| <h3>Advanced Usage<a class="headerlink" href="#advanced-usage" title="Permalink to this heading"></a></h3> |
| <p>In order to achieve a faster transmission speed, |
| I added a specific HEADER <code class="docutils literal notranslate"><span class="pre">STC</span></code> to the YMODEM protocol to represent the custom length. |
| Using the <code class="docutils literal notranslate"><span class="pre">sb</span></code> and <code class="docutils literal notranslate"><span class="pre">rb</span></code> commands on the board, you can use the <code class="docutils literal notranslate"><span class="pre">-k</span></code> option to set the length |
| of the custom packet, and the unit is KB. Therefore, you need to use <code class="docutils literal notranslate"><span class="pre">sbrb.py</span></code> for file transfer, |
| and you need <code class="docutils literal notranslate"><span class="pre">sbrb.py</span></code> -k to set the same length as the board. According to my test, |
| when using -k 32, it can reach 93% of the baud rate, |
| and is fully compatible with the original ymodem protocol. |
| First, you need to add a soft link to sbrb.py, for example <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">ln</span> <span class="pre">-s</span> <span class="pre">/home/<name>/.../<nuttxwork>/apps/system/ymodem/sbrb.py</span> <span class="pre">/usr/bin</span></code> |
| and then sbrb.py can be configured into minicom.``<Ctrl + a> z o`` then chose <code class="docutils literal notranslate"><span class="pre">File</span> <span class="pre">transfer</span> <span class="pre">protocols</span></code> and create two option cmd is ‘sbrb.py -k 32’. like this</p> |
