Open GSM firmware - OsmocomBB supports Neo FreeRunner

by Martix

Hi! There is some GTA02 support in OsmocomBB project. You can flash open source firmware for TI Calypso GSM modem. http://bb.osmocom.org/trac/wiki/OpenMoko Did anybody tried this firmware on his Neo FreeRunner? What's your experience? Is it usable with SHR or Qt Moko like old proprietary firmware? Calls, SMS, GPRS, SIM load/store (contacts, SMSs) works? How many successfully flashed devices are here? And how many bricks? ;-) I know about OsmocomBB from beginning, but Openmoko smartphones support wasn't priority for them. I'm glad to see some progress on GTA02. Did leaked documentation and proprietary firmware source codes helped OsmocomBB? http://lists.openmoko.org/pipermail/community/2011-November/065731.html Best Regards, Martix

replacing sercomm tranfer with direct function

by Akib Sayyed

l1_queue_for_l2(struct msgb *msg) will queue data from layer1 for layer2 and will send via serial to host now if i directly replace all layer2_read content and pass msg to l1ctlrecv will it work on target host == host pc target == phone any suggestion on this and l1a_l23_rx this will receive data from l23 from host is it correct Note: I am trying to implement l2l3 on phone it self -- Akib Sayyed Matrix-Shell akibsayyed(a)gmail.com akibsayyed(a)matrixshell.com Mob:- +91-966-514-2243

GSM Paging Request

by Ryan Hayes

Hi, I am confused about the paging request when monitoring channel bursts, is the return downlink say from TMSI only reviewed by the BTS or is it accessible from the layer23 forwarding wireshark? more mods needed in development kit? Thanks

Re: Pirelli DP-L10 keypad

Hi Kevin, On 07.07.2012 11:15, Kevin Redon wrote: > - the additional volume up/down and camera buttons press are detected > by keypad_poll(), but not visible in KBR_LATCH_REG Yes, for that you need to increase the number of rows/columns that are scanned (can exactly remember which one). The Compal phones don't use all of them. > - the power button press is not detected by keypad_poll() (or ignored > by > "with_interrupts && !polling") As it seems the power button is not connected to the keyboard scan matrix. You get an interrupt from Iota though when the button is pressed, see [2].

Did you check out the steve-m/pirelli branch [2]? It already contains the modified keypad header. Those changes should definitely be cleaned up and put into master, especially make the UARTs runtime configurable to have them swapped for the DP-L10.
