Thank you. But what about the rockchip loader that loads u-boot? The loader that helps to flash u-boot. I think its part of rkbin. When I try to flash new u-boot, with uart2 gone, I'm blind.

The cloud drive provides a complete firmware package, including U-Boot, kernel, and RootFS. If you only ...

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。

这个镜像的音频没有问题，请注意录制的顺序。Wiki 文档上的录制命令顺序有误，我们会尽快进行修正。
arecord -D main_mic0 -f cd -c 2 -r 48000 test0.wav # 耳机麦克风录制
arecord -D main_mic1 -f cd -c 2 -r 48000 test1.wav # 板载麦克风录制

Please find attached the configured device tree and kernel image.

Touch functionality is not enabled in the default kernel. To enable touchscreen support, follow these steps:

1. Copy the driver source file: sudo cp edt-ft5x06.c sysdrv/source/kernel/drivers/input/touchscreen

2. Run the kernel ...

If you are using an HDMI display, you can use the image under the “Customized image” directory in the cloud drive. This image does not have the scheduling issue.

Alternatively, you can compile it yourself—the issue has already been fixed in the new SDK.
