I have an apu1d4 and I am very happy with it. There is, however, a strange issue with the serial console.
The system runs FreeBSD 10 and I connect via a Mac (FTDI Serial Adapter, http://www.ftdichip.com/) using the "screen" program.
When I set the console speed to the recommended 115200 baud (in FreeBSD on the APU) and have the adapter connected to my Mac, everything works as advertised. BUT when I disconnect the adapter and reboot the APU, it does not boot until I connect the serial adapter and hit <ENTER>. It seems to "hang" and/or wait for some sort of confirmation before booting up.
The problem goes away when I lower the console speed to 9600...
As I usually access the system via SSH and only want to use the serial console in "emergency" situations (i.e. when I loose SSH access) it's not a big issue. I do not really care if access is a bit slower in an emergency. But I still find the fact that 115200 seems to have such a strange (to me) issue slightly irritating.
Ah yes, keeping the console cable connected at all times is not really an option :) I'd rather go with the 9600 bauds then.
Wondering if anyone has a hint?
