Intel NUC NUC5i5MYBE {#nuc5}
|
||
|
|
====================
|
||
|
|
|
||
|
|
Pinmuxing on the 5th generation Intel NUCs is done in the BIOS. This is only
|
||
|
|
tested on bios 0024+ (MYBDWi5v.86A). By default the custom solution header is
|
||
|
|
disabled, currently in Linux (as of 4.2). Both i2c buses are currently
|
||
|
|
supported.
|
||
|
|
|
||
|
|
The NUCs supported are the NUC5i5MYBE & NUC5i3MYBE which also come as the
|
||
|
|
NUC5i5MYHE and NUC5i3MYHE motherboards. It's possible that others expose the IO
|
||
|
|
in a very similar way so could be supported, get in touch if you have one!
|
||
|
|
|
||
|
|
In the BIOS you are required to enable the following:
|
||
|
|
Devices -> Onboard Devices - GPIO Lockdown
|
||
|
|
Select I2c under GPIO for the 12/13 14/15 pins
|
||
|
|
|
||
|
|
Interface notes
|
||
|
|
---------------
|
||
|
|
|
||
|
|
**I2C** Depending on your system you may need to load `i2c-dev`
|
||
|
|
|
||
|
|
Custom Solutions Header mapping
|
||
|
|
-------------------------------
|
||
|
|
|
||
|
|
The mapping is the same as the DE3815tykhe.
