It depends on the communication medium between the raspberry and the microcontroller. For instance if you are using the UART (serial communication) then you have to implement a (very simple) protocol for transferring binary data.

So you are probably using a USB to TTL converter. At first, make sure you are able to read and write simple strings. Then, you could try transferring binary blocks of data. In a minimalistc approach you first transfer a header (containing file info like, length, etc...) then trasfer a sequence of binary blocks of data (the file itsef). You should probably use a CRC on every block.
