Do you have the actual build log for this? On x86 the build process builds any precursors first, which is the tpm2key.asn1.o, which generates that header file, so we see: ASN.1 security/keys/trusted-keys/tpm2key.asn1.[ch] CC [M] security/keys/trusted-keys/trusted_tpm2.o CC [M] security/keys/trusted-keys/tpm2-policy.o CC [M] security/keys/trusted-keys/tpm2key.asn1.o LD [M] security/keys/trusted-keys/trusted.o Is ARM doing a lazier version of that? In which case the fix might be to move trusted_tpm2.o to after tpm2key.asn1.o in the Makefile, this line: trusted-y += trusted_tpm2.o tpm2key.asn1.o James
