Hi,

If I configure the LSI as clock source my STM32C011F4U6TR code stuck at this point

However there is no problem if I configure HSISYS as clock source.

Why? Could anyone help me with this issue?

Thanks in advance,
Gaston

    With a 32 kHz clock rate, you don't have enough CPU resources to handle sys ticks occurring at 1 kHz. Increase clock speed, decrease the rate of systicks, or disable sys tick entirely, or rewrite systick not to use any cpu resources.
