LicheePi Nano Usb复合设备RNDIS功能问题

lanjackg2003 · 2019-09-15 22:01:35

在做USB复合设备的时候，参考了晕哥之前的文章
https://www.lotlab.org/2018/07/29/record-of-using-licheepi-part-2-using-linux-gadget
目前，usb的串口功能可以正常与板子进行交互，但是RNDIS的功能却没有成功
开机启动的时候，在加载脚本的时候出现 /usr/bin/myusbgadget: line 41: udevadm: not found
如图片所示
失败图片

我查了系统，确实没有udevadm这个程序。
请问一下，要如何解决这个错误，让系统支持RNDIS功能
请大家赐教，谢谢

另外附上myusbgadget脚本的内容

udevadm 这个命令没有找到，这个是干嘛用的?

晕哥 · 2019-09-15 22:10:56

我去看下 buildroot有没有

晕哥 · 2019-09-15 22:20:24

https://github.com/gentoo/eudev/blob/master/src/udev/udevadm.c
https://github.com/systemd/systemd/blob/master/src/udev/udevadm.c

找到了这两个, 在 buildroot里面开启 eudev 或 systemd, 应该都可以生成 udevadm 命令,重新打包文件系统即可.

按照你的方法，在buildroot开启了eudev方式,可以支持udevadm了
但是在 /etc/inittab 文件中添加

ttyGS0::respawn:/bin/getty -L ttyGS0 57600 vt100

重新开机后，此时一直提示

can't open /dev/ttyGS0: No such file or directory

具体的log打印如下

想使用命令

modprobe g_serial

加载起来,但发现返回错误

modprobe: can't open 'modules.dep': No such file or directory

感觉是驱动没有加载，请问要如何解决这个问题？
目前是usb的串口跟RNDIS都无法工作

你装的是g_cdc驱动，但是脚本用的configfs。内核选项里关掉legacy usb gadget，启用configfs usb gadget再试试。

是这个问题吗?

这个问题是因为你的modules没有安装正确:

但是没有问题还是那样子

重新执行前面的 modules_install
https://whycan.cn/files/members/1741/2019-09-18_21-12-44.png
重新安装也仍然没有生成 modules.dep.bin, modules.dep 这两个文件

参考链接
http://blog.chinaunix.net/uid-10386087-id-2959091.html

如文章说的那样情况，查看了我的编译环境，发现确实没有 depmod 这个命令
通过如下命令安装

sudo apt-get install module-init-tools

然后再重新执行

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=/opt/lichee/buildroot/output/target/  make modules_install

可以看到现在能够正常生成 modules.dep.bin, modules.dep 文件了

晕哥说：

不完整, 缺 modules.dep.bin, modules.dep

删除 lib/modules/4.15.0-rc8-licheepi-nano+/ 目录:
rm lib/modules/4.15.0-rc8-licheepi-nano+/ -rf
重新执行前面的 modules_install

现在modules.dep.bin, modules.dep 可以正常生成了，但是没有办法加载起来

# modprobe u_serial
modprobe: module u_serial not found in modules.dep
# modprobe g_serial
modprobe: module g_serial not found in modules.dep
# ttyGS0::respawn:/bin/getty -L ttyGS0 57600 vt100
-sh: ttyGS0::respawn:/bin/getty: not found
#

晕哥 · 2019-09-18 22:55:50

勾选 usb gadget 相关选项,确认生成了 g_serial.ko

串口已经正常工作了
现在RNDIS还是有问题，加载不起来

lanjackg2003 · 2019-09-19 00:04:15

通过以下命令加载驱动

# modprobe g_ether
# /usr/bin/myusbgadget
[   37.326944] using random self ethernet address
[   37.331582] using random host ethernet address
# ifconfig usb0 192.168.1.66
ifconfig: SIOCSIFADDR: No such device
#

Win10的设备管理器，没有看到任何新的设备。

RDNIS驱动应该加载那个驱动呢？

g_acm_ms.ko        g_ether.ko         g_midi.ko          g_serial.ko
g_audio.ko         g_ffs.ko           g_multi.ko         g_zero.ko
g_cdc.ko           g_hid.ko           g_ncm.ko           gadgetfs.ko
g_dbgp.ko          g_mass_storage.ko  g_printer.ko
#

或者应该如何才能够支持RDNIS?

另附上我的内核启动日志

你先卸载 g_serial: modprobe -r g_serial

然后才可以用 g_ether

多谢楼主分享，之前按照< 测试测试 g_serial / g_ether USB Gadget (RNDIS)>帖子没成功，

以后试试楼主的。

勾选 usb gadget 相关选项,确认生成了 g_serial.ko

我可以顺利得到g_serial.ko g_ehter.ko g_multi.ko 和 modules.dep modeles.dep.bin 这几个文件
下一步不知道该怎么弄了

我现在用的荔枝派ZERO采用的是TF卡烧录boot，拷贝zImage .dts 文件，解压roofts.tar的方式工作的

难题在于得到了驱动文件之后不知道该怎么加入到我的荔枝派当中来运行
是直接把那些文件拷贝到TF卡里面的特定位置在加载吗？

1. 你的g_multi.ko完整路径是什么

2. 你的zImage和ko是同一次编译的吗?
