I am trying to setup the device tree to enable a parallel camera interface as found on the LPD Dev Kit. The instructions I am using for the basis are: https://alaganraj.wordpress.com/2015/08/08/beagleboard-xm-camera-li-5m03-mt9p031-support-with-device-tree/ It I get the same results when I compile it into the kernel or as a module, but the errors are the same. When I modprobe it, I get: # modprobe omap3-isp omap3isp 480bc000.isp: parsing endpoint /ocp/isp@480bc000/ports/port@0/endpoint, interface 0 omap3isp 480bc000.isp: Revision 15.0 found iommu: Adding device 480bc000.isp to group 0 omap-iommu 480bd400.mmu: 480bd400.mmu: version 1.1 omap3isp 480bc000.isp: hist: using DMA channel dma0chan6 omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP CCP2 was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP CSI2a was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP CCDC was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP preview was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP resizer was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP AEWB was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP AF was not initialized! omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP histogram was not initialized! # I then modprobe the mt9p031 driver, and it won't initialize, but it is detected. # modprobe mt9p031 [ 127.390808] 1-0048 supply vdd not found, using dummy regulator [ 127.398101] 1-0048 supply vaa not found, using dummy regulator [ 127.404907] omap3isp 480bc000.isp: isp_xclk_set_rate: cam_xclka set to 21600000 Hz (div 8) [ 127.432861] mt9p031 1-0048: MT9P031 detected at address 0x48 [ 127.438873] omap3isp 480bc000.isp: Entity type for entity mt9p031 1-0048 was not initialized! # I can post my device tree if necessary, but it's basically like what's in the link above. Does anyone have any ideas on what I am doing wrong? adam -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
