我们目前还没有移植过该驱动，因此暂时无法提供有效的建议。
另外，这部分内容已经超出了我们的技术支持范围，敬请理解。

Please download the image again. The image uploaded yesterday did not include the updated U-Boot, so it could only output kernel logs.

The new image has been updated and should work correctly.

All interfaces are directly output from the chip, so any damage cannot be repaired. I will compile an image for you using UART7 (GPIO3_C4, GPIO3_C5) as the debug serial port.

This screen is not yet supported in the driver, so providing a device tree alone will not allow it to function. The driver must first include support for the screen before a usable device tree can be provided.

The same Debian image works for both eMMC and microSD card.

Ubuntu系统商用属于侵权，我们已经不维护了，因此暂不支持设备树修改相关需求。
如果是批量采购我们的开发板，可以联系销售同事拉技术交流群，我们可以协助评估整体方案，并根据项目需求提供适配建议。
