I am not able to establish SCCB communication with OV2643 (my 2MP sensor on board). I was not able to use the existing I2C controller to communicate over SCCB. Please note I2C needs an ACK from Slave -- in SCCB there is no ACK concept. Also there is one don't care or NA bit in described in SCCB that is not there in I2C. Hence I wrote my own APB to SCCB controller and started the HW validation. But I am still not getting the correct data from if I read a register over SCCB. Requesting for help -- if there is any know issue etc and how they are resolved. if someone used the I2C to communicate over SCCB, what you did for ACK and Don't care / NA bit. Please give me some information -- I am ok to use i2c or SCCB controller whatever it works. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
