Hi,
While I'm waiting for my umtrx to show up, I'm following the "let's play newbie" route and trying to use the instructions on https://code.google.com/p/umtrx/wiki/BuildingUHD
I got stuck for a short while on step #2. It would probably be useful to add at the beginning of step 2 something like:
git clone git://github.com/chemeris/UHD-Fairwaves.git
Also I see the FPGA instructions use ISE 14.2, should I download that version rather than the more recent one (14.4) on Xilinx' site?
Finally, is the Ethernet flashing going to work off-the-box on the beta umtrx or is it better I buy a JTAG cable? In that later case is the Digilent HS-1 the recommended cable? S.
Hi, Stephane,
You can use any ISE version above 14.1. UmTRX would shipted to you already flashed. But If you'll spoil UmTRX with a wrong image, you can unbrick it with JTAG cable only. For this purposes we use Xilinx Platform Cable USB and Digilent HS-1.

Given the price difference I'll go with the Digilent cable.

Another question wrt OpenBTS configuration, is it sufficient to do:
./configure --with-uhd
or does umtrx need other options (--with-resamp, --with-extref)?
Also I assume the transceiver code is the Transceiver52M version and I should just do
cd apps ln -s ../Transceiver52M/transceiver .
S.
At boot time, in USB debug port you can see such information as lms chip version, speed of Ethernet phy, MAC and IP address of UmTRX board (and much more, it's defined in ZPU bootloader firmware).

./configure --with-uhd or does umtrx need other options (--with-resamp, --with-extref)?
OpenBTS with UmTRX board required only --with-uhd option.

Yes, You're right.

Actually Farnell UK offers the HS-2 cable for 5€ less than the HS-1. From the specs they look similar (2012 vs 2011 version, some IEEE protocol added in HS-2), so I'll be getting the HS-2.
Ah, good to know, thanks. When I bought my cable, HS-2 cable did not exist yet.
Any news on when delivery will start for umtrx v2?
Yes, I apologize I haven't conveyed news earlier.
Bad news is that shipping of beta samples had been delayed. During detailed testing we found that many samples had manufacturing issues, so we sent them back to the fab.
Good need is that to this moment fab has found the problem (it was due to oxidation of some parts we bought earlier) and is working to fix it now. We expect to ship them very soon (end of the month or beginning of the next month) We're also making sure that next batch won't have these issues and will be shipped in time.
Thank you for bringing this up!
