Hi all!
Today the PCBs have arrived and I spent some tiem building the first
prototype. Soldering after a long time was quite fun but worked great.
However, I got stuck for way too long due to two pin-out problems:
* the voltage regulator pinout is completely mixed up
* the reset switch pinout is wrong and causes the device to be in nRESET
all the time
I've now applied some re-work and the CPU seems running. However, due to
some unknown (probably USB pull-up related) problem, I cannot see it
enumerate on USB yet.
Will keep you posted about my further progress.
I've created tickets for the bugs in our trac
(http://bb.osmocom.org/trac/query)
Regards,
Harald

Hi all,
JFYI: The components for the SIMTRACE prototypes have arrived. The PCB
will be shipping on June 9, so I guess it will arrive after the
whitsunday holidays and we should be able to build the first unit[s] on
June 14 or 15.
Kevin: Do you have some time around those dates?
Regards,
Harald

Hi!
It really seems like the FPCB (Flexible PCB) SIM card adapters have been
removed from the rebelsimcard.com store. A couple of months ago, you
could buy them separately from their "Hex Scanner".
I have sent them an inquiry indicating my interest in buying bulk
quantities (100 pieces). Let's see if that works. IF not, we may have
to develop a 'plan B' in this area :(
Regards,
Harald

Hi Kevin and others,
I've just ordered 4 prototype PCBs as well as components for at least 10
units. I'll keep you posted about the progress. We should have them in
less than two weeks.

Harald

Hi,
The BOM (bill of material) is ready.
I finished the netlist, footprint drawing, and footprint selection.
all available at : https://gsm.tsaitgaist.info/SIMtrace/v0.9+/
next task : place the components on the board (i'll try smart card size)
and route the lines.
Kevin
Hi,
softSIM is out : http://bb.osmocom.org/trac/wiki/softSIM
It's not fully implemented but already working (I hope).
The osmocomBB use/cooperation will come out soon.
Other tools are coming next week (I need to clean them).
Have fun,
tsaitgaist
Hi all!
As some of you already know, Holger and I have recently started a new
company called "sysmocom - systems for mobile communications GmbH".
The process of establishing the new company has now formally concluded.
Before some rumours start to spread, we would like to clarify some
points and make sure there is mutual understanding between the Osmocom
community and the sysmocom company.
sysmocom is intended to provide commercial offerings related to the
Osmocom projects. This is not entirely new. Especially on the network
side, people like Holger and I have been doing quite a lot of paid
development to bring those projects forward. We would not have many of
the features we have today, if it wasn't for customers who actually pay
us for development of OpenBSC, OsmoBSC, OsmoSGSN and the various side
projects more targetted at a real network operator like cellmgr-ng,
bsc-nat, gb_proxy - just to name a few.
However, this has always only been freelancing development of Software.
With sysmocom, we want to go one step further and work on hardware
products related to the various Free Software projects. Right now I
don't want to talk too much about unfinished products, but we are
working towards an inexpensive BTS product, we are funding the
prototypes for Osmocom SIMtrace, and we will likely also see stuff like
OpenBSC appliances.
Given our past involvement and exposure into other projects that share
a split Free Software / business set-up, we think we understand very
well where potential issues of conflict between the two sides may be.
Let me make some more clarification what this is not about:
* sysmocom is not about creating proprietary derivates of Osmocom
software. We work on Free Software which is publicly available under
OSI approved and FSF endorsed licenses. We may offer proprietary
hardware and sometimes software - but those are independent projects
from existing Osmocom software.
* we specifically will not have a public and a non-public version of
the same program with differences in features.
* sysmocom is not a VC-funded startup. It's a very small company
run out of personal funds with no intention to take external funding
or grow rapidly. Nobody but Holger and I determine where it goes
and what it does.
* sysmocom does not hold any copyright on the Free Software projects.
The copyrights stay distributed with the major authors such as Holger,
Onwaves, Sylvain, Dieter, Andreas and myself. None of the others have
any affiliation with sysmocom. I have (personally, unrelated to
sysmocom) asked some of the smaller contributors for a copyright
transfer to make sure we could do the AGPLv3 transition, or future
re-licensing decisions without having to ask dozens and dozens of
people. sysmocom does not seek to control the Free Software projects.
* we will maintain a strict separation between the community side of
things and the business side. Unlike some other popular projects, we
will not end up in a situation where the osmocom.org websites will be
full of advertisements and hidden links that lure you on the company
website.
* we will keep a strict separation of naming. Osmocom is for the FOSS
projects, sysmocom for the business. The company will use the term
"Osmocom" only in descriptive context, not as a product name, brand
or for advertisement.
If you do have any concerns, please feel free to share them. However,
I'd like to avoid cross-posting them throguh different mailing lists.
Please follow-up-to openbsc(a)lists.osmocom.org
Regards,
Harald

Hi all!
The kicad project for the simtrace hardware that Kevin has been working
on is now available as part of the simtrace.git repository on
git.osmocom.org.
This will allow us to document the revision history of any modifications
to the hardware in the commit messages, and it allows us to see
differences between individual versions.
Regards,
Harald

hi,
here v0.8 : https://gsm.tsaitgaist.info/SIMtrace/v0.8/
Compared to v0.7+, I added 2 1n4148 after the parallel voltage regulator
outputs.
I wanted to avoid the regulators to fuzz each other, but I don't know if
it's right. Maybe an additional zener diode is also required.
Now I'm looking for the parts and footprints.
