What i understand is that it could help when having problems for a device to lock on cronus mck.
But if everything locks correctly without it, it is not strictly needed (it was not present until newer boards) - anyway if you have J_INV oboard, you have to bridge either MCK+ or MCK-, i think...

I just soldered the J_INV header and put a jumper on MCK+ and it looks like its working now.
Is there a way to know the current firmware on the Amanero? I did flash it to Slave but just want to recheck it as a sanity check.

Previously I did not have a lock on the B3sePro

Good catch - I will add this info to the Cronus overview and the first page.

The jumper allows you to send master clock to Hermes modules either inverted - or non-inverted. In certain (rare) cases sending the master clock inverted can help with phase alignment at the FF. I added the header to give that option. It should work with current Hermes modules with either position jumped.

Cheers!
Russ
