Hi
I am using an AMCC 440EPx processor on "Sequoia" board with Linux 2.6.21rc4. I
am trying to use the i2c in the user-space
In my Linux config file (Sequoia default) i have:
CONFIG_I2C=y
CONFIG_I2C_CHARDEV=y
I than added the "i2c-0" device in /dev (# mknod i2c-0 c 89 0)
When I run a simple program to open the device (provided by the
"dev-interface" file of i2c kernel documentation) it returns errno
message: "No such device".
I have tried to use the device number 1, 2, 3, 4 but with no luck.
Any suggestions what I might be doing wrong?
Best Regards
Marko
