Arduino for STM32

Hum, you told you used external EEPROM ? but your code is for EEPROM emulation.
This explain your issue as for STM32F401CC:
Sector 7 0x0806 0000 - 0x0807 FFFF 128 Kbytes

So with EEPROM emulation the last sector is used but your program goes into this sector.
Simply try to remove the EEPROM ...

Hi,
I don't think it is linked to flash size but to other reason.
But hard to tell which one without the code. Some input: RAM usage? IRQ? interrupt handler management?


Hi fpiSTM,
Thanks for replying. My RAM usage is %40 (26512), as for the IRQ I never disabled or enabled it in my code.
I am ...

Hello, A year ago I made a controller with Arduino Mega but recently I learned there was no good trusting in arduino so I bought STM32F411C(512kb Blackpill) and STM32F401CC(256kb Blackpill). I have been coding and implementing for STM32F411(512kb) using Arduino IDE(I compile the code and upload as ...
