Hello,
I am using Nucleo-F401RE MB1136, want to run the board using the HSE, installed 8Mhz crystal on X3 with 22pf capacitors on C33 & C34 and 0 Ohm resistors on R35 & R37.
Using the CubeMx, configured the HSE pin as Crystal/Ceramic Resonator, set the clock in the Crystal Configuration for HSE as 8Mhz, tried both the ways, directly using HSE as System Clock and with using the PLL block.
Still not able to run the code as the code gets stuck in SystemClock_Config(void), no pulse is generated on the crystal.
Is there any step that i missed or some configuration, please guide me if possible. I am new into the Stm world. Provided the snippet of the CubeMx generated code.
Thank You
