===How to control fitlet2 front LEDsin Linux?===
See [[Application note - fitlet2 has 2 controlling front LEDs, LED1 and LED2. Each of them has GREEN and YELLOW parts that can be controlled separately.on Linux]]
In ===How do you I configure my cellular modem on Linux kernel there are 4 related GPIOs: GPIO435, GPIO436, GPIO437, GPIO438.?===*GPIO435 Please refer to the guide - LED1 GREEN*GPIO436 - LED1 YELLOW*GPIO437 - LED2 GREEN*GPIO438 - LED2 YELLOW[[Linux Mint: Mobile broadband]]
To control the GPIOs need to login as root (root password required):====<ins>For Windows</ins>==== $ su Password:TBD
To control for example LED1 GREEN part: $ echo 435 > /sys/class/gpio/export $ echo out > /sys/class/gpio/gpio435/direction $ echo 1 > /sys/class/gpio/gpio435/value # LED1 should be GREEN now $ echo 0 > /sys/class/gpio/gpio435/value # LED1 should be OFF now $ echo 435 > /sys/class/gpio/unexport===I can see an additional COM port in the device manager, where is it physically?===
The GPIO framework and GPIO sysfs interface are documented in*fitlet2 comes with a single RS232 ultra-mini com port (COM1)https://www*There is another COM ports inside the chassis (COM2) for the use of developing additional FACET cards.kernel.org/doc/Documentation/gpio/gpio.txt*The additional COM port is not accessible externally
===I can see an additional COM port in the device manager, where What is it physicallythe DC input voltage tolerance for the fitlet2?===
*The fitlet2 comes with model can work at a single RS232 ultrawide DC input voltage range of 9V-mini com port20V.*There <br>This range can also be extended to 9V-36V if the model is another COM ports inside configured with the chassis for the use of developing additional FACET cardsP36 option. === What is the fitlet2's RTC backup battery accuracy?=== *That additional COM port RTC accuracy – less than 1 sec per day === How can I get S/PDIF to work on my fitlet2?===The fitlet2 3.5 Audio jack has a 4th pin that outputs digital audio.<br>In order for this to work, there's a need for a 4-pole 3.5mm to RCA cable.<br>This cable is no accessible externally whatsoeversold in the set of cables package for the fitlet2 - [https://fit-iot.com/web/product/accenc-adflt2/ fitlet2 set of cables]

===How Do I Enable Wake-On-Lan (WOL)?===
 
*Enter BIOS menu by hitting '''[ESC]''' on startup
*Navigate to:
Chipset Tab
--> South Cluster Configuration
--> Miscellaneous Configuration
* Wake on Lan should be there '''[Disabled]''' by default
 
*Enable Wake on Lan and Save&Exit by pressing '''[F4]'''
 
=== FreeBSD is not working, what can I do?===
 
There are necessary configuration changes that should be made in order to have FreeBSD work on fitlet2.<br>
Press '''[Del]''' during boot to enter BIOS settings and set the following to:
 
Chipset -> South Cluster Configuration -> SCC Configuration -> SCC SD Card Support '''[Disabled]'''
Chipset -> South Cluster Configuration -> SCC Configuration -> SCC eMMC Support '''[Disabled]'''
Chipset -> South Cluster Configuration -> SCC Configuration -> SCC SDIO Support '''[Disabled]'''
 
===How to identify the COM port on Linux ?===
Please refer to the link- [[Linux Mint: Serial port on fitlet2]]
===fitlet2 BIOS Legacy boot doesn't work, how to enable?===
Legacy support is disabled by default in the BIOS menu.<br>
To enable it, please, set the following BIOS menu settings:
1. Advanced -> CSM Configuration -> CSM Support : '''[Enabled]'''
2. Advanced -> CSM Configuration -> Boot option filter : '''[Legacy only]'''
3. Advanced -> CSM Configuration -> Network : '''[Legacy]'''
4. Advanced -> CSM Configuration -> Storage : '''[Legacy]'''
5. Advanced -> CSM Configuration -> Video : '''[Legacy]'''
6. Advanced -> CSM Configuration -> Other PCI devices : '''[Legacy]'''
7. Boot -> Boot Mode Selection : '''[Legacy]'''
8. Press the '''F4''' key to '''Save & Exit'''
