AM4376: Error while building the kernel in HS SDK

Hi,

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  https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components_Kernel_Users_Guide.html

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 

https://stackoverflow.com/questions/67530734/no-rule-to-make-target-when-compiling-linux-kernel-when-needed-by-certs-x509-cer

 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-06.03.00.106-Linux-x86-Install.bin
