Recurces distribution between M4 and M7

Official Hardware Portenta Family Portenta H7

Hi,
after the fist try with Portenta H7 seems that the serial is accessible only from the M7 side. Eg:

Serial.begin(115200);
Serial.print("M4 ");

has no effect on M4 core. Where can i found a table or so to understand which function/resource is available to which side?
Thank you

Hi @mlucarelli This link is for the GIGA but applies equally to the Portenta H7

Nice, thanks
Basically: pin priority is random; Serial and Wifi are accessible only from M7.
