My company is starting to implement an auto provisioning mechanism for
web servers, I want to keep track of memory serial numbers by the data
in the SPD EEPROM on the sdram. I can access this fairly easily from
i2cdump. However, our kernels do not support module loading (for
security) and I have to compile all the drivers into the kernel. sensors
exec shows the i2c bus and sensor information from it but i2cdetect
returns :
Error: No i2c-bus specified!
Syntax: i2cdetect [-y] [-a] [-q|-r] I2CBUS [FIRST LAST]
i2cdetect -l
i2cdetect -V
I2CBUS is an integer
With -a, probe all addresses (NOT RECOMMENDED)
With -q, uses only quick write commands for probing (NOT RECOMMENDED)
With -r, uses only read byte commands for probing (NOT RECOMMENDED)
If provided, FIRST and LAST limit the probing range.
With -l, lists installed busses only
Error: No I2C busses found!
Be sure you have done 'modprobe i2c-dev'
and also modprobed your i2c bus drivers
This is on debian with a vanilla kernal recompiled for i2c support. Are
my i2c tools out of date?
