Others: STM32 MCUs related

I had interface EEPROM with STM32G4 board and I have to flash a project code in EEPROM as my Flash memory of the board is not sufficient for my project(code size is large).So is it possible to flash my code inEEPROM and execution of code store in EEPROM?.

Does ST provide an example code driver for connecting its STM32L4xx MCU with its I2C EEprom M24C32-F?

stm32l476rg flash read-write

I want to use flash as eeprom by using hal library on stm32l476rg.How can I create the flash_read() and flash_write() functions? (functions will read and write data of type uint32_t)

Retarget printf for iar

Keil Trace Exceptions

As shown below the screen, when I am running the MCU application, it is running without any flaws. However, when I notice the TraceExceptions window on Keil IDE, noticed a large number of hard faults occurring. But these faults do not trigger fault h...
