hi all .

using snaphots of october 2nd and ports , i can compile x11vnc .
but it taks long hours ( about two days) .

i have memorized openbsd on beaglebone black(BBB)
openbsd on BBB is very small system , so it can run on everything ( for
example door , baby car  )

Building packages is only half as bad as it used to be since the pmap and cache
improvements patches got in. I've privately started building packages since 
ports
lock just to see how far I would get with 2 BBB. Pretty far, it turns out.

Enabling anything more than 1 bit modes on ommmc seems problematic
for reasons I've not been able to figure out.

Especially when writing data to emmc and reading it back which tends
to cause an io error with high modes.  I think 4 bit modes with an sd
card worked on bbb but doesn't on pandaboard.  The bbb emmc should be able
to do up to 8 bit modes if the right combination of clock setup/pin muxing/
whatever other setup is figured out.

There is a standard way of doing sdmmc dma, but the am335x ommmc doesn't
support that, so dma would have to be done by using the edma interface.

I don't think the armv7 bootloader has softraid support at present.
You could use mount_vnd(8) to crypt some partitions. However, I/O
performance on BBB is so bad that adding crypto on top is rather boring.

I use a BBB at home. It's a toy which works fine for simple network-bound
services but you can't make it do wifi or routing due to lack of USB support.
The USB port on BBB is driven by a non-standard host controller which is not
supported by OpenBSD yet.

If you're still figuring out what to buy, also take a look at other
boards listed on this page: http://www.openbsd.org/armv7.html
Freescale/NXP i.MX6 devices are currently the best supported ones but
they are more expensive than BBB.

If you're using the armv7 port you'll want to run -current in any case.

I'm expecting arm packages to re-appear some day soon.
But I'm not directly involved so I don't have any first-hand info.
And since I'm not working on it I'll be waiting very patiently.

Simply go to your favorite openbsd mirror and check the packages
directory. You will get up to date information about what packages are
available and which are not.
>From what I've seen, there is no package for armv7 / openbsd6.0. I
haven't checked snapshots.

FDE on BeagleBone Black

[L.R. D.S.]

Hi,
I'm thinking of buying a new toy board like BeagleBone Black to test the armv7 
port.
It's already possible to do full disk encryption on these boards?
Also, as a side question, I remember some discussion here on misc or tech, 
about no 
support for binary packages on armv7 port. Is it still right, I'll have to 
compile 
all by myself? I'm already feeling the pain to compile ffmpeg by myself...
Thanks in advance.
