maybe this question is very basic, but unfortunately I was not able to find a solution, neither in this forum, nor elsewhere.
My goal is: to let the I2C working on the EVK and on our custom board with iMX23.
I have configured ltib in such a way to support I2C as master.
After correctly booting from SD:
1) modprobe i2c-dev:
>>>>> i2c /dev entries driver
2) echo "a" > /dev/i2c-0
and all that i get is that the SCK line toggles correctly while the SDA still remain pulled up to VDDIO.
The same behaviour appear also if i run this simple program:
fds = open("/dev/i2c-0", O_RDWR);
buf = 0xAA; buf = 0xBB;
Could anyone can help me to understand what I miss to do or to find an error?
Thanks in advance,
