Code generated for I2C communication using cubeMX & true studio is not working

[YS]

I am using STMCubeMx V5.2.1& Atollic True studio V9.2 for generating code using HAL libraries/functions . The MCU is STM32F103C8T6(Blue pill board).

I am trying to write & read the one byte data from eeprom AT24CM02 using I2C communication

I used PB6 & PB7 pins in the board for I2C.

& st-link to program the board

Slave address = 0xA0 for AT24CM02

I used HAL_I2C_mem write/read function.

Observations: Using an oscilloscope, i can see that there is no clock signal on SCL pin. The voltage at the SCL pin is always low. The voltage on the SDA pin is always High.

But with same board and same hardware connection it is working with Arduino IDE & i can see the clock signal in oscilloscope.

I am not able understand what is the exact problem with software generated by Cube Mx .

because of this issue my project is not moving forward, so any one can help me to solve this issue it will be great help.

Below I have copied the code from main() function:

HAL_GPIO_TogglePin(GPIOC,GPIO_PIN_13);

 else

 HAL_GPIO_WritePin(GPIOC,GPIO_PIN_13,GPIO_PIN_RESET);

 HAL_Delay(500);

 }

 /* USER CODE END 3 */

}
