Hi,

I am trying out osmocom-bb with the Motorla C115. I have compiled libosmocore as a shared library and osmocom successfully. Also, I have compiled a "arm-none'eabi" cross toolchain from scratch. I get the following error:

$ osmocon -p /dev/ttyUSB0 -m c123 ~/osmocom-bb/src/target/firmware/board/compal_e88/hello_world.compalram.bin

Can the error be because of the toolchain ? Or can it be that my device is refusing connection with osmocon ?

Thanks in advance.
