Hi, im having some problems in software only, that i describe bellow in my log:

-FTDI based interface sold by tronix (vendor link on your site), usb2 to serial adaptor ( model TRX1227, CHIPSET FT232R )
-gnuarm&osmocom compiled from source on debian stable as per osmocom without a single problem.
-ran osmocom from su (tried user as well), as instructed and as follows:

$ ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin

output: 
whenever power button was pressed, all i got was some aparently random hex…(no expert on phone flashing here) with no getting to PROMPT1:

"root at box:/home/box/osmocomm/osmocom-bb/src/host/osmocon# sudo ./osmocon -p /dev/ttyUSB0 -m c123 ../../target/firmware/board/compal_e88/loader.compalram.bin

Same output, (maybe with a few more presses) in hex, using gtkterm at 115200baud,8bit,nopar,1stop:

-/dev/USB0 permission check - good, even chmoded 777&chown on rc.local.
-cable check: thought txd was broken, but wasnt. checked from linux
with a led stuck to the txd end of the jack, echo "whatever" > /dev/ttyUSB0, led did flash.
-chances i put are:
osmocom dependent on some specific C123 firmware?
some kind of hidden compilation complication?
some kind of ftdi eeprom config/bitrate/parity config missing for osmocom?

I hope i have managed to be concise enough.
Great work guys.

Greatings from portugal,
Filipe RC
