<p>WaveshareというAmazonで買える激安ディスプレイを販売しているメーカーがあります。今回このメーカーのディスプレイを使ってYoctoで作際したイメージのwestonを動かす際ハマったので備忘録として残します。</p>

<div class="code-block-container"><pre><code>If use the DSI0 interface, you need to add "dtoverlay=vc4-kms-dsi-7inch,dsi0" in the config.txt file
</code></pre></div><p>とあったので、<code>build/conf/local.conf</code>に以下のように追記。</p>
<div class="code-block-container"><pre><code>RPI_EXTRA_CONFIG = " \
    dtoverlay=vc4-kms-dsi-7inch,dsi0 \
"
</code></pre></div><p>あとはcore-image-westonをビルド。</p>
<div class="code-block-container"><pre><code>bitbake core-image-weston
</code></pre></div><p>これで問題なく動作しました。</p>
