We need set i.mx6's i2c to slave mode.But not occur interrupt.
The following is my initialization step:
writeb(0x20, i2c_imx->base + IMX_I2C_IADR);//set i2c slave addr to 0x20
writeb(I2CR_IEN, i2c_imx->base + IMX_I2C_I2CR);//enable i2c
temp = readb(i2c_imx->base + IMX_I2C_I2CR);//
temp |= I2CR_IIEN;
writeb(temp, i2c_imx->base + IMX_I2C_I2CR);//enable i2c interrupt
Then other device i2c send to mx6, and i.mx6 not occur interrupt.
Who knows what's the problem?
