===How to control fitlet2 front LEDsin Linux?===
==== <ins>For Linux</ins> ====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 To control the GPIOs need to login as root (root password required): $ su Password: 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 The GPIO framework and GPIO sysfs interface are documented inhttps[[Linux Mint://www.kernel.org/doc/Documentation/gpio/gpio.txtMobile broadband]]

===I can see an additional COM port in the device manager, where is it physically?===
*fitlet2 comes with a single RS232 ultra-mini com port (COM1)
*There is another COM ports inside the chassis (COM2) for the use of developing additional FACET cards.
*That The additional COM port is no not accessible externally whatsoever.
===What is the DC input voltage tolerance for the fitlet2?===
The fitlet2 model can work at a wide DC input voltage range of 9V-20V.
<br>This range can also be extended to 9V-36V if the model is configured with the P36 option.
 
=== What is the fitlet2's RTC backup battery accuracy?===
 
* 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 sold in the set of cables package for the fitlet2 - [https://fit-iot.com/web/product/accenc-adflt2/ fitlet2 set of cables]
==Software==
===Custom How do I Enable PXE boot?=== * Enter BIOS configurations for OPNsensemenu by pressing "ESC" on startup* Navigate to '''Advanced''' --> '''Network Stack Configuration'''* Set Network stack to '''[Enabled]'''* Configure boot option #1 to '''[Network]''' at Boot tab* Save changes and exit by pressing '''[F4]''' and accepting. ===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
1. Download the FreeBSD release from https://www.freebsd.org*Enable Wake on Lan and Save&Exit by pressing '''[F4]'''
$ wget https://download.freebsd.org/ftp/releases/amd64/amd64/ISO-IMAGES/11.1/=== FreeBSD-11.1-RELEASE-amd64-memstick.imgis not working, what can I do?===
2There are necessary configuration changes that should be made in order to have FreeBSD work on fitlet2. Prepare bootable disk-on-key (assuming /dev/sdX is your disk-on-key)<br>Press '''[Del]''' during boot to enter BIOS settings and set the following to:
$ sudo dd if=FreeBSD Chipset -11.1> South Cluster Configuration -RELEASE> SCC Configuration -amd64> SCC SD Card Support '''[Disabled]''' Chipset -memstick.img of=/dev/sdX bs=1MB> South Cluster Configuration -> SCC Configuration -> SCC eMMC Support '''[Disabled]''' Chipset -> South Cluster Configuration -> SCC Configuration -> SCC SDIO Support '''[Disabled]'''
3. Necessary BIOS settings changes:===How to identify the COM port on Linux ?===
Press [Del] during boot Please refer to enter BIOS settingsthe link- [[Linux Mint:Serial port on fitlet2]]
Set Chipset -> OS Selection ===fitlet2 BIOS Legacy boot doesn't work, how to [Intel Linux] Set Chipset -> SCC Configuration -> SCC SD Card Support (D27: F0) to [Disable] Set Chipset -> SCC Configuration -> SCC eMMC Support (D28: F0) to [Disable] Set Chipset -> SCC Configuration -> SCC UFS Support (D29: F0) to [Disable] Set Chipset -> SCC Configuration -> SCC SDIO Support (D30: F0) to [Disable]enable?===
4. Power on Legacy support is disabled by default in the fitlet2, you will see boot process and "Welcome to FreBSD!" messageBIOS 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'''
=== Linux mint audio codecs do not load properly ===
* The BIOS configuration called "OS selection" at the main menu reflects on how the system loads the audio codecs.
* Changing the OS selection may result with strange sound card behavior, even when returning manually to previously selected option.
* Restoring the machine to its default values may fix this issue:
# Press [Del] during boot to enter BIOS setting
# Press F3 (Optimized Defaults) In the BIOS setting
# Keep the OS selection to Windows - Do not change.
## '''Note''': For Mint Box mini 2 machines, the default is set to "Linux" - Do not change.
# Press F4 (Save & Exit).
* At this point the machine should turn on with BIOS set to defaults and OS selection should be set to "Windows".
* This configuration can be kept for both Linux and Windows.
