sabrelite I2c

Former Member
Former Member over 12 years ago

Hi,

I am configuring i2c3.I am using GPIO5, and GPIO16 for SCL and SDA.

I am using default settings in all other registers except I am configuring these registers

 

IOMUXC_SW_MUX_CTL_PAD_EIM_DATA17

IOMUXC_SW_MUX_CTL_PAD_EIM_DATA18

IOMUXC_SW_PAD_CTL_PAD_EIM_DATA17

IOMUXC_SW_PAD_CTL_PAD_EIM_DATA18

IOMUXC_I2C3_SCL_IN_SELECT_INPUT

IOMUXC_I2C3_SDA_IN_SELECT_INPUT

 

and Iam enabling clock from CCGR2[10,11] and then using all registers of I2c controller adr,ifdr,i2sr,i2cr,i2cdr

I am not getting any data on my pins always zero.....

Can you please guide me ,Is there any other configuration needed? OR on what side the problem may be?

Also, is there any place where Linux BSP or source code of i2c  are available

Thanks in advance

    If you can, use the in-kernel driver. If not then at least you have a starting point that you know should be working.
