Config for PiKVM OS

"Because the blikvm hardware implementation scheme and PiKVM hardware implementation scheme are not exactly the same, you need to modify some errors through the following configuration for the official image of PiKVM. Of course, you can use the configured image."

Fan config

"Since BliKVM's fan hardware is different to PiKVM's, you need to replace the control fan script first. The following default starting fan temperature is 40 degrees Celsius"

su -
rw
git clone https://github.com/blikvm/blikvm.git
cd blikvm/package/kvmd-fan
bash install-kvmd-fan.sh
ro

"Edit the /etc/kvmd/override.yaml file and add the following content to remove the web UI error warning about fans."

kvmd:
    info:
        fan:
            unix: ''

Check EDID file for 1080P60Hz input

"The function of the EDID file is to set the controlled computer to input according to the expected resolution. Since the image EDID file of PiKVM in different periods does not necessarily meet 1080P60Hz, when you use the CM4 version of hardware, it is found that the default output of the controlled computer is not 1080P60Hz, you can modify /etc/kvmd/tc358743-edid.hex to the following contents"

"make sure /boot/config.txt has the 4lane=1 entry in it for 1080p60hz support"

# Video and audio
dtoverlay=tc358743,4lane=1
dtoverlay=tc358743-audio

"If you use webrtc can't get audio, try to edit /etc/kvmd/janus/janus.plugin.ustreamer.jcfg to add audio support."

audio: {
    device = "hw:0,0"
    tc358743 = "/dev/kvmd-video"
}

OLED

"Follow the method below to enable OLED."

If you use PiKVM official image, log in to PiKVM and run these commands:

# rw
# systemctl enable --now kvmd-oled //Enable OLED
# ro

If the oled still can't work, you need to check whether there has "dtparam=i2c_arm=on" in "/boot/config.txt" file, and whether there has "i2c-dev" in "/etc/modules-load.d/i2c.conf" file. If not, please create and add them. If it still does not work after the above configuration, please burn the image provided by blikvm for testing to check whether the OLED hardware is damaged.

Config about v4mini image

If you want to PiKVM v4mini image for blikvm v1 and v2, because v4mini image uses different gpio pins for ATX controls, so you will need the following override if you want to run v4mini image on your blikvm v1 or v2 version and be able to use ATX controls; if you don't make this change, ATX controls won't work properly (the led pins are different); Edit the /etc/kvmd/override.yaml file and add the following:

kvmd:
    ### disable fan socket check ###
    info:
        fan:
            unix: ''
    atx:
        hdd_led_pin: 22
        power_led_pin: 24
        power_switch_pin: 23
        reset_switch_pin: 27
        type: gpio
    gpio:
        scheme:
            __v3_usb_breaker__:
                pin: 5
                mode: output
                initial: false
                pulse:
                    delay: 0
