Just change your argument -DUSE_HEXAGON_ARCH=v65 to v68 or after, cause hexagon don't support v65 func

[chayliu-ecarx]

I met the same problem for v66 while using Hexagon_SDK_4_5.

error such as :
hexagon_user_dma_instructions.h:29:16: error: invalid instruction
asm volatile(" %0 = dmpause" : "=r"(dm0));
