Hi @TDK ,Thanks for suggestion.To recover from a situation in which SDA is stuck low:Deinitialize the I2C peripheral.Re-initialize the SDA pin as a GPIO open-drain output.Send 9 negative-going pulses on this line with a frequency of 100 kHz or less.R...

@TDK ,@I didn't changed anything in the flash programing.where do I need to check this correct vector address of my mcu is it it datasheet? and where do I need to set this vector address is it is the flash.c ?? Thanks
