Hi,
I went to pick up my UmTRX this morning. \o/
It appears to start fine, but I'm hitting a couple issues trying to
connect OpenBTS to it:
transceiver won't start
=======================
I get the following errors when starting OpenBTS or the transceiver:
/home/stephane/Public/src/umtrx/openbts-p2.8/apps# ./transceiver
linux; GNU C++ version 4.7.2; Boost_104900; UHD_003.004.000-a52936a
ALERT 139976877029152 UHDDevice.cpp:434:open: No UHD devices found with address ''
ALERT 139976877029152 runTransceiver.cpp:94:main: Transceiver exiting...
/home/stephane/Public/src/umtrx/openbts-p2.8/apps# ./transceiver
linux; GNU C++ version 4.7.2; Boost_104900; UHD_003.004.000-a52936a
ALERT 139853627492128 UHDDevice.cpp:345:set_rates: Failed to set master clock rate
ALERT 139853627492128 UHDDevice.cpp:346:set_rates: Actual clock rate 1.3e+07
ALERT 139853627492128 runTransceiver.cpp:94:main: Transceiver exiting...
(This is with latest UHD from git://github.com/chemeris/UHD-Fairwaves.git
and latest openBTS from git://github.com/ttsou/openbts-p2.8.git )
I assume the first one ('No UHD devices...') is a transcient problem.
For the second issue I don't know whether this might be because the
firmware on the unit I received might not be the latest, or because I
really need to first upload the FPGA image (although I assumed ZPU wouldn't
start in that case); here's the console output in any case:
USRP N210 UDP bootloader
FPGA compatibility number: 8
Firmware compatibility number: 11
Production image = 0
Checking for valid production FPGA image...
No valid production FPGA image found.
Valid production firmware found. Loading...
Finished loading. Starting image.
TxRx-UHD-ZPU
FPGA compatibility number: 8
Firmware compatibility number: 11
LMS1 chip version = 0x22
LMS2 chip version = 0x22
00:1F:11:02:19:01
192.168.10.2
FPGA compilation error
======================
Assuming this is because of a missing/out-of-date FPGA image, I tried to
compile the latest (git) FPGA firmware:
cd UHD-Fairwaves/fpga/usrp2/top/N2x0/ ; make clean ; make UmTRXv2
but got the following error:
ERROR:HDLCompiler:1654 - "/home/stephane/Public/src/umtrx/UHD-Fairwaves/fpga/usrp2/top/N2x0/u2plus_core.v" Line 734: Instantiating <rx_frontend_sw> from unknown module <frontend_sw>
A quick `git blame` points to some changes in January but I wouldn't
know where to start fixing this (or maybe this is an issue with my
environemnt and not the code). In case this is the environemnt, I'm using
ISE 14.4 on Linux/amd64.

Hi,
Can anybody confirm the USB debug serial port settings. I have downloaded
the FTDI drivers and can connect. However I do not get any meaningful
output.
Based on the source code I assume the settings are:
· baudrate = 115200
· stop bits = 1
· parity = none
· flow-control = off
Regards
Craig

May i know the following specs
1. What is the tx and rx isolation of umtrx?
2. What is the power output in dbm of your umtrx?
3. How is the lna on the rx input and is an external lna and bpf
recommended?
4. What is the main advantage of umtrx compared to usrp by ettus?
Thanks!
Joel

Hi,
I have a couple questions about the RX PLL in the LMS chip:
- What are the various LOBUF for ? (1/2/3). Do they correspond the
the 3 input of the RX side ? I see they're controlled by the SELOUT
bits, but I have no idea how to choose. Should it be matched to
LNASEL_RXFE ?
- What's the expected levels of the LO harmonics ? In my tests I see
to measure around -10 dB for 3xLO and ~ -22 dB for 5x LO. Is there any
way to improve this ?
The method I used to measure is to feed 400 MHz narrow bw signal to
the input. Tune LMS to 400 MHz and measure the received strength, then
change the signal generator to TX a signal at 1.2 GHz and measure
again, then at 2GHz, and so on ...
Cheers,
Sylvain
Hi all,
A one more bit of good news - we've been assigned with a range of MAC
addresses we could use for UmTRX's. Many thanks for Openmoko Inc and
Harald Welte for generously offering this service to open-source
hardware projects for free!
Now we have to setup a procedure to make sure all UmTRX's get out of
the fab with unique MAC addresses.

Hi all,
Just to let everyone know - in addition to working on manufacturing
issues we're improving our UmTRX firmware and software support right
now. And today we've got dual-channel finally working. Thanks to
Andrew Karpenkov for his awesome work on implementing the second
channel support in FPGA!
I plan to push the pre-built FPGA image to the download area in the
during the weekend and Andrew will publish the FPGA code changes soon
too.
What's ahead of us is to teach OpenBTS to use the second channel of
UmTRX. This includes support of two independent channels and then
implementation of switched diversity receive.
