@大法师 你好，请教下这个unbut20.04版本好像没有适配npu的驱动，跑rknpu2仓库自带的sample一直报错：
E RKNN: [12:38:07.956] failed to open rknpu module, need to insmod rknpu dirver!
E RKNN: [12:38:07.958] failed to open rknn device!
不重刷其他版本系统，需要怎么处理呢？谢谢~

@jack_admin
不行呢，尝试了一下，还是报 insmod rknpu driver的错误

[大法师]

@night 加sudo运行试下

更新系统

USB移动硬盘刷机启动

[allen]

@大法师 22.04的镜像什么时候更新呢

[jack_admin]

@allen 22.04已有更新。

[bbsvs2000]

This post is deleted!

[ccjjww1222]

这两个镜像，我试了下，Xbox手柄都不行，免驱的（我的是无线手柄）。
原生的Ubuntu20 可以的
找不到 /dev/input/js0

[大法师]

@ccjjww1222
默认内核驱动未选择CONFIG_INPUT_JOYDEV。

后续默认选配再发布镜像，当然您也可以自行编译更新替换

[ccjjww1222]

@大法师 啥时候能发布？ 我自己编译的话，系统挂了。重新安装还要重新编译，麻烦。等你们的镜像

[shengxia]

请问一下，相同系统版本号，不同日期上传的特性哪里有介绍么？

[myhexb]

为什么我 两张闪迪 一张京东卡 离线刷 只有京东卡可以用，闪迪的不能用，而树莓派三张卡全能用，而京东卡虽然读取速度也有100MB/s 但巨卡，20.04 鼠标都卡的动不了开机得10分钟是什么原因

[george]

@myhexb 串口打印一下启动的日志信息，发上来。

[大法师]

@myhexb 用哪个镜像文件测试？

[myhexb]

@george 完全启动不起来 可以打印日志吗 该怎么打印 反复显示 cool pi

[myhexb]

@大法师 用的官方文件百度网盘ubuntu文件夹里的 20.04桌面版 3.52g的那个

[myhexb]

@大法师 闪迪的卡就像没插卡一样，反复显示 coolpi 京东卡可以进去 但特别卡，而且非正常关机后大概率也会进不去系统，不过一般会卡到 - 界面。需要重新刷机才行

@myhexb 这个是镜像没有制作成功。如果有读卡器可以先格式化一次卡，然后再制作，闪迪的卡我一直在用，没有什么问题。

@george 第一张闪迪卡各种方式格式化 试了4 5次了 ，第二张也试了一次 还是不行

[george]

@myhexb 可以换个镜像再测试。从log看的情况就是卡没有识别到或者rootfs没有成功挂载。

@george 换22.04 也还是一样的情况

@myhexb 用读卡器连接，插在USB3下层端口，启动试试

@大法师 试了 usb插 硬盘盒子和 读卡器 还是只有京东卡可以启动，闪迪卡可以找到卡 但不能启动 ，重做和换镜像文件都没成功，0 2 1 3 6 8 7 9 trsv ln0 mon rx cdr lock timeout

@大法师 硬盘盒子干脆就找不到usb设备 ，

硬盘盒需要更新loader，且需要注意适配器供电功率
