Loading HelloWorld firmware in Motorolla C118

Hello, I am trying to load helloworld firmware into my phone (Motorolla C118) using sysmocom CP2102-25 cable by executing the following command sudo ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/hello_world.compalram.bin But I am not getting any response on pressing power button briefly. The command keeps on executing without any message. What can be the issue and how to deal with/debug this issue. I have also attached a cu terminal by using following command. $ sudo cu -l /dev/ttyUSB0 -s 115200 The cu terminal displays this message on pressing power button. ��A@ftmtoolerror
