Hi Vinoth

probably "GPIO from M4 MCU" means "Rapid General-Purpose Input and Output (RGPIO)"

module of Cortex-M4 Subsystem, however this gpio module has not interrupt feature.

So seems this is not possible.

Best regards

Hi Igor,

I needs to use FLEX CAN (currently flexcan run on M4 Core0) to wakeup the AP.
