Hello, I'm trying to use stop mode on my MCBSTM32E eval board (MCU STM32F103ZE). I've found examples in Keil installation folders. It seems to work til I enable the Systick timer. Indeed, in this case the stop mode is ignored and the systick interrupt happens as usual without any effect. In the example, the Systick is disabled before entering stop mode and re-enable after. Why do we need to do so because in the Reference Manual (RM0008) page 52 (table10) it is said that the instruction is ignored if flags are not reset, but it is not the case here. I thought that by activating stop mode it would stop clocks and so the systick timer. Does anyone have this kind of trouble ? Thanks in advance.
I have a similar problem with STR750. If I enter stop mode while debugging with ULINK2, it refuses to communicate. Strangely thou, ULINK does work.
Best regards
