你下载测试下，我看官方支持主线，所以我选择了主线内核6.6.y，你试试这个内核是否可以使用。之前的rockchip都是使用的独立分支。

T6硬件有两个版本，一个是最早发布的2301版本，Linux主线内核和Armbian社区支持的也是这个版本，后来友善又改了一个新版本LTS（2310），现在销售的也是LTS版本了，两个版本的设备树基本通用，区别是LTS增加了两个USB2.0接口，有一个GPIO去控制供电，还请O大把LTS也一起支持了吧。

硬件差异参考：https://wiki.friendlyelec.com/wiki/index.php/NanoPC-T6#NanoPC-T6-LTS

需要修改的部分可以参考这里：https://github.com/friendlyarm/kernel-rockchip/blob/nanopi6-v6.1.y/arch/arm64/boot/dts/rockchip/rk3588-nanopi6-rev07.dts

我看armbian使用的是主线内核，看友善使用的是rockchip专用内核，你有哪个设备，你测试下上面的固件是否可以正常启动。上面使用的是主线的linux-6.6.y，如果可以使用的话，可以把这个LTS提交到6.6.y里。

[cm9vdA]

我有LTS版本的，周末我回去刷下试试再给你反馈。

今天试了，可以正常启动进系统，但所有的USB接口都不能使用，USB2.0和USB3.0没有5v供电，Type-C有供电但不识别设备

我根据友善的源码试着改了下，拉高GPIO_1 RK_PA4可以开启USB2.0的供电，USB2.0可以用了；GPIO_4 RK_PB0是控制USB3.0的供电，但是我试了下，拉高以后USB3.0还是没有5v电压。

从Armbian官网下载的社区版T6固件除了USB2.0，其他都正常，额外添加GPIO_1 RK_PA4的配置以后就全都正常了，但这个dtb放在你的固件里启动不了

2301版本，正常启动，usb3.0无法使用。可能是我提供的dts有问题
https://github.com/friendlyarm/kernel-rockchip/blob/nanopi6-v6.1.y/arch/arm64/boot/dts/rockchip/ 有多个版本，估计能有好用的

[ophub]

https://github.com/unifreq/linux-6.6.y/blob/main/arch/arm64/boot/dts/rockchip/rk3588-nanopc-t6.dts

我用的是这个dts编译的，测试一下修改的内容在这个主线内核里可以编译，把修改提交到f大的这个仓库吧。
