Hello All, I have a 8270 based board running Linux 2.6. I am using the i2c available on chip to read / write a i2c mux connected to it. When I open the i2c device, it returns 0 (which shouldnt be) instead of the file descriptor. The /proc/devices shows the i2c driver with major 89 is installed.
10:~# ls -l /dev/i2c-0 lrwxrwxrwx 1 root root 5 Jan 1 02:00 /dev/i2c-0 -> i2c/0 10:~# cat /dev/i2c-0 i2c-dev: i2c-0 reading 4096 bytes. I2C xfer: read from 0xFFFF, flags 0x0001, 4096 bytes I2C error: 0x3C04 cat: /dev/i2c-0: Input/output error Any pointers on what could be wrong ? Regards, Jayaprakash.
