Dear All,
I'm devepoling an application using an STR711FR2 and EMBOS Operating System with Keil uVision3 IDE.
In my application I have an interrupt coming from the RTC at 32Hz. The MCU have to do some operations than it should go in LPWFI using the RTC as clock source.
I disable all the PLLs and then call the function
PCU_LPModesConfig(DISABLE, DISABLE, DISABLE, ENABLE, LPWFI_CK_AF);
from the STR7 library and then WFI.
The device seems to work and the power consumption drops down. The problem is that after some minutes something goes wrong and the application stops.
If i don't put the flash in power down the application seems to work.
I've read that i should not use the flash in the first 20us after power on, my application is actually mapped in ROM, should I remap the interrupt service routine to RAM? In this case which is the procedure?
thank you for your help
