Re: UI work - qemu and key repeating
by Craig Comstock 29 Aug '13

29 Aug '13

> > 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 27 Aug '13

27 Aug '13

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 22 Aug '13

22 Aug '13

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 Are the instructions out of date on this page: http://bb.osmocom.org/trac/wiki/MotorolaC140 ./osmocon -p /dev/ttyUSB0 -m c140 -c ../../target/firmware/board/compal_e86/layer1.highram.bin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
