 ## Introduction
-These are the step by step instructions on Cross-Compiling Arm NN under an x86_64 system to target an Arm64 system. This build flow has been tested with Ubuntu 18.04 and 20.04 and it depends on the same version of Ubuntu or Debian being installed on both the build host and target machines. The instructions assume you are using a bash shell and show how to build the Arm NN core library, Protobuf, Tflite, Flatbuffer and Compute Libraries.

 ## Troubleshooting and Errors:
+### Missing xxd
+* When Cross-compiling Arm NN if you are getting error
+```bash
+[ 62%] Generating SchemaText.cpp
+/bin/sh: 1: xxd: not found
+make[2]: *** [armnn/CMakeFiles/UnitTests.dir/build.make:63: armnn/SchemaText.cpp] Error 127
+make[1]: *** [CMakeFiles/Makefile2:674: armnn/CMakeFiles/UnitTests.dir/all] Error 2
+make[1]: *** Waiting for unfinished jobs....

+* Missing xxd, this can be fixed by installing it:
+```bash
+sudo apt-get install xxd
+```
