transceiver won't start; fpga build error
by stephane＠shimaore.net 06 Mar '13

06 Mar '13

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0x22 00:1F:11:02:19:01 192.168.10.2 FPGA compilation error ====================== Assuming this is because of a missing/out-of-date FPGA image, I tried to compile the latest (git) FPGA firmware: cd UHD-Fairwaves/fpga/usrp2/top/N2x0/ ; make clean ; make UmTRXv2 but got the following error: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. S.

Dual channel
by joel yabut 05 Mar '13

05 Mar '13

What does dual channel actually mean? Can you use 2 different frequencies at the same time like 900 and 1800 or is it same band but different arfcn?

Debug port configuration
by Craig Reading 24 Feb '13

24 Feb '13

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

LMS RX PLL questions
by Sylvain Munaut 07 Feb '13

07 Feb '13

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

MAC address range for UmTRX has been assigned
by Alexander Chemeris 03 Feb '13

03 Feb '13

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. ---------- Forwarded message ---------- From: Harald Welte <laforge(a)gnumonks.org> Date: Mon, Feb 4, 2013 at 1:04 AM Subject: Re: Request for the OUI range for UmTRX board To: Alexander Chemeris <alexander.chemeris(a)gmail.com> Hi Alexander. 00-1F-11-02-19-00 to 00-1F-11-02-28-ff see http://wiki.openmoko.org/wiki/OUI#MAC_addresses Regards, Harald On Mon, Feb 04, 2013 at 12:08:45AM +0400, Alexander Chemeris wrote: > Hi, > > I'd like to request a range of 0xfff MAC addresses for the use with > UmTRX boards. > > Project information > ============== > > Name: UmTRX > Short description: UmTRX is a dual-channel wide-band SDR transceiver > with 1GbE connection. > Software License: GPLv3 > Hardware License: CC BY-SA 3.0 > Link: https://code.google.com/p/umtrx/ > Number of MAC addresses: 0xfff > > -- > Regards, > Alexander Chemeris. > CEO, Fairwaves LLC / ООО УмРадио > http://fairwaves.ru -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Dual-channel support on UmTRX
by Alexander Chemeris 03 Feb '13

03 Feb '13

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. -- Regards, Alexander Chemeris. CEO, Fairwaves LLC / ООО УмРадио http://fairwaves.ru
