i recognized following issue.
APU4C4 connected with usb stick prepared with ippfire.
Connected with serial adapter via minicom (linux).
Booting via stick and installing ipfire with serial options.
Connection with serial adapter works fine.
Install ipfire 2.25 core 144 on APU4. After installing and first reboot you can configure your fresh installed system. But it hangs at setting admin password…
Same at ipfire 2.25 core 143
When using ipfire 2.23 core 139 first configuration works fine with serial console. After setting admin password you will get network configuration.
Updating to latest & greatest works fine.
Please have a look to it.
