A Nuvoton NCT7904 Hardware Monitor Chip (HWM) provides hardware monitoring
capabilities on the FWA-1320. The HWM chip is connector to the PCH's SMBus.
Standard software packages such as "lmsensors" can be used on the host to provide
sensor information under Linux. Advantech provides the required patch that adds
support for the HWM chip and a system specific configuration file.
Please contact your Advantech representative if you wish to receive the lmsensors
patch or, in case you want to implement your own hardware monitoring solution, to
obtain more details regarding the hardware implementation.
The HWM monitors all critical voltages on the FWA-1320:
Pin No. Pin Name
6 VSEN6
7 VSEN7
8 VSEN8
9 VSEN9
10 VSEN10
11 VSEN11
13 VSEN13
14 VSEN14
15 3VDD/VSEN15
16 3VSB
48 VBAT
Moreover, the following temperatures are supervised:
Pin No. Pin Name
2,3 TR1
The HWM also monitors the front and rear fans:
Pin No. Pin Name
29 FANIN_1
30 FANPWM1
31 FANIN_2
32 FANPWM2
In addition to the HWM, the ATOM C2000 CPU features integrated temperature sen-
sors (1 per core) that are supported by the "coretemp" module of lmsensors:
