Hello everybody
I'm trying to use the RSSI firmware on a c118 and c115. Both of them give me this error

host/osmocon/osmocon -p /dev/ttyUSB0 -m c123xor target/firmware/board/compal_e88/rssi.compalram.bin 
got 1 bytes from modem, data looks like: 04  .

Received PROMPT1 from phone, responding with CMD
The maximum file size is 64kBytes (65535 bytes)
read_file(target/firmware/board/compal_e88/rssi.compalram.bin) failed with -27

Do I need to do something different to load this FW or simply my phones have no enough room for it? 

Thanks for your help.
Dario.
