I have a custom board running with ChibiOS with a simple "Hello world" thread which blinks a led. This program works fine when I use the intern oscillator of the microprocessor, but for some reason I can't make it work with an external clock (which I need for another use of my board).
Indeed, in this case the led doesn't blink anymore, proving that the entire board is stuck.
Here are the relevant parts of my configuration files :
In mcuconf.h :

#define STM32_LSEDRV (3U << 3U)
#if !defined(STM32_HSECLK)
#define STM32_HSECLK 25000000U
#endif
#define STM32_HSE_BYPASS
Does anyone has an idea on how I could make my board work with the external clock ?
I use Chibios stable 18.2 and my platform is STM32L496
Any kind of help would be very much appreciated !
