I'm trying to implement l3dd20h gyro. I'm using stm32f4 discovery board.When
I look i2c2 SCL and SDA lines with logic analyzer, I only see clock is
working as expected but here is no data at SDA pin. Here is my configuration

my altimu10 makefile:  imu_altimu10.makefile

I'm just using i2c_submit fuction to read WHO_AM_I register of the chip. 

If you can assist me, I'll be very glad.

Thanks for help!
