STM32F030RC - I2C2 Not working

OInam
Associate II

Hello,

I am using STM32F030RC and I have connected ST's EEPROM IC M24M01-RMN6P over I2C interface on I2C2.

I have following configuration on STM32CubeMx -

I have selected PA12 -I2C2 SDA and PA11 - I2C2 SCL pin configurations.

I am using 4.7 K resistors as pull-up.

However, I am not able to communicate with EEPROM. I checked on DSO, no waveform is being seen on SDA and SCLK pin.

I have previously used I2C successfully on I2C1.

Is there more configurations required for I2C2?

Where am I going wrong?
