How to rewrite RTC registers by ST-link utility, by having .Bin file?

Hi, i've a question. I have a STM32F103VCT6 in the device, i need to rewrite the RTC block, which has the start address is 0x40002800 and has size 0x03FF. I try to rewrite it. But I can't to do it. ST-link utility shows error message: Programing erro...

Proper setting a project with STM32F302VD and STM32F30x_StdPeriph_Driver.

Hi ALL,In file "stm32f30x.h" (and not only in it) exist preprocessor dependent compilation according to symbol defined on project level. There are symbols as STM32F303xC, STM32F302x8 etc., but I can't find something similar to STM32f302VD, STM32f302x...

Is EEPROM Emulation possible with STM32F030F4P6 MCU ?

I wish to read/write data from FLASH Memory (i.e., execute EEPROM Emulation since internal EEPROM is not available).I referred to firmware example code for STM32F030R8, the User_Flash that user can read and write starts from PAGE_16 to PAGE_63 i.e, 1...
