[Apache TVM Discuss] [Questions] How to set CPU of Hexagon simulator?

[Iktsuarpokk via Apache TVM Discuss]

I'm trying to do some tests followed [testing 
info](https://github.com/apache/tvm/tree/9273ea5e49ca05404293cb651ced6d0bc0c0f206/tests/python/contrib/test_hexagon).\
I tried to generate a session like this below.\

Then I just try to generate some data and move them to the hexagon simulator, 
just like in the test file.

At this step, I got an error.\
It seems to be caused by copying data to hexagon simulator.\

By checking logfile in the workspace, I found something wierd.\
I build *Hexagon_api* and *tvm* both with `USE_HEXAGON_ARCH=v66`.\
And in my code, I defined target with `target = tvm.target.hexagon('v66', 
link_param=True)`.\
While in the log, it shows that the cpu architecture is not specified.\

So I guess that's the problem.\
After rebuilding *Hexagon_api* and *tvm* with `v68`, everthing turns ok.\
Here it the question, is there a way to set the CPU arch mentioned in the 
figure?\
Is it `v68` by default or is there something wrong with the whole process of my 
code?
