To allocate the particular location to safety variables in the RAM we added new RAM sections in the linker as shown below.we allocated above address to safety variables as shown below from the code.Due to above changes we are getting below warning in...

I am trying to initialize a section of EEPROM address from 0x40A0 to 0x40B8 in STM8AF5288 MCU. Between I am not able to complete this initialization process & end up getting MCU Reset. Attaching the assembly code that does this action BSET _FLASH_CR...

How can we differentiate between Power ON Reset vs MCU Reset initiated by an external watchdog device?I mean is there a Memory Area in STM8AF5288 MCU that retains state after MCU Reset compared to Power ON Reset?I cannot find the source of the MCU Re...

ah ha..!! Nope it isn't a license issue. After keeping the -k option for the RAM sections in linker setting the above error goes away

I did select the MCU STM8AF5288 in STVP while flashing the MCUI need the variables to be located in specific RAM address range that's why defined these sectionsI tried by removing the -k option from settings of compiler but while building the Firmwar...

Thanks for your clarification once again. I did try to run the above assembly program without single step / debug mode and then noticed the changes to the EEPROM write is working as expected.The DUL bit is checked before writing to EEPROM and EOP is ...

Could we use the noinit ram section variables to distinguish between external watchdog applied MCU Reset versus Power ON Reset? Is it possible with STM8AF5288 MCU ?
