rssi chainload

Hello.

I'm trying to load RSSI firmware into my c123 phone. It's too big to be loaded
directly so it should be chainloaded. Unfortunately chainloading is almost
undocumented (or I failed to locate the documentation :)

As far as I understood it we use chainloader (small one) so it would load actual
payload (big one).

I've disabled size check in src/host/osmocon/osmocon.c:270 and recompiled latest git.

After that I've tried following:

./osmocom-bb/src/host/osmocon/osmocon -p /dev/ttyUSB0 -m c123xor -c
./osmocom-bb/src/target/firmware/board/compal_e88/rssi.highram.bin
./osmocom-bb/src/target/firmware/board/compal_e88/chainload.compalram.bin

but got only eternal stream of "Sending Calypso romloader beacon..."

Could you help me to figure out proper image names?

What's the meaning of -c option: the file to be loaded (big one)?
And as a last argument we supply actual chainloader (small one)?
