I added the line to my local.conf:

rw at linux-cyy8:~/poky-dora/build> grep nfs conf/local.conf
DISTRO_FEATURES_append = " nfs"
CORE_IMAGE_EXTRA_INSTALL += "nfs-utils"
rw at linux-cyy8:~/poky-dora/build>

Then

rw at linux-cyy8:~/Downloads/poky-dora-10.0.1/build> bitbake core-image-basic

rw at linux-cyy8:~/Downloads/poky-dora-10.0.1/build>

(this was not the first time I had run this command; the previous one was a
...-c clean)

I still seem to be missing things: There is no mount.nfs that I can find

rw at linux-cyy8:~/Downloads/poky-dora-10.0.1/build/tmp/deploy/images/zedboard-zynq7>
tar -tzf core-image-basic-zedboard-zynq7.tar.gz | grep nfs

???

I even tried deleting tmp and sstate-cache and starting over...
Same result.

==============================================================

Ok, how about using eclipse?
I tried following the project development manual documentation, and got as
far as 4.2.2.3 step 3:

Select "Reconfigure Project" from the "Project" menu.

There does not seem to be such a menu item. Oh, that should have read
'Select "Reconfigure Project" from the Project right-click menu'

So, reconfigure project: That fails.

configure:3166: arm-poky-linux-gnueabi-gcc  -march=armv7-a
-mthumb-interwork -mfloat-abi=softfp -mfpu=neon
--sysroot=/opt/poky/1.5.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi
-qversion >&5
arm-poky-linux-gnueabi-gcc: error: unrecognized command line option
'-qversion'
arm-poky-linux-gnueabi-gcc: fatal error: no input files
compilation terminated.

???

Sigh.

==============================================================

And for some reason I can't get minicom to work. Or even picocom, for that
matter.
I set the device to /dev/ttyUSB0, the baud rate to 115200. Nothing.
Here's the picocom try:

rw at linux-cyy8:~/eclipse> picocom -b 115200 /dev/ttyUSB0
picocom v1.6

port is        : /dev/ttyUSB0
flowcontrol    : none
baudrate is    : 115200
parity is      : none
databits are   : 8
escape is      : C-a
local echo is  : no
noinit is      : no
noreset is     : no
nolock is      : no
send_cmd is    : sz -vv
receive_cmd is : rz -vv
imap is        :
omap is        :
emap is        : crcrlf,delbs,

Terminal ready

Return does nothing. And Ctrl/A doesn't seem to do anything, either.
I've been using my laptop & windows to connect to the console.

When I was using Suse 13.1, minicom was working once. If I cycled
power on the zedboard, I couldn't reconnect. When I went back to
13.1, it didn't seem to work at all. Reboot to windows and it works fine.

???

Sigh.

============================================================
and the boot process is unreliable.
I'll start a separate thread on that.
