Ramblings of a Osmocom supporter
by Henk 07 May '12

07 May '12

Hi all, First of all, what an exciting piece of hacking, well done guys! So after one year I revisited the osmocom and flashed the bootloader and the RSSI on my C116 device. I was wondering is there something of a TODO of sorts in order to get users of different skill levels involved? One thing I can think of is extending the loader with functions to access the DSP: read (p)rom, read write regs & memory, potentially adding DSP patching support. Regards, Henk

uwire.c relicensing
by Denis 'GNUtoo' Carikli 03 May '12

03 May '12

Hi, We(Alan Carvalho de Assis and me) also need the permission of Sylvain Munaut and Steve Markgraf for the relicensing of src/target/firmware/ of osmocombb for inclusion in nuttx(BSD licensed). What we need right now is to get the permission on that file: src/target/firmware/calypso/uwire.c Basically we want to add LCD support as quickly as possible to the compal e99(And in parallel to fix the configs and the linker scripts to get more space).

should we continue to focus on nuttx?
by Denis 'GNUtoo' Carikli 01 May '12

01 May '12

The other day on IRC I was told that: >Apr 29 00:34:36 <Hoernchen> last thing i heard was that nuttx was superseded in favor of a more lightweight solution And: >Apr 29 00:41:03 <steve|m> http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2012/Minutes#a18:30roundtabl… which was made back in march(we also started working on nuttx near march) and contains the following: >laf: summary we could not gain much from nuttx, rockbox could provide use with UI (inspiration)? steve: framebuffer is mosly compatible I wasn't aware of all that. Also I don't have much details on what was said since I wans't there... Should me and Alan Carvalho de Assis continue the work we are doing? What is the current plan? our status is here: http://bb.osmocom.org/trac/wiki/nuttx-bb/drivers The current work on my side is to: * make serial work without sercomm(done locally,just some configuration change) * unbreak the booting of the calypso(require serial to work without sercomm,the commit that created the problem has been identified, how to fix is a work in progress) * I also tried to change toolchain(I generated a toolchain with openembedded) to see if it fixed the issue but according to Gregory it's not the right fix. * I also identified some dummy functions in the nuttx version of sercomm that we should get rid of. On Alan Carvalho de Assis side : he's trying to make the keypad work but he has some difficulties with it. Denis.

Is there something I have missed? Thanks Tokala

Frequency hopping
by Dario Lombardo 27 Apr '12

27 Apr '12

Hello everybody What happens when a mobile station is in a cell that uses hopping, but the mobile locks to that cell (for instance using the function of the engineering menu of a BB)? Is the hopping mandatory or the ms can continue working also without it? Does osmocom support hopping? What are the commands of the mobile interface (if they exist) to show how the hopping is going? Is it possible to lock with osmocom too? Thanks for the answers. Dario.

Hello All, What is the preferred Sim Card Reader/Writer for the SysmoSim Card, A.K.A., the GrCard Sim? And is the following known to work reliably with the SysmoSim Card? SIM Reader kit - v1.0http://www.adafruit.com/products/101I contacted Adafruit.com yesterday and they explained that their device doesn't work on all Sim Cards. Any assistance would be greatly appreciated. Sincerely, Martin
