hi,

i am trying to change the number of iterations in this coremark wrapper

https://github.com/riscv-boom/riscv-coremark

how come that number of iterations is 40000 and how can i change it.

i tried to change Iterations=10 in MAK file but it didnt change anything.

I don't think that this is a relevant question for the isa-dev or hw-dev lists but, in any case, did you try this?

What about if you pass the number of iterations to the (non bare metal) program at runtime?

unfortunately it didnt work for me. now I'm confuse about the isa simulator, I mean when I change iteration the results should change or I am mistaken.
