 You may have to specify the flashing port with
 `PORT_DEV=<my_openmote_port> make flash`
 
+The flash tool needs to convert the generated Hex file to RAW format.
+For this it needs to have the intelhex library installed.
+
+    apt install python3-intelhex
+
+or
+
+    pip3 install intelhex

 ### Flashing via JTAG
 
 To be able to flash the board via JTAG you need to install Seggers JLinkExe
