On our board (pdnb3 from prodrive) we have use software support for gpio. Look into this board configure to figure out how to support this.
I got the I2C working on some level. I configured the I2C-commands so I could test the I2C from command line.
Iprobe - gets the addresses pretty much what it supposed to be, but the problem is the reading with imd -command. Some times the command seems to be working almost fine. Some times the results are difrerent every time I read the chip when it should be the same since I'm trying to read a chip that has constant data(for example eeprom). Most of the time not all the data is read. Maybe first 3-4 bytes are ok and rest of the bytes are either 00 or ff.
Should I somehow reset the I2C-bus, am I doing something wrong or maybe there is some configuration error or maybe even a bug in a code?!
I tried to slow down the speed to 40kHz, but no help. The CPU should be running at 530MHz, so it should be able to work with the 40kHz bus speed.
Thanks.
