Hallo,
ich versuche gerade, einen an den i2c Bus gehangenen LM75 mit sensors auszulesen. Leider wird der LM75 nur mit sensors-detect erkannt, ist aber irgendwie nicht über sensors ansprechbar. Kann sich vielleicht ein Spezi meine output's ansehen und mir einen Tip geben ?
Bei mir läuft im Moment noch MVDR1.3, aber auch unter suse9.2 bekomme ich es nicht hin...
Vielen Dank im Voraus
linux:~ # sensors-detect
This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.
It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.
We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no): y
Probing for PCI bus adapters...
Use driver `i2c-matroxfb' for device 01:00.0: MGA G200 AGP
Use driver `i2c-piix4' for device 00:07.3: Intel 82371AB PIIX4 ACPI
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Load `i2c-matroxfb' (say NO if built into your kernel)? (YES/no): n
Module `i2c-piix4' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.
We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).
Next adapter: SMBus PIIX4 adapter at f0b0 (Algorithm unavailable)
Do you want to scan it? (YES/no/selectively): y
Client found at address 0x49
Probing for `National Semiconductor LM75'... Success!
(confidence 6, driver `lm75')
Probing for `Dallas Semiconductor DS1621'... Failed!
Probing for `National Semiconductor LM92'... Failed!
Probing for `National Semiconductor LM76'... Failed!
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client at address 0x50 can not be probed - unload all client drivers first!
Client at address 0x54 can not be probed - unload all client drivers first!
Client found at address 0x69
Client found at address 0x73
Probing for `FSC Poseidon'... Success!
(confidence 8, driver `fscpos')
Probing for `FSC Scylla'... Failed!
Probing for `FSC Hermes'... Failed!
Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan the ISA bus? (YES/no): n
Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan for Super I/O sensors? (YES/no): n
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `lm75' (should be inserted):
Detects correctly:
* Bus `SMBus PIIX4 adapter at f0b0' (Algorithm unavailable)
Busdriver `i2c-piix4', I2C address 0x49
Chip `National Semiconductor LM75' (confidence: 6)
Driver `fscpos' (should be inserted):
Detects correctly:
* Bus `SMBus PIIX4 adapter at f0b0' (Algorithm unavailable)
Busdriver `i2c-piix4', I2C address 0x73
Chip `FSC Poseidon' (confidence: 
I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)? smbus
To make the sensors modules behave correctly, add these lines to
/etc/modprobe.conf:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----
To load everything that is needed, add this to some /etc/rc* file:
#----cut here----
# I2C adapter drivers
modprobe i2c-piix4
# I2C chip drivers
modprobe lm75
modprobe fscpos
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#----cut here----
WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
Do you want to generate /etc/sysconfig/lm_sensors? (YES/no): n
