Re: UI work - qemu and key repeating

by Craig Comstock

> > I'm writing some UI/firmware [...] > That sounds neat... are you doing it in some visible git repository perchance? I'm just hacking on layer1/main.c right now. Not even sure I would put in a repo since I want to implement some form of t-9 character and word fanciness. Maybe I could make that a module or think of an open-source/free paradigm for entering text w/ the keypad. http://www.google.com/patents?id=PmgCAAAAEBAJ (T9) http://www.google.com/patents/US3967273 (funny bell labs method using two key presses always) (the list goes on and on I think...) My thinking is that I might start with this hacked layer1 and gradually try to bring bits of mobile into the firmware/ui. Also just wanting to fiddle around with how the phone will "feel" with a console interface. aka UI prototyping. Cheers, Craig

UI work - qemu and key repeating

by Craig Comstock

Was wondering if anyone has tried to use qemu to make a device emulator? I'm writing some UI/firmware and it seems like it might be a nice way to iterate on code. Also was thinking I would need to rework keypad.c so that I can get key hold/repeat events since I want to know when a key is being held down at some fairly short interval. Any suggestions/previous work/cautions? Thanks, Craig

chainload.compalram.bin missing?

by Craig Comstock

I was trying to load some apps to a Motorola C139 and found that after building osmocom-bb that there were no chainload image files built. Am I using the wrong branch somehow? Are the instructions out of date on this page: http://bb.osmocom.org/trac/wiki/MotorolaC140 ./osmocon -p /dev/ttyUSB0 -m c140 -c ../../target/firmware/board/compal_e86/layer1.highram.bin ../../target/firmware/board/compal_e86/chainload.compalram.bin The page mentions something about a magic value that must be placed into memory for the bootloader... could that be added to osmocon somehow so that specifying -m c140 takes care of it? "After the download has completed, it expects the magic string "1003" (0x31 0x30 0x30 0x33) at the RAM address 0x803ce0" Thanks, Craig

Uplink sniffing

Dear all, I was wondering if uplink sniffing is enabled by default in latest firmware as file "osmocom-bb/src/target/firmware/layer1/prim_sniff.c" has been modified and does not hold "#if 0" bit at line 288 anymore. Thanks, George Andguladze
