I used the nucleo-h401re (rev C01) with x-nucleo-ihm08m1，and I use Motor Profiler 5.Y.2 to measure my motor。it doesn't work

[zHua.1]

It tells serial doesn't work well,and I test it throght my serial application,it works!So who can tell me what's the matter?I found my nucleo-f401(rev C01) don't have external crystal oscillator,and the rev-C04 and rev-C04 all have a external crystal oscillator,So I want to know This software(MCSDK Motor Profiler 5.Y.2) download the binary used external crystal oscillato?

Hello @zHua.1​ , 

We will soon modify the connection procedure to remove this kind of problem.

A fix should come in the next version of the MCSDK.
