crakeyboy Posted 3 hours ago Posted 3 hours ago the issue is as follows: 1. When using the Type-C interface to connect to an external monitor, the display works normally if the monitor is connected after the development board has started. 2. If the monitor is disconnected and then reconnected after approximately several hours (possibly more than 6 hours), the display fails to show any image. I used the `armbianmonitor -u` command, and it output the following URL. https://paste.armbian.com/foyecusoju If the Type-C interface is functioning normally, the latest output from `dmesg -w` would show the following: [ 1155.922647] xhci-hcd xhci-hcd.15.auto: xHCI Host Controller [ 1155.922692] xhci-hcd xhci-hcd.15.auto: new USB bus registered, assigned bus number 7 [ 1155.922885] xhci-hcd xhci-hcd.15.auto: hcc params 0x0220fe64 hci version 0x110 quirks 0x0002008002010010 [ 1155.922937] xhci-hcd xhci-hcd.15.auto: irq 116, io mem 0xfc000000 [ 1155.923133] xhci-hcd xhci-hcd.15.auto: xHCI Host Controller [ 1155.923152] xhci-hcd xhci-hcd.15.auto: new USB bus registered, assigned bus number 8 [ 1155.923173] xhci-hcd xhci-hcd.15.auto: Host supports USB 3.0 SuperSpeed [ 1155.923455] usb usb7: New USB device found, idVendor=1d6b, idProduct=0002, bcdDevice= 6.01 [ 1155.923476] usb usb7: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 1155.923491] usb usb7: Product: xHCI Host Controller [ 1155.923502] usb usb7: Manufacturer: Linux 6.1.115-vendor-rk35xx xhci-hcd [ 1155.923515] usb usb7: SerialNumber: xhci-hcd.15.auto [ 1155.924750] hub 7-0:1.0: USB hub found [ 1155.924811] hub 7-0:1.0: 1 port detected [ 1155.925434] usb usb8: We don't know the algorithms for LPM for this host, disabling LPM.
