As said in the topic, I don't know what is the difference between the two
.bin file. And when I try the osmocon app, only the
hello_world.compalram.bin works, why?
Thanks in advance.

hi,
the e88flash.bin is compiled for running from flash memory rather than ram.

Thank you for your replying!
I see that difference. When I try to run the following command, it works,
but if I change FIRMWARE.compalram.bin to FIRMWARE.e88flash.bin, there is no
result.
$ ./osmocon -p /dev/ttyUSB0 -m c123xor
../../target/firmware/board/PHONE_TYPE/FIRMWARE.compalram.bin
And one more further question, if I want to write a firmware file by myself,
how can I manage to compile it running in ram or flash?

It's just not intended to be used like that. These firmwares
are used by the osmocom loader in case you want to flash an
application. For more information regarding flashing firmwares see
http://bb.osmocom.org/trac/wiki/flashing
$ ./osmocon -p /dev/ttyUSB0 -m c123xor
../../target/firmware/board/PHONE_TYPE/FIRMWARE.compalram.bin

Have a look at src/target/firmware/Makefile, you can
basically generate both versions by adding your
application there.
