<p>When building Flickernoise, the file <code>bin/flickernoise.elf</code> contains the debug information. Starting with Flickernoise 1.0RC1, this file is provided with the releases to make debugging easier. With

earlier versions, you have to compile Flickernoise yourself (the <a href="https://github.com/milkymist/scripts" class="external text" title="https://github.com/milkymist/scripts" rel="nofollow">build scripts</a> automate that).

<p>Use these commands in GDB:
|
|
</p>
|

<pre>set remote interrupt-on-connect on

set remote interrupt-sequence BREAK

target remote /dev/ttyUSB0

|
|
<p>To use it start flterm with --gdb-passthrough. Then start gdb and run the following commands:
|
|
</p>
|
|
<pre>set remote interrupt-on-connect on
|
|
target remote <pseudo terminal printed by flterm>
|
|
</pre>
|
|
<p>Note: there is _no_ 'set remote interrupt-sequence BREAK'. flterm takes
|
|
care of converting Ctrl+C (ETX) to a BREAK.
