Hi,

 

I have a strange behavior, my program is working well when i use it as normal.

When i use bootloader and put my program with an offset in flash, the __WFI make nothing !

All is correct, i checked PCON & SCR but when __WFI is executed the processor don't enter in sleep mode.

My debug probe doesn't disconnect, current stay in full range and my program goes on ...

 

Is someone have hints ?

Because i don't understand and don't know where search for correct this.

 

Thanks a lot, Philippe.

 

PS : The bootloader is used for firmware flash from USB Key and is working (many used before this try)

Sorry for my english.
