Hello,
I need to pass a variable from the CM7 to the CM4.
I used the excellent exemple from "jerteach" on this forum
: my-examples-for-the-arduino-portentaH7/my02c-dual-core-RPC-variable.ino at master · hpssjellis/my-examples-for-the-arduino-portentaH7 · GitHub
Except I'm reversing the flow of data ( CM7 to CM4 instead of CM4 to CM7 in the exemple.
The code compile and works. but stopped (Portanta blink red and I need to reset it) after a certain number of "Call" function as been initiated.
I am sure it comes from the Call function and is relative to the number of time (1560) it is initiated, as if I add a delay, it will take longer before the Portanta freeze, and If I remove the Call function, everything works fine.
The thing is I don't exactly understand how the RPC is working and what could cause that. Any ideas ?
Thanks.
