Q: Why OLED is not display?

</div>

A: Please follow the steps below to check

1. Please confirm that the OS is correct according to your Raspberry Pi version:

Due to downloading the wrong firmware, the OLED cannot be displayed. We ALSO made such mistakes during testing

*For Raspberry Pi 4 : https://pikvm.org/download/

[[File:Pi4-V3-HAT.png|800px]]

*For Raspberry Pi Zero 2 W : https://docs.pikvm.org/flashing_os/

[[File:PiKVM V2 Platform.png|800px]]

2. Please check if the order of OLED screen pins is correct, please email to support@geekworm.com if it's a wrong pin order;

[[File:OLED-IMG-4373-1.jpg|800px]]

The run the following command to check the I2C address

sudo i2cdetect -y 1

<pre>

0 1 2 3 4 5 6 7 8 9 a b c d e f

00: -- -- -- -- -- -- -- --

10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --

40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

70: -- -- -- -- -- -- -- --

</pre>

3c is a hexadecimal number, it is the I2C address of OLED, if you can’t find this value, please shut down and reconnect shield and OLED, then run this command again, If you still can't find the OLED's I2C address, the OLED screen may be damaged.

'''PS''': Since the i2cdetect tool is not installed by default in pikvm os, you need to install it first. You can install it through the following command

<pre>

pikvm-update

rw

pacman -S i2c-tools -y

</pre>

4. Then run the following command to enable OLED display:

rw

systemctl enable --now kvmd-oled

ro

'''5.''' Please refer to https://geekworm.com/community/forum/topic/200314/kvm-a3-096-oled-display-is-dead if you can't solve the question.

</div>

Q: How to login pikvm os?

</div>

A: Input the XX.XX.XX.XX ip address on the explorer, then input user: admin, the default password is 'admin' also.

Or refer to [https://docs.pikvm.org/webui/#getting-to-know-the-interface GETTING TO KNOW THE INTERFACE]

</div>

Q: How to connect to wifi?

</div>

A: Refer to [https://docs.pikvm.org/first_steps/ | Optional setting up Wi-Fi]

If you want to connect KVM to a Wi-Fi network, you need to tell the device ESSID and password before first boot. To do this, mount the first partition of the memory card (FAT32) and edit or make the pikvm.txt file there. Do not remove line FIRSTBOOT=1 or FIRST_BOOT-1 for first time booting, just add your wifi settings like this:

<pre>

FIRSTBOOT=1

WIFI_ESSID='mynet'

WIFI_PASSWD='your password'

</pre>

There is a possibility that, in countries that support CH13, the device will not connect. You will need to configure your router to disable channels 12-14 or disable Auto scan mode so it will connect.

Save, unmount and follow the next step.

</div>

Q: How to switch root user?

</div>

A:

su root

#default password is root also

</div>

Q: Why does my PC stay in a continuous boot loop or act as if the power button is "always pressed" when using [[KVM-A3]]?

</div>

A: ~~Yes~~. ~~Refer to [[Enable pikvm hdmi audio]]~~</div>

A: This issue is typically caused by an incomplete cable connection, specifically the absence of the USB-OTG cable. Please ensure that all required cables are fully seated and connected before powering on your device.

Q~~. How to login pikvm os~~?

Q: Does [[KVM-A8]] support passive heatsink such as (P165-A or P165-B etc) instead of fan?

</div>

A: ~~Input~~ the XX.XX.XX.~~XX ip address on the explorer~~, ~~then input user: admin~~, ~~the default password is~~ '~~admin~~' also.

A: You can use the [[P165]] aluminium heatsink or the [[H402]] pure copper heatsink, but must remove the [[X630-A8]] fan and fan connector.

①If use '''P165-A'''(thickness 7mm), you can use '''M2.5*5mm''' spacer instead of '''M2.5*12mm''' spacer to fix it;

②if use '''P165-B'''(thickness 11mm), you can directly use '''M2.5*6mm''' screws to fix it;

③if use '''H402'''(thickness 4mm), you can use '''M2.5*8mm''' spacer instead of '''M2.5*12mm''' spacer.

You can also use other suitable spacers + screws to fix the heatsink.

<span class="tb_red">Q: Why is the [[X680]] not working?</span>

</div>

A: ~~Refer~~ to [~~https~~:~~//docs~~.pikvm.~~org/first_steps/~~ | ~~Optional setting up Wi-Fi~~]

A:

1. '''Firstly, must make sure the hardware expecially CM4 is connected correctly and securely.

* Check if the X680's onboard SYS-PWR, CM-PWR, CM-ACT LEDs are lit.

* If SYS-PWR LED is not lit, that means no power to X680; '''If the CM-PWR and CM-ACT LEDs are not lit, that means that the CM4 is not installed properly. Please recheck the CM4 installation, or check if the CM4 / X680 installation slot is damaged.(This is important! Many problems are caused by poor contact of CM4)'''

* If the X680's SYS-PWR, CM-PWR, CM-ACT LEDs are lit, then check the wiring connection.

Please refer to the following picture for the wiring connection and LED description.

[[File:X680-IMG-5523-Connection-Diagram-New.jpg|900px]]

[[File: X680-CM4-install1.jpg|800px]]

2. '''Make sure to use the right pikvm OS. Only PiKVM V3 is supported'''.

V3 Pre-Assembled version already includes OLED display configuration, while V3 HAT Kit version need to configuring OLED yourself.

Q: Why is USB mass driver not recognized on [[X680]]?

</div>

A:

A: Please refer to the description in the red rectangle in the picture below;

~~su root~~

~~#default password~~ is ~~root also~~

[[File:X680-usb-not-detected-faq.jpg|800px]]

The USB mass is not recognized in PIKVM OS, you can understand USB mass as a local USB HUB in PIKVM OS.

These 3 USB ports are used for local switching between target PC1-PC4, e.g. a USB disk with the OS image can be used to install the os in PC1, if switching to PC2, then the os can be installed in PC2, and so on.

</div>

Q: Does the [[X680]] support audio?

</div>

A: Yes. Refer to [[Enable pikvm hdmi audio]]</div>

</div>

Q: ~~Will there will be a case for~~ [[~~KVM-A4~~]]?

Q: Does the [[X680]] support PoE power? How to enable PoE Power?

</div>

A: No, ~~there is no plan~~ to ~~make a case for [[KVM-A4]],~~ the [[~~KVM~~-A4]] ~~kit can only use WiFi NOT ethernet, the match metal case will block the WiFi singal.~~

A: The X680 doesn't support POE, but you can use something similar to the [[PD3005G-3A]]

</div>

Q~~. Does~~ [[~~KVM-A8~~]] ~~support passive heatsink such as (P165-A or P165-B etc) instead of fan~~?

Q: Why can't I switch to another PC on [[X680]]?

</div>

A: You ~~can use the [[P165]] aluminium heatsink or~~ the ~~[[H402]] pure copper heatsink~~, ~~but must remove~~ the ~~[[X630-A8]] fan and fan connector.~~

A: You need to make sure that your target computer is not in '''sleep''', because when the computer is sleep, the USB port will stop supplying power

</div>

~~①If use '''P165~~-A~~'''(thickness 7mm)~~, you can ~~use~~ '~~''M2.5*5mm''' spacer instead of '''M2.5*12mm''' spacer~~ to ~~fix it;~~

Q: Why NVME SSD cannot be recognized on [[X680]]？

</div>

A: Login the pikvm web teminal, then type the following command:

lspci

The result of the command should look similar to the following, if you can't find something similar to the following, your NVME SSD is not compatible

</div>

~~②if use '''P165~~-~~B'''(thickness 11mm), you~~ can ~~directly use '''M2~~.5*~~6mm''' screws~~ to ~~fix it;~~

Q: How to boot from NVMe SSD on [[X680]]?

</div>

A: Refer to the following third-party tutorials:

* https://www.jeffgeerling.com/blog/2021/raspberry-pi-can-boot-nvme-ssds-now

You can also check out the official guide of the Raspberry Pi Foundation on how to boot CM4 from NVMe devices

* https://github.com/raspberrypi/documentation/blob/develop/documentation/asciidoc/computers/raspberry-pi/boot-nvme.adoc

</div>

~~③if use '''H402'''(thickness 4mm), you can use '''M2.5*8mm''' spacer instead of '''M2.5*12mm''' spacer~~.

~~You can also use other suitable spacers + screws to fix the heatsink.~~

Q: Can PiKVM work on Raspberry Pi 5？

</div>

~~[[File:IMG~~-~~2173~~-1.~~jpg|600px]]~~

A: Not yet, but it will in the future. The Raspberry Pi 5 does not support hardware video encoding, it's not recommended for PiKVM right now.

Please recheck the CM4 installation, or check if the CM4 / X680 installation slot is damaged.(This is important! Many problems are caused by poor contact of CM4)'''
+* If the X680's SYS-PWR, CM-PWR, CM-ACT LEDs are lit, then check the wiring connection.
+Please refer to the following picture for the wiring connection and LED description.

-If you want to connect KVM to a Wi-Fi network, you need to tell the device ESSID and password before first boot. To do this, mount the first partition of the memory card (FAT32) and edit or make the pikvm.txt file there. Do not remove line FIRSTBOOT=1 or FIRST_BOOT-1 for first time booting, just add your wifi settings like this:
+. <span class="tb_red">Important: Remove the USB cable after programming is complete. </span>
-<pre>
-FIRSTBOOT=1
-WIFI_ESSID='mynet'
-WIFI_PASSWD='your password'
-</pre>
-There is a possibility that, in countries that support CH13, the device will not connect. You will need to configure your router to disable channels 12-14 or disable Auto scan mode so it will connect.
-Save, unmount and follow the next step.
+. Please email us at <span class="tb_blue">support@geekworm.com</span> if you have further questions.

+The USB mass is not recognized in PIKVM OS, you can understand USB mass as a local USB HUB in PIKVM OS.
+These 3 USB ports are used for local switching between target PC1-PC4, e.g. a USB disk with the OS image can be used to install the os in PC1, if switching to PC2, then the os can be installed in PC2, and so on.
