Nope. this is also posted with the 'Black tag. dl4mea interjected a message

I don't see how to figure out whether uboot

Also, if you've got a USB serial cable, you can pause the startup

I attached a serial cable, but it doesn't say anything
After some debugging I found...
- I have to set fdtfile=am335x-boneblack-ttyO4.dtb in uEnv.txt, not
dtb=...
- uBoot loads the dtbs from /boot/dtbs, not from /boot/dtbs/`uname -r`,
which is where the dtb-rebuilder drops them
I have uBoot 2013.07, maybe some of the info pertains to a

I don't see how to make this stuff work... I used dtb-rebuilder to produce
the provided DTB with ttyO4:

About? I don't see any errors or so.

I just upgraded to kernel 3.14.4 and have now run headfirst into the lack
of capemgr. I had a nice DTS overlay file to enable ttyO4 with DTR/DSR/CTS
and that's now of course useless. Not only that, but the dts files
in https://github.com/RobertCNelson/dtb-rebuilder.git for ttyO4 are quite
files require hours of research and tinkering...

Another alternative is to use VLANs, assuming your switch supports that.
I'm using an ODROID as firewall/router and it also onlu has one ethernet
port, so I simply use two vlans. (The purists will say that this is not as
secure as two physical ports, but I'm ok with that.)
On Saturday,

Same problem here with the UART driver. I'm having difficulties with the
new enable_partno the cape manager fails to load my dtbo even through the
echo slots works just fine. I have:
$ cat /boot/uboot/uEnv.txt
optargs=fixrtc capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN

I've been wanting to combine my BBB with my Arduino hacking, specifically,

the right tool for that. For example, right now I have an arduino clone (a
