I assume you're on a release 4 or newer sd card image. For a
speedgrade 1 device check out the following [1] file that contains the
devicetree (against the Xilinx 3.14 kernel we're shipping)
I'm working on making E3xx series run with mainline kernels (I have
something working for E310),
but E312 still needs some work. I'm hoping to be able to put that out
there with the release 5 series.
When adding peripherals to the FPGA with a kernel driver make sure
your drivers can deal with the peripheral in the PL going away on
reload. If you're building against the 3.14 kernels we ship you can
have your driver register for a notifier event [2]. (I'm working with
upstream to find a better solution with device tree overlays & fpga
manager). You can also unload / reload the module depending on the
type of peripheral.
Out of curiosity: What kind of peripheral are you adding?
Cheers,
Moritz

If you are building the file system from the manifest and instructions
the manual, the device tree file built into the image is here:

Hi Michael,
thank you for your davices.i tried it,but no use.But if i change to 158277B-01L
UBX,it works ok.Can UBX be flashed firmware,or some other measures i should
take?
best regards
Jon

Hi Jon,
There is no firmware on the UBX and there is no difference in software for
the different versions. What is the exact error you are seeing?
Regards,
Michael

With a recent image, it should just work.
Look in /etc/ntp.conf
Try ntpq -p
cgps should give state of gps.

Philip, do you mean the image that was just pushed in the last week (I
am running on the image before that)? Thanks for the quick response.
