Hi all.
I found that both Rx divercity switches have zero state for A and B control
inputs.
Thus both LNA and LNA-D connectors are not switched to Rx inputs of the
LMS's.
To proceed Rx testing I suggest to set the next fixed states in the FPGA:
DIVSW1_P = 1, DIVSW1_N = 0, DIVSW2_P = 1, DIVSW2_N = 0.
In this case LMS1 will be switched to LNA connector, but LMS2 to LNA-D.
Andrew Karpenkov, would you please to make this kind changes, until DIVSW
will controled by host?
Best regards,
Andrey Sviyazov.
Hi all,
I've set maximum message size for this mailing list to 1Mb. This means
that you can't send big files or images to this mailing list. If you
need to do so - upload files to some external server and provide a
link. Project members could use our project hosting, others could
upload to some other public services.
At the same time limitation of 1Mb should be big enough to allow you
to post screenshots of your measurements, schematics pictures, etc.
Please make sure that you send big files as an attachments, even if
they are textual. Subscribers (myself included) sometimes work from
GPRS/EDGE connections and downloading huge e-mails is a true pain.

Hi All,
I added one more RX and TX units and connected them to the second LMS chip.
You can find fpga sources with full supply (both, receive and transmit) of
dual channel at akarpenkov/dual-channel branch of github repository.
Also, we need to make some changes in HOST code:
- SR_RX_FRONT0 (base adress of RX0 frontend) was changed from 24 to 20
(dec)
- SR_RX_FRONT1 (base adress of RX1 frontend) was added with value = 25
(dec)
- SR_TX_FRONT (base adress of TX0 frontend) was changed from 128 to 110
(dec)
- SR_TX_CTRL (base adress of control logic of TX0 channel) was changed
from 144 to 126 (dec)
- SR_TX_DSP (base adress of DSP TX0 unit) was changed from 160 to 135
(dec)
- SR_TX1_FRONT (base adress of TX1 frontend) was added with value = 145
(dec)
- SR_TX1_CTRL (base adress of control logic of TX1 channel) was added
with value = 161 (dec)
- SR_TX1_DSP (base adress of TX1 channel) was added with value = 170
(dec)
- Setting register to program the UDP TX DSP port (16 + 1 in dec) are
now 32 bit wide (udp dst0 port - lower 16 bits, udp dst1 port - higher 16
bits).
I sent flash for FPGA to Alexander and he must publish files on the
site soon.
I should say, I have not tested work of the project. Please report any
issues.
Regards ,
Andrew Karpenkov
Hi all,
I've pushed more public documentation for LMS6002D to the repository:
https://github.com/chemeris/lms6002-documentation
FAQ should be very interesting for everyone - recommended reading.

I need some time to read the post, but in general it's a good idea to
describe branching policy.

Hi Jean-Samuel,
Could you share the prices you get for UmTRX from your fab for this
batch of prototypes and for the next batches? We have to understand
the cost price to see what could we offer to customers.

Hi all,
As UmTRX release gets closer, i want to gradually move all related
documentation, discussions, news, etc to public. The plan is to move
everything under the Osmocom umbrella, because it's a good
neighborhood for UmTRX.
Omsmocom.org server is somewhat overloaded now, so for the time being
all git repos will stay at github and wiki and files will stay at
Google Code. They will be moved to osmocom.org when they upgrade their
server.
Mailing list is not a big load, so the UmTRX public mailing list has
been created as umtrx(a)lists.osmocom.org. Some of you already received
subscription e-mails, everyone else is encouraged to subscribe as
well. You could do that with the web interface here:
http://lists.osmocom.org/cgi-bin/mailman/listinfo/umtrx
Please use the public mailing list for all technical discussions from
now on. "Project-mayotte" and "gsm-internal" are to be used for
business and manufacturing related, private or other highly 533kr337
discussions.
I'm going to publish schematics today together with some brief
description of features. Public Lime documentation will be published
as well.
