10 1280x1024 on pad OMAP3 ISP CCDC/0 Format set: SGRBG10 1280x1024 Setting up format SGRBG10 1280x1024 on pad OMAP3 ISP CCDC/1 Format set: SGRBG10 1280x1024 Setting up format SGRBG10 1280x1023 on pad OMAP3 ISP CCDC/2 Format set: SGRBG10 1280x1023 Setting up format SGRBG10 1280x1023 on pad OMAP3 ISP AEWB/0 Unable to set format: Invalid argument (-22) Setting up format SGRBG10 1280x1023 on pad OMAP3 ISP AF/0 Unable to set format: Invalid argument (-22) Setting up format SGRBG10 1280x1023 on pad OMAP3 ISP histogram/0 Unable to set format: Invalid argument (-22) At this point, running 'yavta.sh CCP2 input' and 'yavta.sh CCDC output' in two different terminals yields: root@zoom2:~# [ 55.867156] INFO: trying to register non-static key.
