I am trying to follow this document Generate Blob Under Linux for generating blob for our custom board based which used imx6ul processor. But when I try to load generated key_blob_module.ko I get following error
insmod key_blob_module.ko

insmod: ERROR: could not insert module key_blob_module.ko: Unknown symbol in module
How can I resolve my problem?
