mxc_v4l2_capture on imx6q

[shlomiperlman]

Hi,

when loading the mxc_v4l2_capture.ko module with insmod im getting these errors:

   mxc_v4l2_capture: Unknown symbol v4l2_int_ioctl_0 (err 0)
  mxc_v4l2_capture: Unknown symbol v4l2_int_ioctl_1 (err 0)
  mxc_v4l2_capture: Unknown symbol csi_enc_deselect (err 0)
  mxc_v4l2_capture: Unknown symbol bg_overlay_sdc_select (err 0)
  mxc_v4l2_capture: Unknown symbol bg_overlay_sdc_deselect (err 0)

I even tried modifying the source but the error for v4l2_int_ioctl_0 and v4l2_int_ioctl_1 persists!

when using modprobe it tries to load ipu_fq_overlay_sdc.ko first and says: invalis module format...?

as a result i cant use my camera driver.

what do i do?

Hi,

the Yocto Project build doesn’t deem to have support for the BDSL-SabreLite Board.

can one of the build option make a kernel that will run on this board?
