Compilation error when using Hexagon

Questions
#1

I followed the instruction and set

USE_LLVM ON
USE_HEXAGON ON
USE_HEXAGON_SDK <SDK 3.5.2 dir>
USE_HEXAGON_RPC ON

and the error occurs during compilation

Does TVM only support V67 ISC?

#2

No, TVM supports v65-v69, but it requires SDK 4.0.0 or later.

#3

Thanks for the quick rely! Let me try latest SDK.

#4

After upgrading to 4.1.2 SDK, the compilation error was resolved.
