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 Are the instructions out of date on this page: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

Yes, the instructions are out of date. Meanwhile the chainloader has been integrated into osmocon, you just need to run:
./osmocon -p /dev/ttyUSB0 -m c140 -c ../../target/firmware/board/compal_e86/layer1.highram.bin

I tried but seem to be getting an error...
pi@raspberrypi ~/osmocom-bb/src/host/osmocon $ ./osmocon -d tr -p /dev/ttyUSB0 -m c140 -c ../../target/firmware/board/compal_e86/hello_world.highram.bin got 1 bytes from modem, data looks like: 00 . got 6 bytes from modem, data looks like: 66 74 6d 74 6f 6f ftmtoo got 1 bytes from modem, data looks like: 6c l Received FTMTOOL from phone, ramloader has aborted got 1 bytes from modem, data looks like: 65 e got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 72 r
I tried a different computer that is definitely faster and that didn't solve it. I am using a different serial cable, this one a home wired cp2102 where before I think I got this working with a direct wire to the raspberry pi alt serial pins.
Are there any links to describe what is going on at the beginning when you press the power button?
I found these links as well...

Thanks, Craig

Communications problem. Try different cables. If you had rpi working then go back to using that, rather than introducing new unknowns.

I got things working for both C115 and C139 w/ rpi, osmocom built natively on debian and a cheap cp2102 usb raw stick direct from china/ebay.
For C139
./osmocon -d tr -p /dev/ttyUSB0 -m c140xor -c ../../target/firmware/board/compal_e86/rssi.highram.bin
For C115
./osmocon -d tr -p /dev/ttyUSB0 -m c123xor -c ../../target/firmware/board/compal_e88/rssi.highram.bin
Sorry for the trouble... looks like "xor" and chainloading via -c were my two problems.

So I looked and there seem to be two board layouts involved here. The one's with the Intel flash seem to work fine. The others that have the MemoCom? flash don't work. The one's with MemoCom are missing several test points visible from the battery compartment as visible on the images on the webpage:
http://bb.osmocom.org/trac/wiki/MotorolaC140
So maybe there is something different about these other C140 that makes them not work with osmocon.
I get:
