Hi,

I have bread boarded STM32F051 and it's working. The clock is configured for external
8Mhz Crystal. Its working checked with scope. When i remove the crystal it seems to still work from internal oscillator. I would like switchover to be disabled. how can i do it.
using std peripheral lib.
Thanks,
Jai.
