Because my project can not avoid these things as follows:
My project always go fail into standby and then the API <POWER_SYS_SetMode> returns status.
<Dinit all the peripheral >;
<Set wakeup address and wakeup source >;
stSwitchMode = POWER_SYS_SetMode(standby_mode, POWER_MANAGER_POLICY_AGREEMENT);
if(stSwitchMode == STATUS_SUCCESS)
{
<do something to resume the program>
}
else
{
mcu_reset();
}
However there are two questions.
1. The program has a certain probability to be blocked in there:
2. The program has a certain probability not blocked but all the peripheral do not work。
It is not useful to init again the clock and the powermode.
when <POWER_SYS_SetMode> returns STATUS_SUCCES :
(void)CLOCK_SYS_UpdateConfiguration(0U, CLOCK_MANAGER_POLICY_AGREEMENT);
(void)POWER_SYS_SetMode(drun_mode, POWER_MANAGER_POLICY_AGREEMENT);
<Init all the peripheral >;
But all the peripheral do not work and the mcu can not go into standby.
There are two situation that the program do not block and occur error.
1.
stSwitchMode = POWER_SYS_SetMode(standby_mode, POWER_MANAGER_POLICY_AGREEMENT);
if(stSwitchMode == STATUS_SUCCESS)
{
mcu_reset();
}
else
{
mcu_reset();
}
2.enable the watch dog.
How can i do to resume the program from standby fail to drun and go into standby once again?
