Query on TPU doc
by Bhaskar11 18 May '13

18 May '13

The TPU Debugger code lists: static const char *tpu_addr_name[0x1f] = { [0] = "TSP_CTLR1", [1] = "TSP_CTRL2", [*4*] = "TSP_TX_*1*", [*3*] = "TSP_TX_*2*", [*2*] = "TSP_TX_*3*", [5] = "TSP_TX_4", [6] = "TSPACT_L", ...... Was wondering if the numbering is a typo. Could not find documentation online. Just bringing to your notice for check. Could you please confirm that items 2,3,4 are not supposed to be in sequence. Thanks. B.

Game Snake for OsmocomBB
by Marcel `sdrfnord` McKinnon 17 May '13

17 May '13

Hi everyone I have hacked the game Snake for OsmocomBB. It was mostly for my own education and I thought I make a short announcement on this list that such piece of code also exists. Feel free to play around with it and merge it in the project repository if you want. Code: https://github.com/sdrfnord/osmocom-bb/tree/sdrfnord/ui A picture of the game: http://www.flickr.com/photos/sdrfnord/8626533489/in/photostream I developed and tested it for the C121. During development I also implemented fb_set_p to set one pixel and fb_bw8_line to draw a line. (For the ST7558 LC Display Controller) The code for fb_bw8_line is copied from http://de.wikipedia.org/w/index.php?title=Bresenham-Algorithmus&stable=1#Ko… I hope this does not interfere with the GPL … Another thing I added is twl3025_power_off_now for a fast reboot which I used for development. -- Kind regards Marcel `sdrfnord` McKinnon

[osmocom] Fucking battery
by choukoumoun 14 May '13

Hello My Motorola batteries are all swollen and therefore defective. anyone has a solution for connecting to power directly to the battery connector by usb? I thought used a 3.7V zener diodes in parallel between the - and + USB power and a series resistor. Thank you.

Which is the best branch for running mobile on DP-L10?
by ubuntugirl 13 May '13

13 May '13

Hello, I have just got myself a Pirelli DP-L10, and I would like to use it to demonstrate OsmocomBB to my local LUG. I would like to demonstrate mobile, talking to layer1 via osmocon, making and receiving a voice call, sending and receiving SMS. I only have a few basic questions: - Should I use the master branch in osmocom-bb git, or one of the other branches? The Branches page in the wiki is blank. - Am I correct in my understanding that, at least in some branch (see above), osmocom-bb does support this phone well enough to actually make a call? (Yes, I realize that layers 2&3 run on an attached host, hence the phone has to be tethered to a laptop running osmocon and mobile the whole time, and I do know how to enable Tx in the target build. :) - How is the voice routing implemented? Do I need to use lcr integration on the host, or will the audio come out of the phone's own speaker even though all higher layers of the stack are running on the PC? If the voice call audio does go through the phone's own speaker and mic, which ones? This phone model has both an earpiece speaker and a loudspeaker, plus the usual analog headset jack. Which of these audio routing options are supported, if any? Thanks everyone for this awesome project! I can't wait to show it working to my LUG. Kim

Pirelli DPL-10 nuttx work in progress?
by Craig Comstock 04 May '13

04 May '13

Hi all, So now I have nuttx console working via IRDA on my Pirelli DPL-10 phone. Here are my next steps... I wanted to see if anyone else was working on these? - port the osmocom fb driver over to a nuttx lcd driver - get layer1 + some version of "mobile" working on the device - write a custom UI so this can be my daily driver - and in relation to the last item... send a finished phone w/ firmware to be certified by the FCC? http://transition.fcc.gov/oet/ea/procedures.html Does that sound about right? Anybody working on any of these bits? I'm not expecting this to happen overnight by any means... just expect it to be interesting and a good learning experience. Thanks, Craig

Pirelli DPL10 - nuttx and dump flash for restore later
by Craig Comstock 02 May '13

02 May '13

Hey folks, I got my Pirelli DPL10 yesterday and was able to get hello world, rssi, layer1 etc up and working pretty easily. It's quite a bit easier than the other phones I was trying to use with my RaspberryPi. I was wondering if someone could give me a nudge on how to get started getting nuttx working on this phone? Also I'd like to ask if there are directions somewhere on how to save the standard software presently on the phone so I can restore it later. I looked at osmoload but didn't quite understand what to do. finfo seemed to come back with all zeros for information and I confirmed that ping received a pong from the phone. My goal is to work towards using osmocom/nuttx to make this phone my daily use phone. Thanks, Craig
