I have a VIM4 with a recent Khadas Ubuntu server image
Fenix 1.4 Ubuntu 22.04.2 LTS Linux 5.4.180
I have a serial console connected.
I notice that when I reboot the server, sometimes it does it fine, sometimes it does not.
When it doesn’t reboot automatically, I see this on the serial console and need to press Enter to boot up.

No problem when powering up, the problem occurs when I ask the system to execute the reboot command.
As you only connected the cable to VIM4 but not connect the dongle’s USB to your PC, so there may some interference from UART to stop the system booting process.
We suggest you to remove the uart cable from VIM4 if you don’t use it to avoid this issue.
And we will fix this issue. have a great weekend!!
