      可以先用buildroot版本镜像验证CSI摄像头,Ubuntu与其他发行版本还在优化适配中。

      对应镜像下载地址在百度网盘,请参考贴

      @retroman Hey! Do you mean of the Amazon cards? I've actually found that the 128GB model I have is slightly slower in most areas than the 64GB cards, so it's the 64GB one I recommend in most cases!

      I wouldn't be able to say where the difference is exactly, I use the same microSD card on the board and they're all just blank cards with an ext4 filesystem on them tested in exactly the same way. I'd have perhaps expected both of them to be closer than they are but in the boards I've tested with the 128 so far (I only picked it up over Christmas) it's been consistently slower than the 64 but still very good overall.

      机器没有识别到这个HDMI设备。可能是接口或者分辨率非标准导致。
