const unsigned char __tvm_dev_mblob[46788038] = {“TVM_BLOB_SIG”}; maybe not enough. because 46788038 is too big for many embedded system, so I have to place __tvm_dev_mblob to special section, for example, a rodata section. so I mean I need declare __tvm_dev_mblob as const unsigned char __tvm_dev_mblob[46788038] attribute((section(".rodata"))); the declaration grammar is compiler specific, put to which section is compiler specific too. so I think the RFC need to consider the case.
