UART_downloader

This script downloads files over a UART connection. It can even download entire disks or partitions.

Small warning

This is just a script that worked for my need. It might work for other applications and it might not.

All configurations have to be made inside the c file, but I've left some comments so you know what to change.

Prerequisites

1. GCC

2. UART shell

This script works by running dd on the target device. Make sure you have a shell where dd is accessible. The script probably works if you replace dd with cat in some cases.

Additional notes

Sometimes your shell might not support piping binary data to sdtout. If this is the case, add some sort of encoding to the data. On the router I ran this on, I could add | openssl base64 to the end of the command to get encoded data. This should work for other encodings depending on what you have available.
