 use SDL V7.9    D:\T2G_Sample_Driver_Library_7.9.0\tviibh8m\src\examples\syspm\DeepSleep\Wakeup_From_GPIO_Interrupt   DEMO, 

  Using the B-H-8M board, it was found during testing that the M0 core could not be awakened by the button, but the M7 core could be awakened. What is the approximate reason for this

EV board is  CYTVII-B-H-8M-176-CPU     ,When I press the SW3 button, it takes 7-8 seconds for the M0 kernel to wake up,    Why does it take so long。

Hi JQ,

for we don't have the 176 pin board on our side, we tested the CYTVII-B-H-8M-320-CPU, followed the description in readme file, both core will wakeup immediately after press the SW1 button. 

please note all cores run into deepsleep mode will consider as deepsleep mode, and must disconnect the debug tools. 

to simple the test, you can dis-enable the CM7_0 and CM7_1, only test the behavior of CM0 to check your issue first.
