analogRead() Freezes the program

The Code:

Im using STM32Duino Core, Arduino-CLI with VSCode Arduino Extension

When the code reaches analogRead() function it just freezes the Chip

Please let me know what could be the issue?

also the baud generated by the MCU is 8 times less than real baud, MCU Clock is working fine but i have to multiply baud by 8 to get correct Serial Baud Rate

i.e : Serial.begin(9600) works with Baud1200 in proteus
and Serial.begin(9600 * 8) works with baud 9600 in proteus

You probably have to redefine HSE_VALUE if you use it.
This would explain issue with baudrate.

I tried this but still didnt work
I tried setting HSE_VALUE to 16m and 8m to see if baudrate changes but no, same with HSI_VALUE

just Checked interrupts dont work either .-.

With code: attachInterrupt(digitalPinToInterrupt(PA0), update, CHANGE);
and update function with Serial.println("Tick"); but no response from interrupt, i tried using direct pin name instead of digitalPinToInterrupt() and didnt work either.

Which mcu you used and target you select?

Which mcu you used and target you select?

I'm using STM32F401VE MCU in Proteus

and STM32F401VETx Generic in Arduino IDE

Have you checked if board setup in stm32duino (clocks, etc) is same are your hardware ??

Proteus only has External Clock Frequency for STM which is set to 8Mhz by default

Idk about board setup, please let me know what files have configs

Generic uses HSI. So not an HSE issue.
