@ylyamin 在 RT-Thread on D1H. LCD work, USB in progress. 中说：

I’m really stuck with the USB driver. It can detect device connections, but communication has not started.<br>
Perhaps someone would enjoy diving deep into the USB driver to solve this riddle. Ready for issue reports and pull requests.
Picture of LCD Display test in RT-Thread running on uConsole R-01:

nice work!
I'd like to help, and just bought a Sipeed Lichee RV board.

@linxingqianglai 参考前面的说明：

u-boot.fex 使用 linux3.4/uboot2011 的平台最终用到的 uboot,其实是uboot+sys_config。
boot_package.fex 使用 linux3.10/uboot2014 及更高版本的平台最终用到的 uboot,其实包含的文件由配置文件 boot_package.cfg决定，一般至少包含了 uboot和 dtb,安全方案会包含一些安全所需文件文件,可能还有 bootlogo 等文件。
toc1.fex 安全方案使用的 uboot, 类似 boot_package.fex说明,其中实际也包含了 dts 等多个文件。

@dazb3 there's a i2s doc on 100ask.net https://forums.100ask.net/uploads/short-url/3Da0tOrvGPKeV7Be36UVkzivSE6.pdf

to test i2s, why not try aplay or tinyplay?

more details will help.
I'm not sure but if you are using builtroot, python-spidev should be the package?

like this:
https://gerrit.cesnet.cz/plugins/gitiles/github/buildroot/buildroot/+/63d0762ab72a3536ea2e07ac75327c7556ed72c1/package/python-spidev/

没散热压不住吧，可以安装散热风扇吗？

@lknn2012 不用配，好像是uboot里会自动新增

@dazb3

chatgpt suggested no python-spidev is included by default, and should check python before add python-spidev.

3. Install python-spidev

python-spidev is usually not included directly in OpenWRT feeds, but it can be compiled from source as part of the build.

First, check for python3:

./scripts/feeds install python3

following is a link include python-spidev package by OnionIoT, switch to the right branch which matches tina sdk openwrt version:
