AM4376: Error while building the kernel in HS SDK

Part Number: AM4376


We are using AM4376 controller for our development. We are implementing secure boot in the secure controller for that I referred Processor_SDK_Secdev_Build_Install_Guide.pdf 

While building the kernel I referred

and followed the steps mentioned in it. But while building the kernel i am getting below error

Make[1]”*** No rule to make target ‘debian/canonical-certs.pem’ needed by ‘certs/x509_certificate_list. Stop

I referred  the below link

 and tried to modify the same but no success then It gives below error

 Make[1]”*** No rule to make target ‘ ’ needed by ‘certs/x509_certificate_list. Stop

What could be the reason and where to make the change to compile and build the kernel image.

I am using ti-processor-sdk-linux-am437x-hs-evm-
