Couldn't get connectivity to Motorolla c118 on writing osmocombb

by baymax Robo

Hi, I am trying to write osmocombb to Motorolla c118 phone by following the given [1] guide.I have successfully compiled firmware binaries but having issues while writing them to phone. I connected motorolla c118 via USB Serial To RS232 TTL to 2.5mm audio jack, using the given guide [2] When I run this command $ dmesg | grep tty I get the following output [ 0.000000] console [tty0] enabled [ 14.946936] usb 3-6: pl2303 converter now attached to ttyUSB0 [ 973.747957] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [ 1484.595816] usb 3-6: pl2303 converter now attached to ttyUSB0 [ 1845.344494] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [ 2643.566407] usb 3-6: pl2303 converter now attached to ttyUSB1 And on running this $ sudo cu -l /dev/ttyUSB1 -s 115200 I get a connected message but no further progress is done. When i press Power button briefly, no activity is shown. I have tried with two phones but no success on any. I have checked the connectivity between headphone jack and USB serial chip via voltmeter, it is fine as well. Also tried by doing Master reset on phone but no use. What can be issue and how can i fix it. ? Kindly ignore any mistakes, i am new to this domain, couldn't find much help on google as well :( [1] https://osmocom.org/projects/baseband/wiki/Software_Getting_Started https://osmocom.org/projects/baseband/wiki/Osmocon [2] http://www.linuxx.eu/2014/09/osmocombb-hardware-and-software-setup.html [2]

Osmocombb with USRP

by Snehasish Kar

Hi Herald I needed some information from you, I want to implement a GSM Mobile stack with USRP as RF Frontend. Is it possible to build the DSP part of osmocommbb in a different TI DSP board other than calypso. As it is very difficult to find calypso phones now a days. BR Snehasish

Re: OsmocomBB compile testing / Re: libosmocore embedded build

by Craig Comstock

I was thinking about how to setup an automated real device test for the repo and/or PRs especially. I have devices and cables, just was thinking about how to automate the re-loading of firmware (via an interface to the power button I suppose). Any work ongoing on this front? I'd be happy to contribute as I have a server I'm going to use for nano3g, calypsobts, development. -Craig -------------------------------------------- On Thu, 5/18/17, Harald Welte <laforge(a)gnumonks.org> wrote: Subject: OsmocomBB compile testing / Re: libosmocore embedded build To: "André Boddenberg" <dr.blobb(a)gmail.com> Cc: baseband-devel(a)lists.osmocom.org, "OpenBSC" <openbsc(a)lists.osmocom.org>, "Vadim Yanitskiy" <axilirator(a)gmail.com> Date: Thursday, May 18, 2017, 1:24 PM Hi Andre and others. We currently have a series of patches from Vadim pending in gerrit for OsmocomBB. They cannot move ahead, as we have no compile testing / jenkins job which would give this a +1. To resolve this, we should also start to have a jenkins compile testing job for OsmocomBB. The "host" (PC) part of the code is built against regular libosmocore, just like e.g. openbsc or osmo-bts. That should be possible even so far, and it might make sense to start with that. Basically you need to: * git clone osmocom-bb * cd src/host/layer23 * regular 'autoreconf -fi && ./configure && make' compile-testing the 'embedded' (firmware) part is not possible easily in the current master. However, as a second step, and after the libosmocore embedded build has run (and it is installed to /usr/local/arm-none-eabi), and if you use the laforge/remove-libosmocore branch in OsmocomBB, you should also be able to compile-test the firmware using * git clone osmocom-bb * cd src/target/firmware && make There currently is no "make check" tests for either the host utilities or the firmware, and of course we have no clue if the resulting binaries will do anything useful on an actual pone [yet!], but I still think the two steps above would be very useful to move ahead, and to unify the patch submission/review/verification/approval/merge process in gerrit with what we have established for the network-side projects like OsmoBTS & co.

OsmocomBB build verification

by Harald Welte

Hi Vadim, see attachment. This was my 'test ballon': We now have automatic jenkins build verification at least for the host part of OsmocomBB. Please re-push your patch series again into jenkins, so they will get build-verified. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

libosmocore embedded build

by Harald Welte

Dear all, when we originally moved a lot of generic code from OpenBSC to libosmo{core,gsm} to re-use it from OsmocomBB, we created an 'embedded' build of libosmocore, which can use [most of] the library code also in deeply embedded, OS-less 'bare metal' microcontroller environments. The ability to build libosmocore this way has been broken for many years, but I've fixed that in recent libosmocore master. Below command works for me [tm]: ./configure --prefix=/usr/local/arm-none-eabi \ --host=arm-none-eabi \ --enable-embedded \ --disable-shared \ CFLAGS="-Os -ffunction-sections -fdata-sections -nostartfiles -nodefaultlibs" What we'd need now is: 1) make sure embedded builds continue to work by building libosmocore for embedded as part of the jenkins setup (using gcc-arm-none-eabi debian package). Any volunteers? 2) start to use this embedded build from simtrace2 firmware, osmocom-bb and the upcoming fimrware for the RFDN[1]. So far, * osmocom-bb uses an old clone of libosmocore, * simtrace2 is using some copy+pasted fork of some libosmocore files * rfdn is using some copy+pasted fork of some libosmocore files The above is no longer required. 3) consider if we can shrink the resource requirements of some libosmocore parts. One issue coming up are the static buffers in osmo_hexdump[] or the like. If your total processor RAM is 8k or 16k, then spending 4k on the buffer for hex-dumping is indeed a bit excessive. Any help is appreciated, particularly on the jenkins side. Regards, Harald [1] (1:8 splitter-combiner with adjustible step attenuators, part of the osmo-gsm-tester setup we're building at sysmocom). Code will be released as soon as the hardware is validated. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

As I can see from the console output, build fails because we are trying to test disabled features, which we haven't compiled.

My build seems to work but when I run "make check-am" in tests I get a different error related to talloc. This is on a Debian 8 stable box using arm-none-eabi and newlib from debian packages.

Re: removing ancient libosmocore fork from osmocom-bb.git

Hi Harald and Craig, > select.c:27:24: fatal error: sys/select.h: No such file or directory > #include <sys/select.h> I have the same issue with: gcc-arm-none-eabi 4.8.2-14ubuntu1+6 binutils-arm-none-eabi 2.24-2ubuntu2+4 libnewlib-arm-none-eabi 2.1.0-3 > * remove 'talloc emulation' from osmocom-bb and use pseudotalloc from > libosmocore.git (plus an embedded 'malloc' like umm_malloc) Why do we need this hack (pseudotalloc)? What if we could cross-compile libtalloc too, and link it against core? > * have an (optional?) osmocom-bb makefile step to git clone + configure > + make install libosmocore Great idea! What about to have libosmocore as a git submodule inside OsmocomBB (like OpenCL headers in hashcat)? Also, I think it would be good to make libosmocore more modular, because it could allow us to create more flexible builds (e.g. to compile only what we need, not a whole library). This makes sense in case of low RAM / ROM embedded systems. What do you think? With best regards, Vadim Yanitskiy.

As libosmocore was quite a bit in flux (and we didn't have jenkins+gerrit yet), we decided to have a local clone of libosmocore.git as a git-subtree module inside osmocom-bb.git Meanwhile, upstream libosmocore received more and more code, and none of that was ever built with an 'arm-non-eabi' toolchain and --enable-embedded. I've been working quite a bit during the last week on making that embedded build work again. The idea is to be able to configure + build libosmocore.git master using something like ./configure --prefix=/usr/local/arm-none-eabi \ --host=arm-none-eabi \ --enable-embedded \ --disable-shared \ CFLAGS="-Os -ffunction-sections -fdata-sections -nostartfiles -nodefaultlibs" and then install it onto the host pc. I've used /usr/local/arm-none-eabi as the prefix, but it could of course be anywhere. The above already works for me on Debian unstable using libosmocore.git master. I have some patches pending in laforge/sercomm and laforge/pseudotalloc, but those are not mandatory to make the build work The local clone of libosmocore in OsmocomBB src/shared/libosmocore will be removed, and the Makefiles of osmocom-bb instructed to use the system-installed libosmocore from /usr/local/arm-none-eabi (see my 'laforge/remove-libosmocore' branch in). This also already "works" on my Debian unstable system, in as far as there are no unresolved symbols or other compilation/linking issues, and the firmware images are generated. I have not tested any of the resulting binaries yet, and as I'm travelling without compatible hardware (and overloaded), it's unlikely that I'll be able to test it soon. Nevertheless, this is what I would like to move to. If anyone wants to try if he can build the embedded libosmocore and resulting osmocom-bb from laforge/remove-libosmocore branch, please do so and report your progress/success/issues here. Next steps (after validating the above) are: * remove old sercomm.c code from osmocom-bb and use the new code from libosmocore * remove 'talloc emulation' from osmocom-bb and use pseudotalloc from libosmocore.git (plus an embedded 'malloc' like umm_malloc) Further ideas: * create Debian/Ubuntu package of cross-compiled libosmocore for embedded-arm, which we can add to the Osmocom nightly builds apt repository. * have an (optional?) osmocom-bb makefile step to git clone + configure + make install libosmocore Anyone interested in helping out with this, please feel free to join in.
