Here is the version running from SD card:
# dmesg | grep isp
[ 0.265502] omap-iommu omap-iommu.0: isp registered
[ 2.986541] omap3isp omap3isp: Revision 2.0 found
[ 2.991577] omap-iommu omap-iommu.0: isp: version 1.1
[ 2.997406] omap3isp omap3isp: hist: DMA channel = 0
[ 3.006256] omap3isp omap3isp: isp_set_xclk(): cam_xclka set to
21600000 Hz
[ 3.011932] omap3isp omap3isp: isp_set_xclk(): cam_xclka set to 0 Hz
From NAND using UBIFS:
# dmesg | grep isp
[ 3.457061] omap3isp omap3isp: Revision 2.0 found
[ 3.462036] omap-iommu omap-iommu.0: isp: version 1.1
[ 3.467620] omap3isp omap3isp: hist: DMA channel = 0
[ 3.472564] omap3isp omap3isp: isp_set_xclk(): cam_xclka set to
21600000 Hz
[ 3.478027] omap3isp omap3isp: isp_set_xclk(): cam_xclka set to 0 Hz
Seems to be missing:
omap-iommu omap-iommu.0: isp registered
Is that the issue? Why would this not work when running from NAND?
Cheers,
Chris
