I2C iMX6DL

[djillaliredjrad]

Hi,

I'm trying to use an I2C gyroscope (L3G4200D) on Karo TX6DL (iMX6DL),  I think that the bit start is generated because the IBB bit toggle from 0 to 1, but I don't receive an acknowledge from the slave, when I control scl pin with oscilloscope, I don't find a clock signal.

Where is the problem ?

Hi Djillali

it may be recommended to check if SION bit is set in i2c

iomux registers IOMUXC_SW_MUX_CTL_PAD_KEY_X.

Also please check if clock is enabled in CCM_CCGR register.

Best regards

igor
