Do_image_teziimg fails

I’m trying to build my custom image for colibri-imx8x, however in the final steps I am getting this error:

ERROR: myos-image-1.0-r0 do_image_teziimg: Error executing a python function in exec_func_python() autogenerated:

I’m using meta-toradex-bsp-common’s dunfell.5.x.y branch.
Looks like the problem is that SPL_BINARY is null.
Any idea how I can fix this?

Bump. Still need help.

Hi @robs !

From this, I understand that the task failing is from a recipe you created, right? If you build a Reference Image from the Toradex BSP (Minimal or Multimedia), does it fail?

From these two lines, seems like the concatenation " " + d.getVar('SPL_BINARY') fails because d.getVar('SPL_BINARY') returned None (which is of type NoneType). Therefore SPL_BINARY seems to be None, which doesn’t feel right.

You can check SPL_BINARY’s value by executing:

bitbake -e myos-image | grep -P '^SPL_BINARY='

Is it possible that your image recipe is somewhat messing with this SPL_BINARY variable?

Best regards,
