class spsdk.ele.ele_message.EleMessageGetEvents

Bases: EleMessage

Get events request.

Constructor.

This message is used to retrieve any singular event that has occurred since the FW has

started. A singular event occurs when the second word of a response to any request is different from ELE_SUCCESS_IND. That includes commands with failure response as well as commands with successful response containing an indication (i.e. warning response).

The events are stored by the ELE in a fixed sized buffer. When the capacity of the buffer

is exceeded, new occurring events are lost.

The event buffer is systematically returned in full to the requester independently of

the actual numbers of events stored.
