@Lemon1151 Really hoping someone can help me out.

I’m writing to ask if you could please add support for my device. I’ve extracted the device tree from the official Ubuntu 20.04 image and from the board itself. There’s...

第三方构建已知问题： - tf 卡读卡器无设备，mmc_host 只有 mmc0 - EC20 模块无设备，lsusb 不显示 - LED蓝灯闪烁（最外侧），官方固件是紫灯闪烁（最内侧） - USB OTG 口无法使用，用于 MASKROM 下载

> 根据你提供的资料，我添加了这个设备，你到releases里下载名字带dc-a588的固件，测试下是否启动正常。 感谢合并，试了无法启动，hmdi无输出，我在公司没有ttl，晚点看一下调试口，能否参考这个https://github.com/Lemon1151/ubuntu-rockchip/commit/e2e9eeb479cf38a828f39cc5eaffbaf35a538b4e 他的可以正常启动，以及gpu加速。

@ophub 实在不好意思，是因为设备双 HDMI，我今天碰巧有点忙没注意，中间HDMI无输出，另外一个HDMI（HDMI0）是正常的，我之前说 HDMI 输出是我没测试另外一个。 另外超出显示器范围了，我的显示器是3440x1440，可能适配有点问题？长宽比限制16:9？
