Hi j-breeze,
NotifyDriverCirc_numMsgs is specific to the NotifyDriverCirc module. It determines how many slots there are in the circular buffer, hence determines the size of the it.
Notify_numEvents is a different quantity and determines how many events are supported by Notify in general. It is not used in computing the circular buffer size, if that is your concern.
To configure NotifyDriverCirc_numMsgs, you would need to add the following lines to your BIOS configuration (.cfg) file:
NotifyDriverCirc = xdc.useModule('ti.sdo.ipc.notifyDrivers.NotifyDriverCirc');
NotifyDriverCirc.numMsgs = 32; /* Set it to the number you want */
Best regards,
Vincent
