<ul><li><strong>Description</strong> updated (<a title="View differences" href="/journals/2070/diff?detail_id=2245">diff</a>)</li><li><strong>% Done</strong> changed from <i>0</i> to <i>10</i></li></ul>Here are the hardware issues I currently see.
<ol>
<li>Power is a USB mini-A and there are no headers to power like I'm doing with the B+. But there are holes for the headers so I could add them easily enough.</li>
<li>There is no audio-out on the Zero. I'd need a wifi dongle for that. There is one slot open for that. If I do that then I'll probably need a cable from the dongle to the external port on the player box otherwise I'll have to jam the dongle up against the current opening, and anchor the boards with something (a case?).</li>
<li>Uses a mini-HDMI port. Need mini-to-mini HDMI cable for use with the projector, preferrably very short one.</li>

<p>Closing this issue. We can reference it in closed state if needed but any hardware differences we can simply google and search for hats for components like the audio output.</p> Xeon - Action Item #562: Port to Pi Zerohttps://redmine.graphics-muse.org/issues/562?journal_id=24312019-02-08T22:10:14ZHammelmjhammel@graphics-muse.org

This may be due to the switch to device tree overlays since the last time I tried the Zero.</p>
<p>One possible fix is to use "device_tree=" (no value set) in config.txt to force the old behavior before device tree's were used. This may force the firmware to just use the kernel to determine what hardware to support.</p> Xeon - Action Item #562: Port to Pi Zerohttps://redmine.graphics-muse.org/issues/562?journal_id=24332019-02-08T22:38:23ZHammelmjhammel@graphics-muse.org
<ul></ul><p>According to the <a href="https://elinux.org/R-Pi_Troubleshooting#Coloured_splash_screen" class="external">RPi Troubleshooting</a> page, the kernel I have doesn't boot on the Pi Zero W. That seems odd, so I'm going to try booting this new kernel on a Pi 2 and a Pi 3 and see what happens. Maybe my kernel build got messed up.</p> Xeon - Action Item #562: Port to Pi Zerohttps://redmine.graphics-muse.org/issues/562?journal_id=24342019-02-08T22:46:06ZHammelmjhammel@graphics-muse.org
<ul></ul><p>Works fine on RPi 3. So it's the config.txt/cmdline.txt and/or kernel that seem to be the problem.</p> Xeon - Action Item #562: Port to Pi Zerohttps://redmine.graphics-muse.org/issues/562?journal_id=24352019-02-08T22:49:52ZHammelmjhammel@graphics-muse.org
<ul></ul><p>Hmm. Starting to look like the Zero may not be compatible with the 2/3: <a class="external" href="https://www.raspberrypi.org/documentation/linux/kernel/configuring.md">https://www.raspberrypi.org/documentation/linux/kernel/configuring.md</a><br />So I wonder how I got it to work the first time. Build with HW=rpi, possibly?</p> Xeon - Action Item #562: Port to Pi Zerohttps://redmine.graphics-muse.org/issues/562?journal_id=24362019-02-08T23:27:10ZHammelmjhammel@graphics-muse.org
<ul><li><strong>Status</strong> changed from <i>In Progress</i> to <i>Closed</i></li><li><strong>% Done</strong> changed from <i>50</i> to <i>100</i></li></ul><p>Verified: HW=rpi works with the Pi Zero W. It's chipset differences from the Pi2/Pi3. Anyway, I just need to use HW=rpi for the builds.</p>
<p>Closing again.</p>
