我已经改过了,依然不行,很惆怅。我这个板子的引脚是匹配的,但是无论有没有引脚检测,都不能行。

换个最新版的uboot,发现和 https://whycan.com/t_3633.html 帖子中的流氓兔遇到的问题是一样的,但是我降频了,串口也改了(可能没改对吧)依然不行。
特来求助一下。
这些二进制Blob非常有用,因为它们允许今天在Allwinner平台上具有完全正常的OpenGL加速:
作为稳定性测试,我们最近在Allwinner A33平台上运行了一个Qt5应用程序,
在Allwinner A33平台上进行OpenGL渲染24H*7,持续了1.5个月。
当然,从长远来看,我们将跟踪Lima项目的进度,
该项目将提供一个完全免费的开源解决方案,
以在Allwinner平台上提供OpenGL加速。
看来,还是挺稳定的

刚刚又翻了一下 buildroot 源码, 原来buildroot在2018年版本已经加入了:
https://github.com/buildroot/buildroot/tree/master/package/sunxi-mali-mainline-driver
这样不不需要自己费事手动加入代码了。

楼主推荐的闭源驱动可以自行添加到buildroot了: https://github.com/mripard/sunxi-mali
喜欢的朋友可以自己试一试。
