[D3446-S] Mainboard Sensors

Postby chrisb » Tue Jun 27, 2017 17:17

i am trying to get all sensors (voltage, temperature, fans) to work on the D3446-S Mainboard (http://www.fujitsu.com/uk/products/computing/peripheral/mainboards/industrial-mainboards/d34462s.html) under Linux. There is a driver package for System Monitoring: http://www.fujitsu.com/uk/products/computing/peripheral/mainboards/industrial-mainboards/d34462s.html available from Fujitsu. As I am using a very recent kenel (4.11 on Arch Linux) i am using the ftsteutates driver which is included in the kernel.

After the kernel module is loaded, it shows all sensor raw values, but there seems to be no conversion to real-life values. I got the FAN + Temperature correction factors by reading the ftsteutates.c source code, but could noch figure out the voltage conversion for the voltage inputs.

Is there any documentation about the voltage dividers and channels assignments for the ADC inputs of the Teutates chip on the D3446-S ?

Output from lm_sensors (notice the "Volt:" values):

Code: Select all

Adapter: SMBus I801 adapter at f040
Volt: VCC  ( 3.3V):  +0.23 V 
Volt: AUX  ( 3.3V):  +0.23 V 
Volt: V_IN (12.0V):  +0.23 V 
Volt: VBAT ( 3.0V):  +0.21 V
Fan: CPU:            360 RPM
Temp: CPU:           +30.0°C 
Temp: Ambient:       +31.0°C 
Temp: Core:          +38.0°C 
Temp: Memory:        +31.0°C 
Temp: PCH:           +48.0°C 
Temp: Graphics:      +33.0°C

Is this the right forum ? I could not find any Mainboard specific section..

Anyways, there is are TechNotes on the ftp Server: ftp://ftp.ts.fujitsu.com/pub/Mainboard-OEM-Sales/Products/Mainboards/Industrial&ExtendedLifetime/D344x-S/Documentation/TechNotes/.

Can someone tell me if there is any information about the Teutates chip inside or who to contact to get access to the file ?
