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)?
