</span>This is a problem that comes up fairly often, and is a bug with the BSP layer<br>
itself. All BSP layers are supposed to be created so that they work well when<br>
intermixed with other BSP layers, but often they don't. See Angstrom:<br>

The fact you mention this problem and meta-rockchip-extra implies to me that<br>
you're using the vendor-provided meta-rockchip and meta-rockchip-extra:<br>

The problem is, the vendor is only interested in their own hardware, so to<br>
them there's no reason to ever mix their BSP layer with any other BSP layer.<br>
There's no interest on their part to "play well" with others or to check<br>
whether their layers comply with community guidelines.<br>
<br>
As a person who likes OpenEmbedded as a whole, I try my best to make sure any<br>
layer I'm interested in plays well within the entire OpenEmbedded ecosystem.<br>
However, because mali graphics are currently all binary blobs and projects<br>
like Lima and Panfrost aren't yet ready for prime-time, there isn't much<br>
support yet for _accelerated_ graphics in the non-vendor layer.<br></blockquote><div><br></div><div>I hope some of these open projects will success to improve the current situation. <br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">>   - Can you suggest a fix to solve this issue?<br>

</span>Fix the problem in the layer by using MACHINE-specific OVERRIDES and submit<br>
a pull request to the owners. However, I've noticed there haven't been any<br>
updates to their OE layers in the past 4 months or more, so I can't help<br>
wonder if they've abandoned them.<br></blockquote><div><br></div><div>Will try to fix it as suggested and will send the PR.</div><div><br></div><div>Â </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Out of curiosity, which MACHINE(s) are you interested in?<br></blockquote><div><br></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Current working platforms are:</span></div><div>Â Â * Intel Celeron J1900 (meta-intel).<br></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Â Â * Rockchip RK3288 Merrii-K2 (meta-rockchip)</span><br></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><br></span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Planning to start working with some Allwinner-based board (meta-sunxi).</span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><br></span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Have a nice day! :-)</span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><br></span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Kind regards,</span></div><div><span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">Â --Â Ivan</span></div><div><br></div></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><br><div class="gmail_signature" data-smartmail="gmail_signature"><br><br></div>
