hi
i am having trouble in getting lm_sensor 2.7.0 working on tyan s2720 board with
linux kernel 2.4.19.
The s2720 onboard hardware monitoring devices include Winbond W83627HF,
Winbond W83782d and two 'on Chip Xeon Thermal Sensor' at address 0x18 and 0x19.
the i2c-detect script suggest to load the following modules i2c-isa, i2c-i801, w83781d
and eeprom. After loading the suggested modules on running the i2cdetect gives the
following output
Installed I2C busses:
i2c-0 smbus SMBus I801 adapter at ec80 Non-I2C SMBus adapter
i2c-1 dummy ISA main adapter ISA bus algorithm
in the lm_sensor mailing list, found an advice to load the adm1021 module to get the
temperature from xeon processor. loaded the adm1021 module on bus 0,0x18.
running the sensors gives wrong temperature(-1) for adm1021. tried loading the module
in both address 0x18 and 0x19.
one think i noticed is when i load the i2c-velleman (this module is loaded when during
the sensors-detect script, though the script doesnt suggest to load this module) the i2cdetect
shows up the following result.
again loading the adm1021 on the i2c bus 2 results the same output(-1).
Installed I2C busses:
i2c-0 smbus SMBus I801 adapter at ec80 Non-I2C SMBus adapter
i2c-1 dummy ISA main adapter ISA bus algorithm
i2c-2 i2c Velleman K8000 Bit-shift algorithm
any information is appreciated.
