如果是ubuntu24.04识别RM530n-GL的接口模块

技术专题 升级与调试
1

我在Rasberry Pi5上安装了ubuntu 24.04,并且通过pcie链接了RM530n-GL. 现在我可以识别出来这个模组. 但是我不能通过 ip a 找到端口. 我现在有如下驱动，需要帮忙看看如何安装这些驱动使ubuntu可以到RM530n-GL的端口. 我的需求是把RM530n-GL当作网卡模式来使用

英文论坛上你是否也提了对应的问题？
可以发下dmesg 日志。

3

那个可能是我同事,我只在这里提问过.
dmesg提示文件太大不能上传, 有没有可以加的过滤条件来减少一些输出

4

可以参考看。
ls /dev/ww* -al

5

root@local:~/driver/pcie_mhi# ls -l /dev/ww*
ls: cannot access ‘/dev/ww*’: No such file or directory

我这边都没有这个文件

6

sudo lspci -vvv 看看

7

抓取了中间两个

直接编译下pcie_mhi 吧，同时要把pcie_mhi_generic 卸载掉。

9

可能遇到的编译报错。

怎么编译和卸载这两个驱动. 有文档可以share么. bradleywang@outlook.com

11

这里有log 目录可以看看。怎么编译，直接make 就可以。

12

进入目录make的时候报错

root@local:~/driver/pcie_mhi# make
make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/6.8.0-1038-raspi/build M=/root/driver/pcie_mhi clean
make[1]: *** /lib/modules/6.8.0-1038-raspi/build: No such file or directory. Stop.
make: *** [Makefile:29: clean] Error 2

13

不确定是否是同一个板子。

这个树莓派的系统是你直接网上下载的吧，不是自己编译的内核.

14

对，就是用树莓派提供的软件装的标准的24.04的ubuntu的系统

15

下载的镜像可能不知道或者也就编译不了内核。
可以试试，先安装下内核头文件，具体怎么做自己搜下吧。

sudo apt update
sudo apt install -y build-essential bc bison flex libssl-dev libncurses-dev \
                    git raspberrypi-kernel-headers

sudo modprobe configs          # 确保 /proc/config.gz 存在
zcat /proc/config.gz > /tmp/config-running
uname -r                       # 例如 6.6.31-v8+
ls -d /lib/modules/$(uname -r)/build  # 应该指向 headers 目录

然后再试试在pcie_mhi 里make

16

另外再问一下， Quectel_Linux_PCIE_MHI_Driver_V1.3.8在 Ubuntu 24.04 6.8.0-1038-raspi是否兼容

17

make之后,已经不是unknown状态了, 但是在/dev下还是没有mhi的驱动. 也无法识别接口.

18

这个驱动要卸载掉。及其依赖的wwan等ko.

19

admin@raspberrypi:~$ lsmod | grep mhi
admin@raspberrypi:~$

这个generic没有了以后, lspci都识别不出来模组了

20

与mhi_pci_generic无关的。正常就算没有加载驱动，lspci 也能识别到。
