[GitHub] [incubator-nuttx-apps] normanr opened a new pull request #974: system/uniqueid: Add a tool to get the board uniqueid

normanr opened a new pull request #974:
URL: https://github.com/apache/incubator-nuttx-apps/pull/974


   ## Summary
   The `uniqueid` tool provides a way to get the board uniqueid from userspace.
   
   ## Impact
   This is useful to be able to set the hostname in startup scripts (for example). It includes command line options to:
   - select which bytes of the uniqueid you want to print (1 indexed, like the `cut` tool)
   - include a prefix (so that `NSH_ARGCAT` is not required)
   - print a delimiter between each byte
   - format the bytes (hex, HEX, decimal, octal, char)
   
   ## Testing
   ```
   nsh> uniqueid
   010203000a0b0c0048656c6c6f000000
   nsh> uniqueid -p nuttx- -b 4-6
   nuttx-000a0b
   nsh> uniqueid -d: -fd
   1:2:3:0:10:11:12:0:72:101:108:108:111:0:0:0
   nsh> uniqueid -b 9-13 -f c
   Hello
   nsh> uniqueid -b16-1
   0000006f6c6c6548000c0b0a00030201
   nsh> uniqueid -b9-16,1-8
   48656c6c6f000000010203000a0b0c00
   nsh> uniqueid -b9-16,1-9
   ERROR: Too many bytes selected
   nsh> uniqueid -b 0-5
   ERROR: Invalid byte position: '0'
   nsh> uniqueid -b 10-17
   ERROR: Invalid byte position: '17'
   nsh> uniqueid -bx
   ERROR: Invalid byte position: 'x'
   nsh> uniqueid -b1-5-8
   ERROR: Invalid byte range: '1-5-8'
   ```
