Hi all
by Erik Ekman 01 Mar '10

01 Mar '10

I have ordered a C139+cable and I am waiting for it to arrive. I guess the helloworld and other binaries will run on it but the peripherals that differ from the C123 will not work. Is that correct? At work we used ARM7TDMI, now an ARM9, and we looked at FreeRTOS before going for a custom non-RTOS event-based os. We use the gnu toolchain and OpenOCD. So far, I have only used GSM/GPRS from the AT-command level, but it looks interesting to see more. While waiting for the hardware I did some trivial patches for osmocon that are attached. Hope that form (as well as the content :) is acceptable. /Erik

more c118 testing
by chekov 01 Mar '10

01 Mar '10

hi, i'd like to do some more c118 testing. the only tool i further got to work was l1test.bin[1]. the others were downloaded correctly but ended up /blue/ :) is it worth the time to make some tests with older object-code-versions? otherwise i will investigate what happens to compal_dump.bin[1], because this one answers with some "Dropping sample" lines. attachments: [1] l1test.bin.txt [2] compal_dump.bin.txt l1test.bin $ ../osmocom-bb/src/host/osmocon/osmocon -m c123 -p /dev/ttyUSB0 ../osmocom-bb/src/target/firmware/l1test.bin got 1 bytes from modem, data looks like: 04 got 1 bytes from modem, data looks like: 81 got 5 bytes from modem, data looks like: 1b f6 02 00 41 got 1 bytes from modem, data looks like: 01 got 1 bytes from modem, data looks like: 40 Received PROMPT1 from phone, responding with CMD read_file(../osmocom-bb/src/target/firmware/l1test.bin): file_size=31836, hdr_len=4, dnload_len=31843 got 1 bytes from modem, data looks like: 1b got 1 bytes from modem, data looks like: f6 got 1 bytes from modem, data looks like: 02 got 1 bytes from modem, data looks like: 00 got 1 bytes from modem, data looks like: 41 got 1 bytes from modem, data looks like: 02 got 1 bytes from modem, data looks like: 43 Received PROMPT2 from phone, starting download handle_write(): 4096 bytes (4096/31843) handle_write(): 4096 bytes (8192/31843) handle_write(): 4096 bytes (12288/31843) handle_write(): 4096 bytes (16384/31843) handle_write(): 4096 bytes (20480/31843) handle_write(): 4096 bytes (24576/31843) handle_write(): 4096 bytes (28672/31843) handle_write(): 3171 bytes (31843/31843) handle_write(): finished got 1 bytes from modem, data looks like: 1b got 1 bytes from modem, data looks like: f6 got 1 bytes from modem, data looks like: 02 got 1 bytes from modem, data looks like: 00 got 1 bytes from modem, data looks like: 41 got 1 bytes from modem, data looks like: 03 got 1 bytes from modem, data looks like: 42 Received DOWNLOAD ACK from phone, your code is running now!

layer2/3 interface
by Harald Welte 01 Mar '10

01 Mar '10

Hi! I'm currently working on getting the integration between l1, l2 and l3 running. As it seems to me, using at least the RLL part of RSL as an interface between l2 and l3 seems to make a lot of sense. After all, it contains all information we need, such as timeslot/subslot/sapi/... and supports all the various {data,unit_data,establish}{{request,indication} messages. So my idea is to generate a RSL RLL message in L2 and send ot to L3 and vice versa. I'll commit it to the 'uplink' branch as soon as I have something useful. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Have you turned the Auxiliary DAC on ? It has its own power control bit and bit 5 (ADACS) in TOGBR1 hat to be set to turn the Auxiliary DAC on.

batter charging interface / iota madc block
by Joachim Steiger 28 Feb '10

28 Feb '10

sorry for not writing anything earlier, but i'm currently moving so i'm a bit short of time. i have been working on the bci and madc block already, so if you are not already done, i'd like to do that. its a bit tricky since one needs to do quite a lot to charge the battery correctly, but in the end we could even charge nimh and i guess small lead batterys also if we want to (with different code). i have done the irq handlers, the charger plug in detection and the async madc stuff is already working. it just needs some cleanup before commit. about the bci stuff: i'm now done reading and understanding the iota datasheets and appnotes (the latter one having invaluable information not in the datasheets). 'just' need to get it written down in code and debug it. ;) summary: if you can live with charging your batteries for another week or 2, just try figuring out the ringer and or vibra for example ps: according the the schem the vibra should be controlled by the auxdac of iota. i poked it and some enable bit few minutes, but couldnt get it doing anything. so there is still a mystery or 2 left. kind regards -- roh

Bootloader
by Ingo Albrecht 27 Feb '10

27 Feb '10

Hi everyone Without further introduction and in a similar manner to laforge's last mail I would like to note that I am working on a bootloader that will allow for larger binaries in RAM and flexible flashing. To avoid troublesome interaction between the Calypso bootrom (which we use for interrupt redirection) and CFI support, I have decided to go for an interrupt-less approach. So don't be surprised to see me committing a polling mode to fundamental drivers (keypad, uart) sometime soon. Luckily, the required changes are trivial. I'll push my branch sometime soon, just dropping a line to keep everyone informed. Feel free to drop a line in case you are interested in other flash-based tasks like hammering out linkage details and implementing some kind of filesystem. Greetings prom

C155 display driver

Hi! Just to avoid any possible duplicate work: A member of this list already has a working C155 color display driver. So if you were thinking of working on this: Please rather do another TODO item. I'm supposed to be merging that driver during the next couple of days. Cheers, Harald p.s.: I'm back in Berlin now, will be working with zecke of getting layer2 (bi-directional) up and running. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Hi, First I'd like to thank all people involved with the project. I don't know about GSM but as Harald said [1] I can contribute with microcontroller development. I have an old functional Motorola C200 phone. I'd like to know if it's possible use it? I've search for some information about C200 baseband processor without success, so I'm asking in the list.
