Nick, Ian,
If this unit happens to be incorrectly labeled as a rev 2 N210 and it
is actually a rev 3 N210, is there hope in being able to load rev 3
firmware and fpga images (which I have located previously and tried
actually) with some available UHD version? If so, would you be able
to tell me which UHD version(s) might be able to communicate with it?
Joe
Theoretically, most versions in the last several years should be able to
talk to it. In *general* UHD never drops support for older hardware,
and tries to maintain compatibility. Now, it is the case that newer
features are almost never "back-ported", but basic functionality should
always be there.
What this *should* mean is that you should be able to use the firmware
tools once the device is in "safe mode" to get yourself to where you
want to be. If that doesn't work, that may well mean that the
hardware is broken, and it's unlikely to be economical to repair.

Okay. I’ve asserted from the outset that it’s a rev 2, based on the
factory label. Is this N210 a lost cause if it is actually a Rev2 N210?

Well, it's not a rev 4. It's either 2 or 3 in terms of hardware
revision.

Ian,
Yes, I have tried many times to boot in safe mode, same result
regardless. Yes, I am able to pin to 192.168.10.2 successfully.

Ian and Nick,
Thanks for the assistance. Attached are dropbox links to two
snapshot photos: 1) the factory label on the back of the
N210, showing N210 r:2.0 and 2) a top side view of the N210.
1)

Seems this unit is indeed a rev 2 N210, yes?

Moreover, the best "tell" is to look at the N210 motherboard.
If the SRAM chip is on the top side, it's a rev 2/3. If the
SRAM is on the bottom side, it's a rev 4. If you send a
picture along of the top of the N210, I can tell you if it's
early or late rev.

Joe,
So I scratched my head about this a little late last
night and looked back through the development repository
for the N210 and as far as I can tell there was never
customer facing FPGA code for a Rev2 N210. Chatting with
Matt this morning he shared my feeling that a Rev2 wasn't
sold to customers, so I'm curious if you have a unit that
has a factory label that says N210Rev2 or if you have
seen "usrp2 rev2.0" on the PCB (which can be missleading).
Also have you tried booting into the safe image and
verifying that it at least pings on 192.168.10.2?
If we can conclusively identify which rev of h/w you have
I can probably help further.
Ian
