More details

Description
This training is about AUTOSAR Watchdog Stack, design tips and examples.
The training is created by Mohamed El -Nagdi. I have 15 years' experience in embedded systems and mainly in automotive embedded software.
In this course, we will start talking about the need and the meaning of Watchdog Timer, Watchdog types and watchdog in AUTOSAR. As this course focus on Watchdog in AUTOSAR, I will describe the watchdog stack starting with watchdog manager.
What you need to know about Watchdog Manager? The supervisions provided by AUTOSAR in details, such as alive, logical and deadline supervisions, and both state machines in the Watchdog Manager, local and global state machine.
Then we will move to watchdog interface, the overview and main interfaces with watchdog manager, such as setmode() settype() and settriggercondition() functions.
After that we will complete the stack with the watchdog driver, in this part we will explain driver parameters, sync, closed and open window, and how to set safe values with examples.
Moving to watchdog design in different mode, in software reset and in programming session, and how to design the Watchdog in those two modes.
Finally, Watchdog Development Test, how to measure and verify your design, and then we will conclude all of the training. So, I hope to enjoy the training as I enjoyed, prepare it.
