The upgrade of crimson to Freebsd 11.0 was without incident, but upgrading opal, the wireless hub, based on an APU1D4 was more interesting.
The first problem was that buildworld ran out of space on /usr. The
storage needs of /usr/obj must have increased. To work
around this, I created an obj directory on /rep
(lots of space) and a softlink from /usr/obj to the
directory. I added the following line to the build script:
MAKEOBJPREFIXDIR=/rep/obj
The build of world and kernel succeeded, so I installed the new kernel and attempted a boot.
I could not connect via the local network. Ethernet port lights
were flashing, but opal would not talk to me. I dug out the serial
cable and conected up via cu -115200 (115200 is the default
baud rate of the APU1D4 serial port). No response to my
keypressess, not even garbled characters. At this point, I should
have thought about trying different speeds, but I didn't. Instead I
power-cycled the box, rebooting from the USB stick I had installed
FreeBSD from. This booted OK. At at this point I remember that I
had made changes to the USB image to run the console at 115200,
since the default for FreeBSD is 9600. This has not been copied
into the SSD.
The reason the bridge did not come up was that hostapd didn't match
the kernel. Once make installworld was run, that was
fixed.
So, for the record ...
[mark@opal:~]% cat /boot.config -P -S115200 [mark@opal:~]% cat /boot/loader.conf console="comconsole" boot_serial="YES" comconsole_speed="115200"
Note to self: if a cu line speed of 115200 fails, try 9600.
